Starting with 1.47, changes marked with SYSLINUX, PXELINUX, ISOLINUX |
|
or EXTLINUX apply to that specific program only; other changes apply |
|
to all derivatives. |
|
|
|
Changes in 6.03: |
|
* chain: Fix chainloading on 6.02 (Raphael S. Carvalho). |
|
* core: Do not leak the __lowmem and __bss16 macros to modules; |
|
hide them so modules will not use them. |
|
* load_linux: Do not use size heuristic for non-relocatable |
|
kernels, for zImage kernels and for non-Linux kernels. |
|
* PXELINUX: Fix the SENDCOOKIES feature for HTTP |
|
(Russel Santillanes). |
|
* gnu-efi: Add gnu-efi as a submodule. |
|
* ANSI: Support color tables with more than 256 entries |
|
(James Buren). |
|
* EFI: Fix displayed version; add DATE (Gene Cumm) |
|
* PXELINUX, EFI: Fix bad read of file size over TFTP on EFI64 |
|
(Sylvain Gault). |
|
* Fix hand over to kernel: |
|
"Booting kernel failed: Invalid argument" error. |
|
* ISOLINUX: EDX, LBA values higher than 65535; work around for |
|
buggy BIOS, where the system would hang, would reboot, or |
|
would show a "Disk error 01, AX=42" message. |
|
* core/legacynet: Enable dot quad resolution (Gene Cumm). |
|
* diag/geodsp improvements (Gene Cumm). |
|
* DOS: Fix syslinux.com DOS-based installer. |

|
* syslxint: fix compilation on non-x86 architectures. |
|
* localboot: Fix "localboot 0x80" and similar cases. |
|
* Add memset() calls prior to any intcall() and other mem fixes; |
|
specially relevant for older hardware and/or buggy BIOS. |
|
* poweroff.c32: Fixes (Gene Cumm). |
|
* HDT: Fix memory leak in CLI (Felipe Pena). |
|
* ACPI: Remove memset of buffer; it makes things clearer but |
|
also prevents some compilation warnings (Erwan Velu). |
|
* Add manpages for isohybrid, memdiskfind |
|
(Peter Jones, Gene Cumm). |
|
* ISOLINUX: Experimental Rock Ridge support (Thomas Schmitt). |
|

|
(Sylvain Gault, Gene Cumm). |
|
* BIOS: Fix low memory check. |
|
* Filesystem UUID to SYSAPPEND bit 0x40000 for FAT and ext2 |
|
(Serj Kalichev). |
|
* Makefiles: Export the firmware type as a cpp variable. |
|
Additional improvements. Fix "make spotless". |
|
* core, BIOS: Move __syslinux_shuffler_size to assembly. |
|
Actually get the shuffler size sanely. Fix booting recent |
|
Syslinux versions on certain hardware and on certain |
|
virtualization software (e.g. QEMU 0.11.1, VirtualBox 4.1.x). |
|
* lua: Upgrade to v.5.2.3 (Ferenc Wágner) and additional fixes. |
|
* chainload: Fixes to chain.c32 and pxechn.c32. |
|
* NTFS: Make byte_shift a constant. |

|
(Raphael S. Carvalho). |
|
* NTFS: Handle fragmented $MFT file (Andy Alex). |
|
* BIOS: Use int 0x16, ah=0x02 to probe for shift flags. Attempt |
|
workaround for USB keyboards not responding at boot time. |
|
* kbd: Getting the keyboard shift state is now a firmware method. |
|
* kbd: Fix force-prompt features. |
|
* BTRFS: Fix booting on BTRFS. |
|
* cache, btrfs: Provide a general cached read routine. |
|
* NTFS: Correct file->offset usage in ntfs_readdir (Andy Alex). |
|
* New support for UFS/FFS (UFS1/2) (Raphael S. Carvalho). |
|
* adv: Remove double definition; |
|
it should fix uses of the ADV, including "--once". |
|
* memdump: Remove old obsolete COM16 binary. |
|
* isohybrid: Numerous fixes (Thomas Schmitt). |
|
* chain.c32: Add an adjustable "strict={0,1,2}" flag, improve |
|
error reporting (Michal Soltys.) |
|
* lpxelinux.0: Workaround for various buggy BIOSes (Gene |
|
Cumm.) |
|
* PXE: Fix a stack-smashing bug which broke a large number of |
|
systems. |
|
|
|
Changes in 6.02: |
|
* efi64: Add support for booting 32-bit kernels. |
|
* efi: Use the EFI handover protocol when booting kernels if |
|
available. |
|
* Fix various make targets that became broken when switching to |
|
per-firmware object directories, including 'make install' and |
|
'make netinstall'. |
|
* efi: Improve handling of packet loss in UDP stack. |
|
* tests: Introduce a new regression test framework designed to |
|
ensure bugs are not reintroduced once fixed. |
|
* efi: Implement localboot support. |
|
|
|
Changes in 6.01: |
|
* efi: Mark some symbols as __export otherwise libcom32.c32 and |
|
vesamenu.c32 will refuse to load. |
|
* bios: Wire up the bios kernel loader. It was impossible to |
|
load a kernel from bios in 6.00. |
|
* efi: Fix 'make installer'. There are no EFI installers so |
|
don't try and build them as we run into build errors. |
|
* efi: Reuse the initial TFTP client port in subsequent |
|
transfers otherwise the server will send an error packet. |
|
* efi: Some firmware will not set a default TTL value in IP |
|
packets - we must explicitly set it ourselves otherwise a |
|
value of zero may be used. |
|
* bios, font: Fix a font regression affecting some VirtualBox |
|
users. |
|
|
|
Changes in 6.00: |
|
* Add support for booting from EFI. |
|
* EFI TCP/IP support. This allows the EFI backend to hook into |
|
the generic TFTP, HTTP and FTP functionality. |
|
|
|
Changes in 5.11: |
|
* Dynamic debug support: Add new module, debug.c32, that allows |
|
debug code to be dynamically enabled and disabled at runtime. |
|
|
|
Changes in 5.10: |
|
* PXELINUX: An entirely new network implementation based on |
|
the lwIP embedded TCP/IP stack. As a result, plain PXELINUX |
|
can now support HTTP and FTP without gPXE/iPXE. ls/readdir |
|
functionality is supported over HTTP with an indexing |
|
webserver, or over FTP with most common FTP servers. For the |
|
new network stack use lpxelinux.0. For the legacy stack use |
|
pxelinux.0. |
|
* Rename the "ipappend" option to "sysappend" ("ipappend" is |
|
still accepted as an alias) and make it available for all |
|
derivatives. Add additional strings derived from the system |
|
DMI/SMBIOS information if available. |
|
* "sysappend" strings are also sent as http cookies, with the |
|
prefix _Syslinux_ added, on all http transfers. This can be |
|
overridden with the SENDCOOKIES configuration file command. |
|
* poweroff.c32: A new module to power off a system via APM. It |
|
replaces the poweroff COMBOOT module (Sebastian Herbszt). |
|
* PXELINUX: Fix booting with DHCP options 209 and 210 which was |
|
broken in 5.00. |
|
* Handle loading kernel images with no protected mode code. A |
|
legitimate kernel image can consist solely of real-mode code. |
|
The support for booting such images was broken in 5.00 (Josh Triplett). |
|
* Fix a regression in the .psf font file loader introduced |
|
in 5.00. |
|
|
|
Changes in 5.01: |
|
* txt/: A new AsciiDoc documentation set (work-in-progress) |
|
(Gene Cumm). |
|
* core: Fix a bug in the realloc() implementation that caused |
|
machines to appear to run out of free memory. |
|
* ldlinux: Fix multiple buffer overflows in cmdline parsing |
|
code that resulted in files failing to run and cmdlines |
|
being truncated. |
|
* core: Fix debug build by tagging __bad_SEG() with __export. |
|
* com32: Restrict library filenames to 8.3 format. |
|
* EXTLINUX: Fix installation and subdirectory patching. |
|
* ISOLINUX: Fix booting isohybrid images that are over 32K. |
|
* com32: Strip modules to reduce their size. |
|
* XFS: Implement directory block cache and fix |
|
shortform-directory lookup (Paulo Alcantara). |
|
|
|
Changes in 5.00: |
|
* com32: Switched from the COM32 object format to ELF as it is |
|
a much more powerful format that allows undefined symbols to |
|
be resolved at runtime and dynamic loading of module |
|
dependencies, which means modules now become shared object |
|
files instead of statically linked binaries - reducing both |
|
disk space and runtime memory consumption. |
|
* core: Split non-core functionality into ldlinux.c32, which |
|
is an ELF module loaded by the core that contains everything |
|
the core doesn't require to boot the system, e.g. config |
|
parser, command-line interface, etc. |
|
* Replaced __intcall() calls with direct function calls now |
|
that we can resolve undefined symbols at runtime, thanks to |
|
the ELF object support. Now that we no longer need to go |
|
through the 16-bit interrupt mechanism we can make full use |
|
of the 32-bit execution environment. This change required |
|
reimplementing lots of the 16-bit assembly code from core/ |
|
in C. |
|
* com32: __com32.cs_bounce is gone now we always run in a |
|
32-bit environment once we execute ldlinux.c32. |
|
* ldlinux: A new "PATH" directive was added to the ldlinux.c32 |
|
config parser that specifies a colon-separated list of |
|
directories to search when attempting to load modules. |
|
* ALL: Delete all references to/code for 16-bit COMBOOT files. |
|
COMBOOT files (.cbt and .com) are no longer supported under |
|
Syslinux. |
|
|
|
Changes in 4.07: |
|
* EXTLINUX: fix crash caused by dereferencing garbage pointer. |
|
* Plug memory leak in searchdir which eventually leads to an |
|
observable hang (Shao Miller). |
|
* ISOLINUX: fix bug triggered by isohybrid images larger than |
|
32K which results in an invalid image checksum error. |
|
* menugen: make it Py3k compatible (Paulo Alcantara). |
|
|
|
Changes in 4.06: |
|
* Support for NTFS, by Paulo Alcantara. |
|
* EXTLINUX: more robust device detection, allow user to override. |
|
* kontron_wdt.c32: Add a new module to enable the hardware |
|
watchdog of some Kontron boards. It allows enabling the watchdog |
|
and then booting a given image. |
|
* HDT updated, and now can display images regarding some detection |
|
steps. Add postexec command to run a particular entry after |
|
HDT's execution, add silent option and various fixes. |
|
* ifcpu.c32: Detect hypervisor presence. |
|
* lua.c32: Add dhcp support and support for native Syslinux |
|
functions syslinux_config(), syslinux_ipappend_strings() and |
|
syslinux_reboot(). |
|
* isohybrid: Workaround for various EFI systems. |
|
* pxechn.c32, a PXE NBP chainloader. More versatile alternative |
|
to pxechain.com and resolves the PXELINUX -> WDS issue with |
|
Microsoft Windows Server 2008R2 (Gene Cumm). |
|
* btrfs: Fix booting off of a subvolume. |
|
* com32: Add device tree support. |
|
* SYSLINUX: Fix relative paths for VFAT. The CONFIG and APPEND |
|
directives now support entirely relative paths. |
|
|
