4
5		Changes in 3.86:
6		* chain.c32: fix chainloading the MBR of a hard disk (broken
7		in 3.85).
8		* mboot.c32: report the boot loader name in the information
9		structure.
10		* com32: set argv[0] in a com32 module.
11		* core: add a workaround for a bug in Xen HVM older than
12		version 3.3: disable halt on those platforms.
13		* Fix problems where certain operations in com32 modules would
14		cause the core to believe the system was idle.
15		* MEMDISK: fix MBR detection when used with a DOSEMU header or
16		an offset.
17		* MEMDISK: generate the mBFT checksum correctly.
18
19		Changes in 3.85:
20		* gPXELINUX: updated to gPXE 1.0.0.  gPXELINUX can now do NBP
21		chainloading, and does not require a second DHCP.
22		* vesamenu