|
Changes in 4.05: |
|
* HDT updated, and now supports uploading data to a TFTP |
|
server. |
|
* ISOLINUX: remove the .img file support; it has been broken |
|
on virtually all systems since the beginning, and has been |
|
totally broken since 4.00 at least. Use MEMDISK instead. |
|
* chain.c32: Support chaining ReactOS' FreeLdr (Shao Miller) |
|
* isohybrid: -m option to add support for Mac EFI booting. |
|
* ifmemdsk.c32: Choose boot option based on presence of |
|
MEMDISK. |
|
* Remove bogus distributed mk-lba-img binary. |
|
* The Syslinux project has a new, cool logo by Abi |
|
"ixxvil" Rasheed (doc/logo/*). |
|
|
|
Changes in 4.04: |
|
* PXELINUX: Fix handling of unqualified DNS names. |
|
* PXELINUX: Fix timer bug when PXELINUX might be unloaded |
|
(Gene Cumm). |
|
* core/writedec.inc: Fix duplicate declaration and overflow |
|
(Gene Cumm). |
|
* GCC 4.5 fixes. |
|
* sample directory: Fix Makefile include (Gene Cumm). |
|
* ver.com: New universal DOS/COMBOOT application to display |
|
version information (includes DRMK) (Gene Cumm). |
|
* rosh.c32: updated; Using getopt() for internal commands to aid |
|
parsing options; Fix bugs in ls; add warm reboot and echo |
|
(Gene Cumm). |
|
* com32: fix a file descriptor leak. |
|
* gfxboot.c32: handle TEXT..ENDTEXT; error out on no LABELs |
|
found (Sebastian Herbszt). |
|
* Fix booting on non-partitioned devices. |
|
* MBR, isohybrid: Workaround for a BIOS issue on Acer |
|
Travelmate and possibly other machines. |
|
* COM32: Adding ACPI parsing libary |
|
* HDT: Release 0.4.1 to support ACPI parsing, |
|
improved mutli-core/cpu reporting |
|
* LUA: Updating to 5.1.4-2 |
|
* SYSLINUX: core/diskstart.inc: Reset DS after checksum in case |
|
it isn't 0 (Gene Cumm). |
|
* win64: Script update for additional mingw compiler names |
|
(Gene Cumm). |
|
* diag: New directory for diagnostic-related tools. Add a |
|
handoff MBR/VBR and geometry display images (Gene Cumm). |
|
* MEMDISK: use "mem=" parameter to mark available memory above |
|
this point as reserved (core already does alignment) (Gene Cumm). |
|
* MEMDISK: Additional disk probe checks and debug output |
|
(Shao Miller, Gene Cumm). |
|
* gpxe: add gpxelinuxk.0, based off of undionly.kpxe + new |
|
script (Gene Cumm). |
|
* isohybrid: install the isohdpfx*.bin/isohdppx*.bin files to |
|
make isohybrid images in one step with GNU xorriso. |
|
* PXELINUX: disable a hack that would make localboot work on |
|
some machines, but break just about as many. Some machines |
|
which worked with "localboot 0" in previous versions may |
|
need "localboot -1" in this one. If you have a machine |
|
which requires "localboot -1", a copy of the dmidecode |
|
or sysdump output would be appreciated. |
|
* Include a set of diagnostics by Gene Cumm. |
|
* Fixes for gcc 4.6 and binutils 2.21.51. |
|
* chain.c32: Allow "uuid" as a synonym to "guid". |
|
* Handle directory names starting with .. for vfat and |
|
iso9660. |
|
* New MENU HIDDENKEY command to provide a one-keystroke way to |
|
activate a boot option from a hidden menu intro screen. |
|
|
|
Changes in 4.03: |
|
* Don't hang if no configuration file is found. |
|
* Better support for booting from MBRs which don't pass |
|
handover information. |
|
* EXTLINUX: Try to be smarter about finding the partition |
|
offset. |
|
* chain.c32: support chainloading Dell Real Mode Kernel (Gene |
|
Cumm). |
|
* chain.c32: fix booting in CHS mode. |
|
* rosh.c32 updated (Gene Cumm). |
|
* Fix the -s option to the syslinux/extlinux installer (Arwin |
|
Vosselman). |
|
* isohybrid: fix padding of large images (PJ Pandit). |
|
|
|
Changes in 4.02: |
|
* SYSLINUX: correctly handle the case where the -d option is |
|
specified with a non-absolute path, i.e. "syslinux -d |
|
syslinux" instead of "syslinux -d /syslinux". |
|
* ISOLINUX: recognize the directory names /boot/syslinux and |
|
/syslinux, and the filename syslinux.cfg in addition to the |
|
isolinux-specific names. Thus, "syslinux.cfg" is now a |
|
generic name, whereas "isolinux.cfg" or "extlinux.conf" is |
|
specific to different derivative. |
|
* chain.c32: support setting alternate config filename for |
|
stage2 of GRUB Legacy (Gert Hulselmans). |
|
* whichsys.c32: execute specific command, based on Syslinux |
|
bootloader variant (Gert Hulselmans). |
|
* lua.c32: a lot of new bindings added to the "syslinux" |
|
namespace: VESA, PCI, DMI, kernel loading (Marcel Ritter). |
|
* btrfs: print a comprehensive error message if compressed or |
|
encrypted files are encountered (neither is currently |
|
supported.) |
|
* SYSLINUX: mtools installer: honor TMPDIR, error out on disk |
|
full. |
|
* Handle fallbacks from EDD to CHS, to deal with systems which |
|
announce EDD support but don't actually have it. |
|
* SYSLINUX: the mtools, DOS and win32 installers now use the new |
|
command line options. |
|
* PXELINUX: fix the use of IP addresses in TFTP :: or tftp:// |
|
host syntax. |
|
* SYSLINUX: experimental Win64 installer (syslinux64.exe). |
|
|
|
Changes in 4.01: |
|
* ISOLINUX: fix initialization on systems which don't zero |
|
low memory. |
|
* SYSLINUX/EXTLINUX: fix handing of disk read retries in |
|
EDD mode. |
|
* ISOLINUX: change the initialization sequence to avoid |
|
problems with certain (old) BIOSes. Special thanks to |
|
Helmut Hullen for invaluable debugging support. |
|
* ifplop.c32: new module which detects if the PLoP Boot Loader |
|
already has booted a CDROM or USB drive (Gert Hulselmans). |
|
* Correct a severe memory overwrite bug, triggered primarily |
|
when selecting a very long command line in the menu system. |
|
* lua.c32: Lua script interpreter, currently experimental |
|
(Alexey Zaytsev, Marcel Ritter, Geert Stappers). |
|
* PXELINUX: new option IPAPPEND 4 to append the system UUID to |
|
the kernel command line. |
|
* PXELINUX: display BOOTIF and SYSUUID at startup time, and |
|
when Ctrl-N is pressed on the command line. |
|
|
|
Changes in 4.00: |
|
* Major code base changes; all filesystem rewritten in C. |
|
This work was done primarily by Liu Aleaxander (Yuanhan Liu). |
|
* EXTLINUX: btrfs and ext4 support. btrfs support was done by |
|
Alek Du of Intel. |
|
* EXTLINUX is no longer a separate derivative; extlinux and |
|
syslinux both install the same loader (ldlinux.sys); for the |
|
Linux-based installers the extlinux binary is used for a |
|
mounted filesystem; the syslinux binary for an unmounted |
|
filesystem. |
|
* When loading a new configuration file with the CONFIG |
|
command, one can now also specify a new current directory |
|
with an APPEND statement. |
|
* Full ADV support for Syslinux, to boot-once and MENU SAVE |
|
works. |
|
* Full support of GPT-partitioned disks, including disks |
|
and/or parititions larger than 2 TiB (if supported by BIOS.) |
|
* The GPT handover protocol adjusted to the current T13 |
|
committee draft; see doc/gpt.txt. |
|
* HDT: code cleanup, small bugfixes |
|
* The "linux" syslinux installer (syslinux-nomtools) now has a |
|
command-line syntax closer to the extlinux installer. The |
|
mtools, dos and win32 installers will get this new syntax |
|
eventually, but it is not implemented yet. |
|
* chain.c32: support booting GPT partitions by index, GUID, label. |
|
* chain.c32: support booting the Syslinux partition with "fs". |
|
* chain.c32: implement gpt.txt hand-over protocol. |
|
* chain.c32: support for chainloading Grub stage 2. |
|
* PXELINUX: TFTP URL syntax (tftp://) supported even when not |
|
running gPXE/gpxelinux. |
|
* New ls.c32 module to display the contents of the disk from |
|
the command line, and pwd.c32 to display the current |
|
directory. |
|
* rosh.c32 (read only shell) updated and hopefully usable. |
|
* PXELINUX: Support "localboot -1", just like the other |
|
derivatives. |
|
* gfxboot.com removed in favor of gfxboot.c32. |
|
* New MENU HELP statement to display fullscreen help text as a |
|
result of a menu selection. |
|
* memdiskfind utility that can be used with the phram driver |
|
in the Linux kernel to mount a memdisk. |
|
* ifcpu.c32: Adding usage when no parameters are given, |
|
adding PAE support. |
|
* ifcpu.c32, ifcpu64.c32: handle more than one argument per |
|
target. |
|
* isohybrid: C version which does not require Perl. |
|
* New command MENU IMMEDIATE to permit hotkeys to activate |
|
immediately without needing Enter. |
|
* mdiskchk.com supports a --no-sequential (or -n) option to |
|
suppress the classic all-drive-probing heuristic. Useful |
|
on BIOSes who crash/hang when certain drive numbers are |
|
probed. |
|
* ElTorito.Sys DOS driver now scans drive numbers upwards |
|
instead of downwards, in order to avoid a fairly common |
|
bug on some BIOSes where probing drive 0xFF causes a |
|
failure. |
|
* NASM 2.03 or later required to build. 2.07 or later |
|
recommended. |
|
|
|
Changes in 3.86: |
|
* chain.c32: fix chainloading the MBR of a hard disk (broken |
|
in 3.85). |
|
* mboot.c32: report the boot loader name in the information |
|
structure. |
|
* com32: set argv[0] in a com32 module. |
|
* core: add a workaround for a bug in Xen HVM older than |
|
version 3.3: disable halt on those platforms. |
|
* Fix problems where certain operations in com32 modules would |
|
cause the core to believe the system was idle. |
|
* MEMDISK: fix MBR detection when used with a DOSEMU header or |
|
an offset. |
|
* MEMDISK: generate the mBFT checksum correctly. |
|
|
|
Changes in 3.85: |
|
* gPXELINUX: updated to gPXE 1.0.0. gPXELINUX can now do NBP |
|
chainloading, and does not require a second DHCP. |
|
* vesamenu.c32: unbreak the default "grey hole" background. |
|
* We no longer have a built-in default of "linux auto". |
|
Instead, if no DEFAULT or UI statement is found, or the |
|
configuration file is missing entirely, we drop to the boot: |
|
prompt with an error message (if NOESCAPE is set, we stop |
|
with a "boot failed" message; this is also the case for |
|
PXELINUX if the configuration file is not found.) |
|
* chain.c32: support chainloading Grub4DOS; patch by Gert |
|
Hulselmans. |
|
* New tool: sysdump.c32, can be used to produce system |
|
information for debugging via tftp or ymodem (serial port). |
|
* "vga=current" on the Linux command line is now supported. |
|
* chain.c32: support for Windows Recovery Console, via the |
|
"cmldr=" option. |
|
* chain.c32: should now support loading NTLDR from different |
|
type media than loaded from. |
|
* chain.c32: support chainloading to a FAT/NTFS partition with |
|
invalid "hidden sectors" via the "sethidden" option. |
|
* memdisk: fix the mBFT ACPI table. |
|
* vesamenu.c32: if the image is smaller than the screen, tile |
|
it across the whole screen. |
|
* mkdiskimage: -s option for producing a sparse image. |
|
* vesamenu.c32: support arbitrary resolution setting (beyond |
|
BIOS support) on some Intel-based video chipsets. This code |
|
is a modified version of the "915resolution" tool by |
|
Steve Tomljenovic; your mileage might vary. |
|
|
|
Changes in 3.84: |
|
* SYSLINUX: make the DOS installer work for MS-DOS 7.x/8.x |
|
(Win9x/ME) again. |
|
* HDT: updated to version 0.3.6 (numerous changes.) |
|
* mboot.c32: now supports video mode setting if requested by |
|
the image. |
|
* MEMDISK: Fix floppy images of PC-DOS. |
|
* MEMDISK: Add support for emulation of CD-ROM images; patch |
|
by Shao Miller. |
|
* MEMDISK: Comply with the Win9x "safe hook" standard, |
|
allowing a protected-mode driver. |
|
* MEMDISK: New "mBFT" ACPI table, by analogy with the iSCSI |
|
iBFT table. This allows detection from a protected-mode |
|
operating system without EDD support. |
|
* 32-bit version of the gfxboot loader (gfxboot.c32), so far |
|
experimental. This will replace gfxboot.com in the future. |
|
* vesamenu.c32: new MENU RESOLUTION directive to set a screen |
|
resolution other than 640x480. |
|
* chain.c32: add support for loading isolinux.bin. |
|
* chain.c32: make sure to always return to text mode. |
|
* eltorito.sys: DOS driver for generic CD-ROMs; by Gary Tong |
|
and Bart Lagerweij. |
|
|
|
Changes in 3.83: |
|
* PXELINUX: clear memory before handing over to a chainloaded |
|
NBP. This may help avoid a bug in Windows RIS. |
|
* PXELINUX: fix localboot after NBP chainloading on certain |
|
BIOSes (including ASUS A8N-E, but possibly others.) |
|
* chain.c32: support chainloaded bootloaders on ISOLINUX. |
|
* PXELINUX: allow filenames up to 251 characters. |
|
* MEMDISK: fix problems booting from USB on Thinkpads, and |
|
possibly other machines or hardware combinations. |
|
* isohybrid: fix the -id option. |
|
* HDT: updated to version 0.3.4. |
|
* MEMDISK: the stack size is now configurable, with the stack= |
|
option. |
|
* Simple menu: fix Ctrl-W (word erase) in command-line edit. |
|
* Simple menu: fix crash on some platforms. |
|
* Gfxboot: fixes to the configuration file parsing. |
|
* PXELINUX: add a tool to override specific DHCP options via |
|
values hardcoded in the pxelinux.0 file. These hardcoded |
|
values can be either "before DHCP" (defaults if DHCP do not |
|
provide values), or "after DHCP" (overrides DHCP). The tool |
|
pxelinux-options can be used to set these options. This |
|
feature does not apply to gpxelinux.0; when used with gPXE |
|
this is better handled by modifying the embedded script. |
|
|
|
Changes in 3.82: |
|
* isohybrid: fix the -partok logic for loading from a partition. |
|
* ISOLINUX: deal with systems which return from INT 13h with |
|
interrupts disabled. |
|
* Do not invoke the idle handler during large file loads. |
|
* Simple menu: make ONTIMEOUT work with MENU HIDDEN. |
|
* PXELINUX: handle TFTP servers which have extra NULs at the |
|
end of an OACK packet. |
|
|
|
Changes in 3.81: |
|
* Shuffler: fix bug in real-mode entry. This affected a |
|
number of modules, probably in relatively unimportant ways, |
|
but it completely broke linux.c32. |
|
* Improved performance. |
|
* Attempt to halt the processor while idle. This can cause |
|
bad reponsiveness when using a serial console especially for |
|
automated input; if that ends up being a problem, use the |
|
new "NOHALT 1" configuration command. |
|
* linux.c32 now suppresses all messages if the "quiet" flag is |
|
specified. |
|
* isohybrid: add a variety of options, and a help message. |
|
* ISOLINUX: fix booting in hybrid mode when CBIOS is used. |
|
This unfortunately means that the isohybrid handoff protocol |
|
has changed, so the isohybrid utility must version-match |
|
isolinux.bin. |
|
* Drop support for ACPI 3 extended memory flags. |
|
* Menu system: don't set the autocr flag on the serial |
|
console. |
|
* altmbr: fix handling of logical partitions. |
|
* altmbr: cap at 439 bytes so the partition select byte isn't |
|
part of the file. |
|
|
|
Changes in 3.80: |
|
* New shuffler mechanism and API. |
|
* Rewritten mboot.c32 module. |
|
* The syslinux_boot_linux() function has been simplified. |
|
* Don't hang trying to boot a "menu quit" label from the CLI. |
|
* Fix problem with boot-once "sticking" on some BIOSes. |
|
* isohybrid: fix problem with images over 2 GB in size. |
|
* APM poweroff module (poweroff.com) by Sebastian Herbszt. |
|
* ISOLINUX: fix the handling of large directories. Bug found |
|
and fixed by Steffen Winterfeldt. |
|
|
|
Changes in 3.75: |
|
* PXELINUX: fix the "keeppxe" option, which was broken in |
|
3.74. |
|
* MEMDISK: correct the extraction of geometry information from |
|
the MBR of a hard disk image, again broken in 3.74. |
|
* extlinux(1) man page from Brian Pellin. |
|
* Simple menu: MENU SAVE is now controllable on a menu-by-menu |
|
or entry-by-entry basis. |
|
* gPXELINUX: fix interrupt-disabling bug. |
|
* HDT: fix lockup on machines with certain PCI configurations. |
|
|
|
Changes in 3.74: |
|
* New UI directive, which allows a more natural way to specify |
|
a menu system (or not.) With the UI directive specifying |
|
the menu system, the DEFAULT directive can be used to select |
|
the default entry inside the menus. |
|
* kbdmap.c32: new module to load a new keyboard map |
|
dynamically. |
|
* isohybrid: workaround bug in some versions of binutils. |
|
* Fix issue with the placement of the initrd on some machines. |
|
* ifcpu64: fix handling of less than three arguments. |
|
* Fix bug in the shuffle library when dealing with a very |
|
large number of fragments. |
|
* Documentation fixes by Vicente Jimenez Aguilar. |
|
* gPXE updated to version 0.9.7. |
|
* hdt.c32: Hardware Detection Tool, an interactive hardware |
|
analyzer module by Erwan Velu. |
|
* MEMDISK: enable automatic determination of the disk geometry |
|
for a large floppy disk image if (and only if) it is |
|
formatted with a FAT filesystem. |
|
* SYSLINUX: fix the handling of .bss files on FAT12/16. |
|
* Suppress the Loading ... message if "quiet" is specified on |
|
the kernel command line. |
|
* Fix the use of "CONSOLE 0" with menu.c32. |
|
* Allow COM32 modules to be aware of all memory even in the |
|
presence of a memory hole. The "linux.c32" module can be |
|
used to load a kernel (or memdisk) plus large initrd on |
|
such a system. |
|
* MBR: produce alternate MBR variants which force the drive |
|
number to hd0 (_f variants), or force the drive number to |
|
hd0 if the Ctrl key is pressed (_c variants.) Furthermore, |
|
add an MBR variant (altmbr*.bin) which ignores the active |
|
flag and instead boots the partition number specified in the |
|
byte at offset 439 decimal. |
|
* Add IPAPPEND strings to com32 modules, especially needed for |
|
linux.c32. |
|
* New MENU SAVE directive which saves the latest menu |
|
selection until the next boot. Currently only implemented for |
|
EXTLINUX. |
|
* gfxboot.com: *experimental* interface module to Steffen |
|
Winterfeldt's "gfxboot" graphical front end |
|
(http://gfxboot.sourceforge.net/). Module by Sebastian Herbszt. |
|
|
|
Changes in 3.73: |
|
* Upgrade gPXE to release version 0.9.5. |
|
* Fix a number of build errors on various platforms. |
|
* Handle systems with E820 "extended attributes" per ACPI 3. |
|
Someone "cleverly" decided to change the E820 spec in a |
|
backwards-incompatible manner! |
|
* MEMDISK: default to "safeint". |
|
* Adopt the moniker "The Syslinux Project", standard proper |
|
noun capitalization, to refer to the project as a whole. |
|
Thus, reserve the all-caps "SYSLINUX" to refer to the FAT |
|
loader. |
|
* mboot.c32: add "-solaris" option to pass DHCP information to |
|
the Solaris kernel; required for automatic Solaris boot |
|
without using Solaris' pxeboot program. |
|
* config.c32: trivial COM32 module to restart Syslinux with |
|
another configuration file from the command line (equivalent |
|
to the CONFIG command in the configuratin file.) |
|
|
|
Changes in 3.72: |
|
* Include the pxechain.com module from Jeffery Hutzelman at |
|
Carnegie Mellon University. This allows chaining another |
|
PXE boot program while changing the DHCP packet passed to |
|
it. |
|
* Reorganize the Makefile system. |
|
* Major PCI core cleanups and other source cleanup. |
|
* gPXE code updated. |
|
* Try to avoid memory-snooping attacks on passwords. Note |
|
that if someone has root on the box, they generally don't |
|
need to compromise the boot loader... |
|
* ISOLINUX: fix crash when given a zero-length file. |
|
* sdi.c32: support gzipped SDI images. |
|
* ISOLINUX: support generating images which can be either |
|
a CD-ROM or a hard disk (USB disk, etc.) See |
|
doc/isolinux.txt for more information. |
|
* Remote gdb support for COM32 modules; patch from Stefan |
|
Hajnoczi. |
|
* Support beeps in F-key help in the simple menu system. |
|
* Tab display of labels, based on a patch from Sebastian |
|
Herbszt. Can be disabled with the NOCOMPLETE configuration |
|
command. |
|
* "menu default" can now be specified after "menu begin", to |
|
indicate that a specific submenu should be the default entry. |
|
|
|
Changes in 3.71: |
|
* Workaround for a VESA BIOS which tries to make DOS system |
|
calls(!!) |
|
* Simple menu: fix navigation around disabled entries |
|
(or at least try to...) |
|
* EXTLINUX: proper error message when confused about mount |
|
point. |
|
* MEMDISK: be smarter about incompletely disabled floppies in |
|
the BIOS and about being the only floppy. |
|
* Optionally allow initrd to be specified on a separate line |
|
rather than as part of the "append" line. This is not |
|
recommended, but apparently makes life easier for some |
|
tools. |
|
* SYSLINUX: if no config file is present, set the current |
|
directory to the root directory (Sebastian Herbszt). |
|
* chain.c32: option "hide" to support hiding and unhiding of |
|
primary partitions on the boot drive with DOS, Win, or OS/2 |
|
partition types (01, 04, 06, 07, 0b, 0c, 0e). |
|
* Unbreak the KBDMAP command (broken in 3.70). |
|
* EXTLINUX: fix the handling of the ADV when using CBIOS. |
|
* ifcpu64.c32: simple COM32 module to select a 32- or 64-bit |
|
kernel (and optionally 32-bit kernels with or without PAE.) |
|
Eventually we want a scripting language for this |
|
kind of stuff; a Lua module is under development. |
|
* Fix parsing of the SERIAL command without a baud rate |
|
specified. |
|
* chain.c32: error out when try to boot an unbootable |
|
partition. |
|
* SYSLINUX: when building the Win32 installer, search for |
|
MinGW under a large number of possible names. |
|
|
|
Changes in 3.70: |
|
* PXELINUX: Support enhanced capabilities when running on top |
|
of gPXE (http://www.etherboot.org/). In particular, support |
|
URL-style syntax for filenames, and any protocol that gPXE |
|
supports (except, currently, iSCSI and AoE.) This feature |
|
is currently highly experimental. |
|
* Substantial infrastructure changes to support files whose |
|
length aren't known at open time (typically network |
|
connections.) Please note that the semantics of some of the |
|
comboot APIs have changed slightly; please see doc/comboot.txt. |
|
* PXELINUX: We no longer require a TFTP server which supports |
|
the tsize option for all transfers. |
|
* PXELINUX: Integrate with the gPXE source base; unified image |
|
now included as "gpxelinux.0". |
|
* The source tree has been restructured; files that were |
|
previously in the root have moved into the core, dos, gpxe, |
|
and utils directories. |
|
* "make install", "make netinstall", and "make extbootinstall" |
|
have been updated massively. "make install-all" now installs |
|
all three. |
|
* Change default dir for auxiliary files from |
|
/usr/lib/syslinux to /usr/share/syslinux. |
|
* SYSLINUX: VFAT long filename support. |
|
* MEMDISK: Any image less than 4096K (4 MB) is treated as a |
|
floppy disk. The geometry-guessing code will recognize all |
|
common extended formats, but it is still possible some very |
|
exotic formats need geometry specification. Large floppies |
|
and very small harddisks still need explicit specification. |
|
* chain.c32: option "swap" to support swapping of BIOS drive |
|
numbers. This is necessary to boot certain operating systems |
|
(DOS, Windows) from a secondary drive. |
|
* chain.c32: option "file=" to support loading a boot file from |
|
the SYSLINUX filesystem instead of loading the boot sector |
|
from the drive. |
|
* chain.c32: option "seg=" to control the load location. |
|
* chain.c32: option "ntldr=" as a shorthand for "seg=0x2000 |
|
file="; use this to load one of WinNT's loaders: |
|
|
|
chain.c32 hd0 1 ntldr=/MiniNT/setupldr.bin |
|
|
|
Note that the file needs to be in the SYSLINUX filesystem. |
|
* chain.32: options "freedos=" and "msdos="/"pcdos=" as |
|
shorthands for "seg=0x60 file=" and "seg=0x70 file=" |
|
respectively; use this to load FreeDOS's kernel.sys, MS-DOS's |
|
io.sys or PC-DOS's ibmbio.sys. |
|
* Change to the A20 algorithm which *MIGHT* help systems that |
|
have systems which freeze when Syslinux is used with USB |
|
keyboards. Note that this has been hard do verify, so I |
|
would greatly appreciate feedback on it. |
|
* Complex menu system: unbreak menus which has unnamed |
|
submenus, like complex.c. |
|
* Fix newline on the serial port for some com32 modules. |
|
* chain.c32: support "boot" as the drive specification, |
|
indicating the drive from which it was booted |
|
(for syslinux/extlinux). |
|
* SYSLINUX/EXTLINUX: support "localboot" with the same feature |
|
set as ISOLINUX. |
|
* Add an experimental MBR for GPT partition tables. |
|
* Use $(CC) when determining compile flags. |
|
* chain.c32: fix booting from logical partitions (Sergey |
|
Vlasov.) |
|
|
|
Changes in 3.63: |
|
* Fix errors in the PCI and DMI detection modules (Erwan Velu, |
|
Sebastian Herbszt). |
|
* Fix host dependencies and other issues in the build system. |
|
* PXELINUX: Allow class E addresses as unicast. |
|
* sdi.c32: module to load Microsoft System Deployment Images. |
|
For additional information, please see: |
|
http://msdn2.microsoft.com/en-us/library/ms838543.aspx |
|
* EXTLINUX: Correct reading directories with deleted entries. |
|
* Shuffle library: correct the handling of certain geometries |
|
(an upward move with source material blocking the move); as |
|
required by sdi.c32 but theoretically possible for other |
|
formats as well. |
|
* Add "make netinstall" to install /tftpboot. |
|
* Fix some documentation files that didn't get moved/renamed. |
|
|
|
Changes in 3.62: |
|
* Clean up garbage after "aborted." message. |
|
* Clean up memdump.com filenames. |
|
* Support SHA256 and SHA512 encrypted passwords. |
|
* The shuffle library now can generate chained descriptors, |
|
thus allowing pretty much arbitrarily complex memory maps. |
|
* Handle command lines up to 2047 characters, the current |
|
Linux kernel limit. |
|
* vesamenu: support systems without linear framebuffer support |
|
(sigh, what is this, 1993?) and 15-bit RGB modes. |
|
* Move the label storage (for the command-line interface) to |
|
high memory, removing the size limit and freeing up 64K of |
|
low memory. |
|
* Get rid of 4096-entry limit in the simple menu system. |
|
* New hierarchial submenu support: see MENU BEGIN, MENU END, |
|
MENU GOTO in doc/menu.txt. |
|
* MENU QUIT allows creating a menu entry for returning to the |
|
command line. |
|
* ISOLINUX: Work around bug in certain Adaptec BIOSes, |
|
patch by Bruce Robson. |
|
* pngtopnm dependency removed from samples/ directory. |
|
* Text documentation files (in doc/) renamed *.doc -> *.txt. |
|
|
|
Changes in 3.61: |
|
* EXTLINUX: fix crash when accessing an empty file. |
|
* elf.c32: If a PHDR segment is present, load it. |
|
* Fix SHA-1 and MD5 passwords. |
|
* ISOLINUX: fix booting when mastered without |
|
mkisofs -boot-info-table (broken since 3.50, sigh...) |
|
* Handle BIOSes which emit multiple contiguous valid |
|
memory regions in the e820 map. |
|
|
|
Changes in 3.60: |
|
* Support for "auxilliary data vector", a small amount of |
|
writable storage. Currently only supported for EXTLINUX, |
|
but the infrastructure is there for the other derivatives, |
|
assuming a suitable storage location can be found. |
|
* EXTLINUX: boot-once support (--once, --clear-once, and |
|
--reset-adv). |
|
* A command is now required to the EXTLINUX installer, i.e. at |
|
least one of --install, --update, --once, --clear-once, or |
|
--reset-adv. |
|
|
|
Changes in 3.55: |
|
* PXELINUX: as per RFC 5071, PXELINUX no longer requires the |
|
use of the magic cookie option (208) for unencapsulated |
|
options. Currently it does not require it for |
|
vendor-encapsulated options (vendor-option-space) either, |
|
but that MAY be reverted in the future if it causes |
|
problems. |
|
* Documentation text files moved to a common "doc" directory; |
|
man pages from the Debian project added to the "man" |
|
directory. |
|
* Correct bug with self-overlapping memory areas when using |
|
the shuffle interface. |
|
|
|
Changes in 3.54: |
|
* Add "menu separator", "menu indent", "menu disabled" |
|
(see README.menu). |
|
* vesamenu: fix handing of VESA modes with noncontiguous |
|
memory buffers. In particular, Qemu/KVM sets up such a mode |
|
when Cirrus Logic emulation is enabled (which is the |
|
default.) |
|
* Support for calling real mode functions using far calls, |
|
with argument on the stack. This was implemented to support |
|
the BIOS BBS specification, but subsequent experiments show |
|
that the at least one of the most common BIOS cores, Award, |
|
passes the presence check but doesn't actually implement the |
|
functionality. |
|
|
|
Changes in 3.53: |
|
* Fix bugs related to the $PnP BIOS functionality on some |
|
platforms. |
|
* PXELINUX: Fix the "naked" version of :: (suppress prefix.) |
|
* elf.c32: better error messages. |
|
* Faster operation under Intel VT virtualization. |
|
* PXELINUX: Fix DHCP bootfile option. |
|
* mkdiskimage: Support more than 1024 cylinders. |
|
* (Hopefully) fix installer on non-x86 platforms. |
|
* Fix shuffle_and_boot_rm, used by linux.c32. |
|
* Fix shuffle_and_boot_pm on 386/486. |
|
* ISOLINUX (at least): fix bss memory overwrite hang. |
|
* MBR: Fix booting from logical partitions. |
|
* Code cleanups. |
|
|
|
Changes in 3.52: |
|
* Handle capitalized F-key commands in the menu system. |
|
* Fix padding error when loading multiple ramdisks. |
|
* Workaround for VMware crashing when trying to print a |
|
message during early kernel boot (does not seem to work, |
|
consider deleting.) |
|
* chain.c32: add the ability to search for a specific MBR |
|
signature at runtime. |
|
* Fall back to the server identity option if the siaddr field |
|
in the DHCP header isn't set. This seems to match the |
|
behaviour of most PXE stacks. |
|
* mkdiskimage: give the generated disk image an MBR signature. |
|
* MEMDISK: Fix failures on some BIOSes. |
|
* Simple menu system: new "MENU HIDDEN" option to not display |
|
the menu unless the user presses a key. |
|
* Simple menu system: support MD5-encrypted passwords (modern |
|
Unix standard style, with "$1$" prefixes.) |
|
* pcitest.c32: now functions as a full "lspci". Thanks to |
|
Erwan Velu for this work. |
|
* MEMDISK: Make EDD actually work. |
|
* ISOLINUX: Fix for certain broken CD-ROM BIOSes which |
|
randomly corrupted register FS. |
|
* Simple menu system: fix memory overwrite bug that caused |
|
some systems to lock up or behave weirdly. |
|
* Fix building on 64-bit systems without a 32-bit libc installed. |
|
|
|
Changes in 3.51: |
|
* EXTLINUX: Fix failure to find the configuration file. |
|
|
|
Changes in 3.50: |
|
* New keywords allow the type of file to be specified in the |
|
configuration file. |
|
* It is now supported to load a different configuration file |
|
with the CONFIG keyword. |
|
* Fix API call 0x0019 (Read Disk.) |
|
* MENU AUTOBOOT, MENU TABMSG, MENU PASSPROMPT allows |
|
internationalization of menu messages. |
|
* A new feature, TEXT HELP, allows the administrator to set |
|
a multi-line help message for individual selections. |
|
* Fix API call 0x0012 (Cleanup, shuffle and boot.) |
|
* New API call "Cleanup, shuffle and boot to flat protected mode" |
|
* New API call "Cleanup, shuffle and boot to real mode", |
|
similar to API call 0x0012 but allows arbitrary register setting. |
|
* Introduce a library interface for loading arbitrary binary |
|
formats with relatively easily understood code. See |
|
the elf.c32 module for an example on how to use it. |
|
* New module "elf.c32", to load a protected-mode ELF kernel. |
|
* MBR (old and new): Fix bug in CHS mode when LBA > |
|
65535*sectors. |
|
* vesamenu: fix decoding of palettized PNG images. |
|
* Update the Linux kernel boot protocol. |
|
* PXELINUX: Press Ctrl-N at the boot prompt to read out the |
|
network info. |
|
* Instead of the (non-existent) MAC, use the client identifier |
|
for networks like Infiniband and Firewire/1394. |
|
* Add a new INCLUDE command to the core syslinux parser. |
|
* Allow binding help text to F11 and F12. |
|
* F-key help now available in the simple menu system. |
|
* Disabled the polling for ARP during idle. It is simply too |
|
slow on some (broken!) PXE stacks. |
|
* PXELINUX: also try to fetch the config file based on UUID. |
|
* SYSLINUX/EXTLINUX: New RAID mode (-r) which calls the BIOS |
|
to load the next device (typically the next drive) on boot |
|
failure. |
|
|
|
Changes in 3.36: |
|
* MEMDISK: Disable EDD by default on floppy disks. EDD can be |
|
enabled with the "edd" option and disabled with "noedd". |
|
This (hopefully) should make Ghost work again. |
|
* SYSLINUX: "unix" installer now uses Linux ioctls instead of |
|
using libfat. |
|
* New MBR which can boot from logical partitions. |
|
* SYSLINUX: Fix bug in detecting special extensions which was |
|
introduced in 3.35 :( |
|
* PXELINUX: Unbreak chainbooting FreeBSD (and possibly others.) |
|
|
|
Changes in 3.35: |
|
* MEMDISK: New "safeint" mode. |
|
* MEMDISK: Be more compliant with the PnP BIOS spec. |
|
* MEMDISK: Turn on EDD support by default. |
|
* MEMDISK: Try to work on some machines on which it would not |
|
work when there was no floppy drive in the system. |
|
* Simple menu system: fix serial console support (broken in |
|
3.30). |
|
* SYSLINUX: Support subdirectories. Like ISOLINUX, the |
|
"current directory" is the directory in which syslinux.cfg |
|
is found; this is searched for in the sequence |
|
/boot/syslinux, /syslinux, /. As a side benefit, label names |
|
like "linux-2.6.18" and "linux-2.6.19" are now supported. |
|
|
|
To install ldlinux.sys in a subdirectory, pass the -d |
|
directory option to the SYSLINUX installer. |
|
|
|
This work was sponsored by slax.org (thanks, Tomas!) |
|
* New API call: read disk. |
|
* Invoke ONERROR on initrd load failure. |
|
|
|
Changes in 3.31: |
|
* The simple menu system (menu.c32 and vesamenu.c32) now |
|
support loading more than one configuration file at a time, |
|
using MENU INCLUDE or by specifying multiple filenames. |
|
* The MENU COLOR statement can now control the shadowing mode. |
|
|
|
Changes in 3.30: |
|
* libcom32 extended to support graphics mode and graphical console. |
|
* vesamenu.c32, new graphical version of the Simple |
|
Menu System, see README.menu. |
|
* New com32 modules by Erwan Velu do selection based on CPUID |
|
or PCI devices present. |
|
* RPM spec: add syslinux-tftpboot module; move syslinux by |
|
default to the /usr/share/syslinux directory. |
|
* RPM spec: extlinux is now a separate package. |
|
|
|
Changes in 3.20: |
|
* EXTLINUX: New options --install (-i) and --update (-U), to |
|
make it clear if a boot loader should be installed or |
|
updated. For now, defaults to --install for compatibility; |
|
a future version will require one of these options. |
|
* New library functions to load and place files in memory. |
|
* mboot.c32 bug fixes. |
|
* Remove 8 MB kernel size restriction. |
|
* Add "klibc" target for building unix/syslinux and |
|
extlinux/extlinux with klcc (klibc-1.4.27 or later.) |
|
* PXELINUX: Fail (and eventually reboot) if no configuration |
|
file was found. |
|
* COM32 module by Erwan Velu to make decisions based on DMI |
|
info. |
|
* Fix issue where going back and forth between menus a lot |
|
would cause a hang. |
|
* ISOLINUX: Fix bug which made "cd boot sectors" not work. |
|
|
|
Changes in 3.11: |
|
* MEMDISK: Fix bug by which accessing the real floppy disk |
|
as B: in MS-DOS was broken. |
|
* Simple menu system: allow tweaking of the screen layout. |
|
* Simple menu system: better command-line editing, correctly |
|
handle command lines above 256 characters. |
|
* PXELINUX: revert memory allocation change that caused |
|
problems on some network cards. |
|
* MEMDISK: Try work around a bug on some BIOSes when no |
|
physical floppy disk is present in the system. |
|
* Enable the 16550A FIFOs, if present, when doing serial |
|
console. |
|
* New "totaltimeout" command establishes a timeout without |
|
regard for any user input. |
|
* Simple menu system: timeout behaviour now more in line with |
|
user expectations. |
|
* Simple menu system: "ontimeout" should now work correctly. |
|
|
|
Changes in 3.10: |
|
* gcc 4.0.1 compilation fixes. |
|
* Add support for querying the PCI BIOS in libcom32 |
|
(used by ethersel et al.) |
|
* Fix PCI handing (ethersel etc) on several old chipsets (and |
|
VMWare.) |
|
* Try to deal with systems with broken EBIOS. |
|
* New API call to do "localboot". |
|
* New API call to query features. |
|
* New API call to run kernel image, a lower-level call than |
|
"run command". See comboot.doc. |
|
* Fix for bug in EBIOS code discovered by Arwin Vosselman. |
|
* NOESCAPE security fix. |
|
* Comments are now recognized even without a space following #. |
|
* Fix incorrect handling of mixes of entries with and without |
|
MENU PASSWD. |
|
* The idle API call now harmlessly returns failure if it is a |
|
no-op. That way the caller can decide whether or not to |
|
bother invoking it again. |
|
* Temporarily disable the idle API call on PXELINUX, due to |
|
some platforms on which the idle API call seems to hang; this |
|
problem has not yet been debugged. |
|
* MEMDISK: the handling of DOSEMU-headered images was broken; |
|
fix it. |
|
* EXTLINUX: symlinks are now supported. |
|
* Simple menu system: N and P now work correctly as hotkeys. |
|
* MEMDISK: more BIOS bug workarounds. |
|
|
|
Changes in 3.09: |
|
* gcc4 compilation fix. |
|
* <BEL> (Ctrl-G) in message files now causes a beep. |
|
* Reduce the command line to 511 characters; 1023 caused |
|
memory overflows. |
|
|
|
Changes in 3.08: |
|
* SYSLINUX: Fix performance regression (-s mode always |
|
enabled.) |
|
* Add API function for idle loop. |
|
* libutil: Add do_idle() function for idle loop, make |
|
get_key() use it. |
|
* libutil: Add SHA-1 and base64 functions. |
|
* Simple menu system: add password support. |
|
* EXTLINUX: Sparse files now handled correctly. |
|
* EXTLINUX: Large directories now handled correctly. |
|
* ALL: At the prompt, Ctrl-X now forces text mode. |
|
* Fix configuration file parsing error, that could cause |
|
hangs. |
|
* Rewritten advanced menuing system from Murali Ganapathy. |
|
* MEMDISK: New "bigraw" mode to work around certain broken |
|
BIOS flash programs. |
|
* COM32 module to boot Multiboot systems, including Xen. See |
|
com32/modules/mboot.doc. |
|
* Max command line changed to 1023 characters. Note that the |
|
kernel proper still can only handle 255 characters without |
|
patching, and COM16 binaries can only handle 125 characters. |
|
|
|
Changes in 3.07: |
|
* Fix chainloading (chain.c32). |
|
* Fix zlib build problem. |
|
* Use a private copy of <linux/ext2_fs.h>. |
|
|
|
Changes in 3.06: |
|
* Fix typo that caused the ramdisk to load in the wrong place. |
|
|
|
Changes in 3.05: |
|
* New API function "shuffle and boot"; allows COM32 modules to |
|
load or construct (almost) arbitrarily complex objects, |
|
e.g. a kernel and its initrd/initramfs in pieces, and have |
|
the API core reorganize memory for booting. (A library API |
|
for this function will be introduced in a later version.) |
|
* The initrd= option now supports multiple filenames separated |
|
by commas. This is mostly useful for initramfs, which can |
|
be composed of multiple separate cpio or cpio.gz archives. |
|
(Note: all files except the last one are zero-padded to a 4K |
|
page boundary. This should not affect initramfs.) |
|
* EXTLINUX: Fix API function 000Ah (get derivative-specific |
|
info). |
|
* libcom32/ethersel: Support PCI Config Mechanism #2 on |
|
machines still infested with that hideous old hack. |
|
* SYSLINUX: Fix directory-parsing bug. |
|
|
|
Changes in 3.02: |
|
* SYSLINUX: The "unix" installer now sets the MS-DOS |
|
attributes (hidden, system, readonly.) |
|
* COM32 library: build the .lnx (test modules for running |
|
under Linux) as architecture native modules, in case |
|
i386 devel libraries aren't installed. |
|
* EXTLINUX: Hack for systems which don't have BLKGETSIZE64 |
|
defined in the standard header files. |
|
* Simple menu system: minor aestetic improvements, and try to |
|
work better over a serial console (speed, and readability on |
|
monochrome terminal emulators.) |
|
* New CONSOLE directive to control output on the video console |
|
(useful for dealing with some broken serial-forwarding |
|
BIOSes.) |
|
* New com32 module "ethersel" for searching for an Ethernet |
|
card and selecting the proper version of Etherboot. |
|
* EXTLINUX: Allow the user to override the detected geometry. |
|
Add help. |
|
|
|
Changes in 3.01: |
|
* EXTLINUX, SYSLINUX: Fix compile errors on some systems. |
|
* EXTLINUX: Default to zipdrive geometry (64 heads, 32 |
|
sectors) if no other geometry can be detected. |
|
|
|
Changes in 3.00: |
|
* SYSLINUX: Support FAT32 and EDD. As an unfortunate |
|
consequence, LDLINUX.SYS is no longer an ordinary file; it |
|
is block-mapped at install time, which means it can only be |
|
written using the syslinux installers. |
|
* SYSLINUX: Reorganize the source code for the installers; |
|
each one of the installers (dos, win32, unix, mtools) is now |
|
built in its own subdirectory. In particular, "mtools" is |
|
the unprivileged installer which uses mtools; "unix" is the |
|
privileged installer which uses system calls. |
|
* SYSLINUX: Completely rewritten DOS installer in C. |
|
* ALL: "label" statement information is now stored in a |
|
compressed format, which means that a lot more labels are |
|
permitted (500-1000 in a typical configuration, but depends |
|
on the complexity.) |
|
* EXTLINUX: New derivative, which boots from an ext2/ext3 |
|
filesystem. |
|
* SYSLINUX: The DOS and Win32 installers can now optionally |
|
write the boot sector to a file instead of the real boot |
|
sector. This is not supported in the Linux installers, |
|
however. |
|
* ALL: New NOESCAPE command, disables the "hold down the Shift |
|
key to display the prompt" behaviour. |
|
* New simple menu system, as an alternative to the advanced |
|
menu system already present. See README.menu for details. |
|
* PXELINUX: Filenames can now be prefixed with an IP address |
|
or DNS name plus :: (e.g. 192.0.2.1::filename or |
|
server.domain.com::filename), which downloads a file from an |
|
alternate TFTP server, or just a :: (e.g. ::filename), which |
|
suppresses the common pathname prefix. See pxelinux.doc. |
|
* SYSLINUX: Add an -m option to the DOS and Win32 installers |
|
to write an MBR and -a to mark the partition SYSLINUX is |
|
being installed on active. |
|
* MEMDISK: Give a way to query the boot loader type while |
|
running MEMDISK; see memdisk/memdisk.doc and |
|
sample/mdiskchk.c. |
|
* mkdiskimage: substantially improved mkdiskimage which, among |
|
other things, can now be used to initialize USB keys as |
|
zipdrives; see README.usbkey for more information. |
|
|
|
Changes in 2.13: |
|
* MEMDISK: Fix command-line parsing "brown paper bag" class |
|
bug. |
|
* MEMDISK: Add "raw" mode to support the DOS boot disk from |
|
WinME/XP, which seems to deliberately crash the system |
|
when someone uses the "INT 15h mover" highmem API. |
|
* Make "make install" do something sane for the com32 |
|
development environment. |
|
* In the spec file, create a separate -devel RPM for the com32 |
|
development environment. |
|
|
|
Changes in 2.12: |
|
* Simple C library, based on klibc, for writing COM32 |
|
programs. |
|
* Fix the handling of file length in loading of COM32 |
|
programs. |
|
* MEMDISK: Work around a linker bug by rearranging the code to |
|
not use the linker for the 16-bit code. |
|
* SYSLINUX: If we're building on a machine without a Win32 |
|
(mingw) compiler, just skip building syslinux.exe. |
|
* ISOLINUX: Support non-mkisofs mastering programs, at least |
|
as long as the image is single-session. For best results, |
|
ISOLINUX should be the only boot loader installed. |
|
* MEMDISK: Allow the user to specify that the simulated disk |
|
should be write-protected. |
|
|
|
Changes in 2.11: |
|
* ALL: Add an API call to get the configuration file name. |
|
* SYSLINUX: Fix bug in 2.10 that prevented it from working |
|
correctly for a lot of people. |
|
* SYSLINUX: In the installer, make mtools a bit less fussy. |
|
* Make the menu system compile with newer gcc's. |
|
|
|
Changes in 2.10: |
|
* MEMDISK: Handle images compressed with zip as well as with |
|
gzip. Some Windows-based image tools apparently generate |
|
these kinds of images by default. Patch by Patrick |
|
LoPresti. |
|
* Major menu improvement from Murali Ganapathy. |
|
* ISOLINUX: Wonderfully sick and brilliant workaround for |
|
severe bugs in certain Award BIOSes; from Knut Petersen. |
|
* SYSLINUX: Fix for the nomtools installed, from Frederic |
|
Pasteleurs. |
|
* PXELINUX: Fix handling of IP numbers in the ranges |
|
100-109 and 200-209. |
|
* ALL: New option "allowoptions" (defaults to 1), which |
|
controls if options are allowed on the command line or not. |
|
* SYSLINUX: Support building under klibc (see the klibc |
|
distribution for details.) |
|
|
|
Changes in 2.09: |
|
* SYSLINUX: Remove residual setuid crap from |
|
syslinux-nomtools. |
|
* Handle video pages correctly when using the API functions. |
|
* Handle compiling on an x86-64 platform correctly. |
|
* Menu system from Murali Krishnan Ganapathy; see the menu |
|
directory for information. |
|
* COMBOOT: Allow COMBOOT programs to change screen text mode. |
|
* COMBOOT: Correct the documentation of how to detect |
|
SYSLINUX from COMBOOT!!!! |
|
* COMBOOT: Fix "get key without echo" API function. |
|
* SYSLINUX: Fix bug that affected the API open function. |
|
* ALL: Improve the E820 memory parser, to work around some |
|
buggy BIOSes. |
|
|
|
Changes in 2.08: |
|
* Add new configuration command "ontimeout" to allow timeout |
|
to have a different action than just pressing Enter. |
|
* Add new configuration command "onerror" to allow a custom |
|
command to be executed in case the kernel image is not found. |
|
* Fix bugs in the COMBOOT/COM32 command-line parsing. APPEND |
|
now works with COMBOOT/COM32 images. |
|
* PXELINUX: Poll for ARP requests while sitting at the |
|
prompt. This makes some boot servers a lot less unhappy. |
|
* PXELINUX: Actually free sockets when we get a failure |
|
(including file not found.) This bug would cause us to run |
|
out of sockets and thus "go deaf" after a while. |
|
* MEMDISK: Add an API to query for the existence of MEMDISK. |
|
* SYSLINUX: Fix loading boot sectors (.bs/.bss) from floppy |
|
disk. |
|
* .c32 is now one of the extensions searched for |
|
automatically. |
|
* PXELINUX: RFBG.exe seems to randomly overwrite memory |
|
location 0x5700. Thus, don't use it! |
|
* PXELINUX: Change pathname length max from 63 to 127; change |
|
max vkernels from 128 to 64. |
|
* Support Ctrl-U -> kill entire command line input. |
|
* The "samples" directory contains a (barely at all tested) |
|
chain loading example, chain.c32, which may be used to |
|
chainload local floppy disks and hard disks. Use with |
|
"chain fdN" or "chain hdN [partition]"; N = 0 for the first |
|
drive of each type. |
|
|
|
Changes in 2.07: |
|
* MEMDISK: Workaround for BIOSes which go into a snit when |
|
they get a RESET command for the floppy system when there is |
|
no floppy in the system. |
|
* PXELINUX: Add "ipappend 2", which passes the hardware |
|
address of the boot interface to the kernel as a |
|
command-line option. |
|
* mkdiskimage: fix the generation of the end limit. |
|
* PXELINUX: Fix multiple bugs in chainloading of other NBPs. |
|
* MEMDISK: Fix bug that would occationally cause "ran out of |
|
input data" when using compressed disk images. |
|
* SYSLINUX: Updates for the win32 installer (from Lars Munch.) |
|
* PXELINUX: PXELINUX-specific options are now recognized both |
|
in a vendor-option-space (a.k.a. type 43 encapsulated) as |
|
well as in a site-option-space (unencapsulated.) |
|
* COM32: Don't crash when DS != 0. |
|
* COMBOOT/COM32: Make file reading work correctly. Thanks to |
|
Phung Chi Kien for submitting a test program. |
|
|
|
Changes in 2.06: |
|
* ALL: Fix problem that would occationally cause a |
|
boot failure, depending on the length of the kernel. |
|
* ISOLINUX: Fix problem that would occationally cause a |
|
boot failure, depending on the length of directories. |
|
* SYSLINUX: Win32 installer now flushes buffers. |
|
* ppmtolss16: Be fully compliant with the PNM spec; |
|
actually process comments in the header and odd |
|
alignments of the various parameters, as well as |
|
"plain" (not raw) files and PBM and PGM files. |
|
* PXELINUX: Lower the default MTU to 1472 in order to deal |
|
with systems with slightly nonstandard MTUs, and PXE |
|
stacks which don't defragment correctly. Unfortunately this |
|
is very hard to test dynamically. |
|
|
|
Changes in 2.05: |
|
* PXELINUX: Add a default query based on the hardware address |
|
of the boot device. This is in lower case hexadecimal form |
|
separated by dashes and including the hardware type, for |
|
example, the Ethernet (type 1) address 88:99:AA:BB:CC:DD |
|
would query the file pxelinux.cfg/01-88-99-aa-bb-cc-dd. |
|
* PXELINUX: Fix bug involving non-IP-based config file names. |
|
* SYSLINUX: New installer for WinNT-based systems, from Lars |
|
Munch. |
|
* MEMDISK: Fix handling of memory region overlap when |
|
decompressing. Thanks to Mikhail Kupchik for identifying |
|
the problem. |
|
|
|
Changes in 2.04: |
|
* ALL: Reclaim even more low memory by observing that |
|
comboot_seg == real_mode_seg is perfectly fine, and by the |
|
fact that the 1000h segment managed to get unused in all |
|
derivatives... |
|
* PXELINUX: Attempt to negotiate full Ethernet-sized blocks |
|
(1468 bytes) using the blksize option. |
|
* SYSLINUX: Resurrect the old no-mtools version of the |
|
installer, although as a root-only tool. Some distributors |
|
have indicated that they need a small standalone installer. |
|
* MEMDISK: Fix a memory offset computation error when |
|
installing compressed disks which generally would cause |
|
1 MB of memory to be wasted. |
|
* MEMDISK: Fix installing the E820 memory map. Calling |
|
INT 15h AX=0E820h with MEMDISK 2.03 loaded would give a |
|
completely corrupt memory map. |
|
* SYSLINUX: Make libsyslinux a dynamic library, so that it can |
|
be updated separately from client programs. The whole idea, |
|
after all, is to enable alternate programs to become |
|
syslinux installers. |
|
* Include an rpm spec file in the distribution, so rpmbuild |
|
-ta works. |
|
|
|
Changes in 2.03: |
|
* Actually support comment lines in the configuration file. |
|
* PXELINUX: Try to resolve some problems with stack switches. |
|
* PXELINUX: Handle PXE stacks with broken routing. |
|
With these workarounds, the remote install PXE boot floppy |
|
(rbfg.exe) from Argon Technologies should work correctly. |
|
* Fix problems with Perl scripts in UTF-8 locales. |
|
* You probably need NASM 0.98.34 or later to compile this |
|
version. 0.98.36 is recommended. |
|
* MEMDISK: Now supports gzip compressed images. |
|
|
|
Changes in 2.02: |
|
* SYSLINUX: Security flaws have been found in the SYSLINUX |
|
installer when running setuid root. Rewrite the SYSLINUX |
|
installer so it uses mtools instead. It therefore now |
|
requires mtools (specifically mcopy and mattrib) to exist on |
|
your system, but it will not require root privileges and |
|
SHOULD NOT be setuid. |
|
|
|
Changes in 2.01: |
|
* MEMDISK: Fix memory sizing bug when the ramdisk crosses the |
|
16 MB boundary. |
|
* MEMDISK: Add a "pause" option to stop immediately before |
|
booting, to read off the messages. |
|
* MEMDISK: Support disk images with DOSEMU headers. |
|
* Update the mkdiskimage script to handle newer mtools |
|
versions, and be able to generate disk images with DOSEMU |
|
headers (controlled by the -d option). |
|
* Fix the COM32 sample program. |
|
* PXELINUX, ISOLINUX: Fix some COMBOOT API calls. |
|
* PXELINUX: Doc fix. |
|
* Build SYSLINUX into a small library for encapsulation into |
|
other programs (however, please keep in mind this is a GPL'd |
|
library.) |
|
* SYSLINUX: Make installer work with "owner" in /etc/fstab. |
|
* SYSLINUX: Fix issue with working on nonpartitioned hard disk |
|
devices. THIS CONFIGURATION IS NOT RECOMMENDED. |
|
|
|
Changes in 2.00: |
|
* ALL: Add support for "COM32" (32-bit COMBOOT) images. |
|
* ALL: Add an API for COMBOOT/COM32 images. See comboot.doc |
|
for details. There is a C development environment for |
|
COM32 being created; it should be ready at some point in |
|
the future. |
|
* Fix mbr.asm so that it actually works. |
|
* SYSLINUX: The syslinux installer *SHOULD* now be safe to |
|
run setuid root. |
|
* PXELINUX: Fix bug where PXELINUX would override random |
|
chunks of the UNDI code segment! Thanks to Kevin Tran for |
|
finding this bug. |
|
* ISOLINUX: Fix a bug related to slashes in pathnames. |
|
* ISOLINUX: Fix a bug in handling initrds over 128 MB. |
|
* ALL: Make the <Ctrl-V> key print out the version; this is |
|
to help debugging. |
|
* Add a small script, mkdiskimage, to create a DOS-formatted |
|
hard disk image using mtools. This may be useful in |
|
conjunction with MEMDISK. |
|
* ISOLINUX: Search for a /boot/isolinux directory as well as |
|
/isolinux. |
|
* ALL: Fix a bug related to very long configuration files. |
|
* PXELINUX: Work around a NASM bug which would result in no |
|
delay before reset if an error occurs. |
|
|
|
Changes in 1.76: |
|
* ISOLINUX: Remove code no longer used which caused hangs on |
|
some Toshiba laptops. |
|
|
|
Changes in 1.75: |
|
* ALL: NASM 0.98.32 or later is now required to build |
|
SYSLINUX from sources. |
|
* SYSLINUX: put back in the workaround for the BIOS floppy |
|
table. This seems to be a requirement for "extended" floppy |
|
formats to work correctly. |
|
* SYSLINUX: No longer warn if one is trying to boot on a 286 |
|
or older. The above BIOS workaround no longer fits if the |
|
requirement to use only 8086-compatible code in the early |
|
boot is maintained. It made sense in 1994, but in 2002 a |
|
286 or older is a museum object. |
|
* SYSLINUX: Use a downright bizarre, stateful algorithm to try |
|
to guess the maximum transfer size. I am *hoping* this will |
|
cut down on the number of systems for which -s is required |
|
to work at any acceptable speed. |
|
* ISOLINUX: Add a few more workarounds for various broken El |
|
Torito BIOSes. |
|
* Make sure .depend files aren't accidentally packed... |
|
* ALL: Fix bugs in the extension-detect code; this caused |
|
files like COMBOOT images and CD boot sectors to be |
|
mis-identified as Linux kernels and rejected. |
|
* ALL: Fix the return from COMBOOT. |
|
* ALL: Do some of the early groundwork for supporting DOS |
|
system calls in COMBOOT. |
|
* Get rid of unnecessary "near" directives, making the code |
|
bigger. |
|
* PXELINUX: Put the PXE stack back in the init state before |
|
invoking a chain-loaded NBP. |
|
* PXELINUX: Actually found the combination of calls that |
|
allows some (most?) PXE 2+ stacks to be unloaded from memory |
|
properly. |
|
* PXELINUX: Add "keeppxe" command-line option to disable |
|
the standard unloading of the PXE stack. |
|
|
|
Changes in 1.74: |
|
* SYSLINUX: fix bug that would cause valid kernel images to be |
|
labelled "invalid". |
|
|
|
Changes in 1.73: |
|
* Work on removing gratuitous differences between modules. |
|
* Break up the source in common and module-specific files. |
|
* PXELINUX: Allow chaining of other PXE NBPs. |
|
* ISOLINUX: Allow loading "CD-ROM boot sectors". |
|
* ALL: generalize the definition of a boot sector/NBP. |
|
|
|
Changes in 1.72: |
|
* PXELINUX, ISOLINUX: Fix bugs in the new core code. |
|
|
|
Changes in 1.71: |
|
* Fix a "brown paper bag" class bug in the new core code. |
|
|
|
Changes in 1.70: |
|
* Major code restructuring. |
|
* Relax the conventional memory limits somewhat. |
|
* MEMDISK: Set up the "version number string" pointer in the |
|
header correctly. |
|
* SYSLINUX: Fix, again, "the bug that won't die": the use of |
|
the offset parameter with the SYSLINUX installer. |
|
* SYSLINUX: Fix possible superblock corruption problem in the |
|
SYSLINUX installer. |
|
|
|
Changes in 1.67: |
|
* Handle bug in the location of initrd. |
|
|
|
Changes in 1.66: |
|
* MEMDISK: Make compile with newer versions of gcc. |
|
|
|
Changes in 1.65: |
|
* ISOLINUX: Support booting disk image files (to boot DOS or |
|
other non-Linux operating systems), *IF* the BIOS works |
|
correctly; unfortunately many BIOSes apparently don't. |
|
* Support Linux boot protocol version 2.03 (explicitly |
|
specify the initrd address limit.) |
|
* Handle small "pseudo-kernels"; images that use the Linux |
|
kernel boot protocols but are less than 64K in size. |
|
* MEMDISK: New subsystem; this is a driver which allows |
|
legacy OSes to boot using an in-memory simulated disk. |
|
See memdisk/memdisk.doc for more info. |
|
* PXELINUX, ISOLINUX: Correctly handle files larger than 65535 |
|
blocks (32 MB for PXELINUX, 128 MB for ISOLINUX.) |
|
* PXELINUX: Make a best-effort attempt at freeing all memory |
|
claimed. From the looks of it, it will fail on most PXE |
|
stacks. |
|
|
|
Changes in 1.64: |
|
* Limited support for hardware flow control when using a |
|
serial port console. |
|
* Support specifying the serial port I/O address explicitly. |
|
* Make DOS installer hopefully behave more nicely when used on |
|
recent Windows versions. |
|
* Fix returning to text mode when a font has been specified. |
|
* Attempt to detect missing serial port hardware and disable |
|
the serial port if there is nothing there. |
|
|
|
Changes in 1.63: |
|
* Make the ppmtolss16 program handle color conversion more |
|
correctly. |
|
* Clean up "make install" target, honour INSTALLROOT if it |
|
exists. |
|
* SYSLINUX: Fix stack-smash bug identified by Steffen |
|
Winterfeldt. |
|
* Hopefully fix return-to-text-mode on some graphics cards. |
|
* ISOLINUX: Bug workaround for Award BIOS 4.51, and perhaps |
|
other buggy BIOSes as well. |
|
|
|
Changes in 1.62: |
|
* PXELINUX: Allow the DHCP server to override the |
|
configuration file name and pathname prefix, using |
|
"site-specific" DHCP options. |
|
* PXELINUX: Documentation fixes. |
|
* PXELINUX: Fix the "ipappend" option; the last two values |
|
were reversed vs. what the kernel expected. |
|
* Introduce a way to return to text mode once we are already |
|
in graphics mode. This may be useful for F-key help |
|
screens. |
|
* Fix several bugs in the way return to text mode was handled. |
|
|
|
Changes in 1.61: |
|
* ISOLINUX: Support full pathname searches. Max length for a |
|
pathname is 255 characters. As a result, only 64 "label" |
|
statements are supported in ISOLINUX. |
|
* PXELINUX: Max filename length extended to 63 characters. |
|
|
|
Changes in 1.60: |
|
* Add support for graphical splash screens. |
|
* Add mode control characters, which allows you to control |
|
message display output depending on output mode (text, |
|
graphics, or serial port.) |
|
* ISOLINUX: New program, which boots Linux from a CD-ROM |
|
without using floppy emulation mode. See isolinux.doc for |
|
more details. |
|
* PXELINUX: Don't search for boot sector file types, since |
|
they don't work anyway. |
|
* SYSLINUX: Document the LOCK command for Win9x, and the error |
|
dialog box for WinNT/2K. |
|
|
|
Changes in 1.54: |
|
* PXELINUX: Fix code for finding !PXE from PXENV+. This was |
|
due to a spec bug; match the most recent spec since that |
|
seems to be what implementations actually do. |
|
* SYSLINUX: Add some smarts to the boot sector, which |
|
hopefully should reduce the number of systems which require |
|
stupid mode ("syslinux -s"). |
|
* PXELINUX: Document further some of the pathologies with old |
|
PXE stacks. |
|
* When specifying a "default" command line, no longer |
|
automatically appent "auto". See the "DEFAULT" command in |
|
syslinux.doc for more information. |
|
* PXELINUX: Clean up the allocation of local socket numbers. |
|
|
|
Changes in 1.53: |
|
* PXELINUX: Rename pxelinux.bin to pxelinux.0, to match what |
|
most PXE servers seem to expect. |
|
* PXELINUX: Update the DHCP/boot server setup documentation. |
|
* PXELINUX: Support new "localboot" option for "label" |
|
sections. |
|
* PXELINUX: More robust parsing of DHCP/boot server packets. |
|
* PXELINUX: Include a small utility program "gethostip" to |
|
compute hexadecimal IP addresses. |
|
|
|
Changes in 1.52: |
|
* PXELINUX: Fix bugs introduced by new A20 code. (SYSLINUX |
|
has also been changed for code consistency reasons, but I'm |
|
pretty sure the changes are don't care on SYSLINUX.) |
|
* Documentation updates. |
|
* PXELINUX: Add "ipappend" option to generate an ip= option to |
|
the kernel. |
|
|
|
Changes in 1.51: |
|
* PXELINUX: Not all PXE stacks fill in the IP address for a |
|
type 3 cached info query. Use a type 2 cached info query |
|
for this information (only.) |
|
* Yet another attempt at A20 coding. Now support BIOS call |
|
15:2401 as well, and handle machines which always have A20 |
|
on separately. |
|
* Support memory detection using INT 15h, AX=0E820h. BIOS |
|
manufacturers have apparently gotten sloppy about keeping |
|
INT 15h, AX=0E801h working properly. |
|
* Don't issue <CR><LF> onto the serial port when we're doing |
|
screen wraparound. |
|
|
|
Changes in 1.50: |
|
* Yet another A20-code update. It seems some "legacy-free" |
|
machines and embedded gear simply don't have a KBC to talk |
|
to, and that waiting for one will wait forever. Sigh. |
|
|
|
Changes in 1.49: |
|
* SYSLINUX: Implement a hack for BIOS drivers which hog significant |
|
chunks of low memory during boot. (Note: PXELINUX already |
|
had this modification. SYSLINUX does still require that the |
|
low 512K is available; PXELINUX requires 384K. Machines |
|
with a physical memory hole in the low 640K cannot boot |
|
Linux no matter what.) Depending what the reason is for the |
|
memory hole, a new kernel (2.4.0-test3-pre3 or later) may be |
|
required. |
|
* SYSLINUX: Default installer binary now compiled against |
|
glibc 2.1. If this is inappropriate for your system and you |
|
still want to use the offical version of SYSLINUX, please |
|
follow the instructions in "distrib.doc" to rebuild the |
|
installer. |
|
* SYSLINUX: Linux installer program now supports -o <offset> |
|
option which does a loopback mount with the |
|
-o loop,offset=<> option. Useful to run SYSLINUX on an |
|
individual partition of a whole-harddisk image. |
|
* Include the source code to a Master Boot Record (MBR) |
|
functionally equivalent to the one installed DOS except it |
|
includes EBIOS support, and should be resistant to geometry |
|
changes. The MBR code is public domain. |
|
* PXELINUX: Fix "double p" bug: if the tftp prefix was null, |
|
all filenames would get a "p" preprended, e.g. |
|
"ppxelinux.cfg" and "pvmlinux". |
|
|
|
Changes in 1.48: |
|
* PXELINUX: Workaround for PXE ROMs based on the Intel PXE PDK |
|
3.0 build 071 and earlier: missing !PXE structure pointer. |
|
* PXELINUX: Handle larger BOOTP/DHCP packages. |
|
* PXELINUX: The command line passing was broken; fix. |
|
* PXELINUX: Make COMBOOT images work. |
|
* PXELINUX: Documentation on how to make booting work using |
|
the PDK 3.0-derived clients, which aren't so generous as to |
|
allow booting with only "PXEClient" specified. |
|
|
|
Changes in 1.47: |
|
* PXELINUX: RFC 1123 states that a TFTP implementation MUST |
|
use adaptive timeout, "at least an exponential backoff of |
|
retransmission timeout is necessary." Implement a very |
|
simple exponential backoff for retransmits. |
|
* PXELINUX: Updated documentation, including pointer to new |
|
TFTP server. |
|
* PXELINUX: When sending ERROR due to bad OACK, use the proper |
|
destination port number (why are TFTP port numbers so odd?) |
|
* PXELINUX: If the boot dies in the middle somewhere, |
|
eventually give up and reset the machine (unattended |
|
operation.) |
|
|
|
Changes in 1.46: |
|
* New program PXELINUX to do network booting using a |
|
PXE-compliant (Pre-Execution Environment) network booting |
|
PROM. See pxelinux.doc for details. |
|
|
|
Changes in 1.45: |
|
* Serial console support. See syslinux.doc for details. |
|
|
|
Changes in 1.44: |
|
* Change HIGHMEM_MAX to 38000000h to (hopefully) avoid the |
|
kernel stepping on it; 3f000000h was apparently a higher |
|
limit than the kernel used! |
|
|
|
Changes in 1.43: |
|
* Add sys2ansi.pl script to display the contents of a |
|
colorized SYSLINUX file. |
|
* Changed the io_delay once again, after a report that the |
|
old delay port causes hangs on some systems. |
|
|
|
Changes in 1.42: |
|
* Frob the "fast A20 gate" port as well as the keyboard |
|
controller; will this help systems with problems? |
|
* Be even more paranoid about A20, unfortunately even this |
|
seems to be not paranoid enough... what I don't understand |
|
is that if there is hardware out there *this broken*, how |
|
can it run Linux at all? Report an error message rather |
|
than hang forever if A20 is stuck. |
|
* Include some intermediate files in the distribution, plus |
|
provide a "make installer" target for distributors to relink |
|
the install programs only. I would prefer the syslinux boot |
|
loader proper to be "binary clean" for debuggablity -- use |
|
"make clean ; make installer" to rebuild the installers only. |
|
|
|
Changes in 1.41: |
|
* Don't get confused by directories, volume labels, or VFAT |
|
long names. |
|
* Use INT 15h, AX=0E801h to query memory size before trying |
|
INT 15h, AH=88h. This not only provides more headroom |
|
between the kernel and the initrd on large-memory machines, |
|
but it appears some recent BIOSes actually have started |
|
returning garbage for the AH=88h (older) call. |
|
* Trust high memory beyond the 15 MB mark if the user has |
|
specified it, or if obtained with INT 15h, AH=0E801h (with |
|
no memory holes above 1 MB.) |
|
|
|
Changes in 1.40: |
|
* Increase A20M delay and put in a test to avoid problems on |
|
certain IBM Thinkpads (thanks to Donnie Barnes of RedHat |
|
for vital info on this one.) |
|
* Support COMBOOT style boot command images. |
|
* Support chain loading (foreign operating systems, e.g. DOS). |
|
* Include a new "copybs" DOS utility to copy a boot sector to |
|
a file (under Linux, use "dd".) |
|
* Fix the DOS installer to work for disks over 32 MB. |
|
* SYSLINUX should now handle disks with more than 65536 tracks. |
|
|
|
Changes in 1.37: |
|
* Fix a bug that caused "label" statements in syslinux.cfg to |
|
not be handled properly. |
|
* Updated the documentation. Among other things, we now allow |
|
up to 128 "label" statements. |
|
|
|
Changes in 1.36: |
|
* Fix for booting old (pre-initrd) kernels. |
|
* It seems at least some versions of OS/2 doesn't set up all |
|
the fields in the superblock correctly. Account for that. |
|
* Fix bug that caused boot failure when using the mem= option. |
|
|
|
Changes in 1.35: |
|
* Loading from partitions now should work properly. (Actually |
|
tested, this time. You should even be able to dd a floppy |
|
to a partition and boot from it.) |
|
* Removed large workaround code for an alleged ancient BIOS |
|
bug I have never actually seen. The -s option should work |
|
on those machines, anyway. |
|
* Support for simple keyboard remappings, same as used by |
|
LILO (once again to support localization.) The program |
|
keytab-lilo.pl from the LILO distribution included to |
|
generate such maps. |
|
* Added a "safe, slow and stupid" (-s) option to the |
|
installers. This option will lobotomize the boot sector to |
|
hopefully work on even very buggy BIOSes. |
|
|
|
Changes in 1.34: |
|
* Ability to load a VGA font on bootup (for localized Linux |
|
distributions.) |
|
|
|
Changes in 1.33: |
|
* Bug fix in the Linux installer. |
|
* Added a workaround for a bug in certain AMI/Intel BIOSes |
|
when booting from CD-ROM. |
|
* Documentation changes. |
|
|
|
Changes in 1.32: |
|
* FAT16 filesystems are now supported. |
|
|
|
Changes in 1.31: |
|
* Now compiles under Linux, using NASM, rather than using |
|
Turbo Assembler under DOS. See http://www.cryogen.com/Nasm |
|
for information about NASM. |
|
* Linux-hosted SYSLINUX installer, as well as a |
|
rewritten DOS installer (now is written in assembler, so we |
|
don't need Turbo C.) |
|
|
|
Changes in 1.30: |
|
* Added support for loading bzImage and initrd loading, and made |
|
SYSLINUX new-setup-code aware (SYSLINUX 1.30 id=0x31). |
|
* Added LILO-style kernel labels; see the LABEL and IMPLICIT |
|
keywords in README file. |
|
* Added support for colorization of intro and help screens. |
|
* The vga= option is now handled correctly. |
|
* Massive rewrite of large chunks of the code in order to |
|
support the first two new features. |
|
|
|
Changes in 1.20: |
|
* Added simple online help at the "boot:" prompt. |
|
* Removed 2880K image as I no longer have access to such a |
|
floppy drive. (Donations accepted!!) |
|
* Decided to distribute the source in a subdirectory rather |
|
than in a nested zipfile. |
|
|
|
Changes in 1.11: |
|
* Removed a sanity check which would cause booting to fail on |
|
Phoenix BIOS version 4.03. Apparently this BIOS is buggy. |
|
|
|
Changes in 1.10: |
|
* Added configuration file SYSLINUX.CFG. This file contains all |
|
configurable options, and can be edited from any OS which can |
|
access an MS-DOS filesystem; there is no longer a need to run |
|
SYSLINUX.EXE except to write the boot sector. |
|
* Default command line now given by "default" line in config |
|
file. |
|
* LINUXMSG.TXT and BOOTMSG.TXT hard-coded file names replaced by |
|
"display" and "prompt" lines in config file. |
|
* LILO-style option appending now supported ("append" line in |
|
config file). |
|
* Prompt timeout is now supported ("timeout" line in config |
|
file). The timeout is cancelled when anything is typed on the |
|
command line. |
|
* Pressing <ESC> or <Ctrl-C> at the Loading... stage now aborts |
|
the kernel loading in progress and returns the user to the |
|
boot: prompt. |
|
* The installer now automatically sets the READONLY flag on |
|
LDLINUX.SYS. |
|
* Added 2880K disk image. |
|
|
|
Changes in 1.03: |
|
* Fixed bug that would prevent booting from double-density |
|
floppies and other DOS filesystems with multiple sectors per |
|
cluster. |
|
* Added 720K disk image. |
|
* Changed default kernel name on disk images to LINUX. |
|
|
|
Changes in 1.02: |
|
* Fixed bug that would garble the command line on recent kernels |
|
with more than 4 sectors of setup code (this wasn't really a |
|
*bug*; rather, a kernel change broke the code. Unfortunately |
|
the Linux boot interface is still sorely undocumented). |
|
* Added BOOTMSG.TXT file support (message file which does not |
|
force display of the boot prompt). |
|
|
|
Changes in 1.01: |
|
* Fixed bug on some (most?) 386 BIOSes would require two boot |
|
attempts.
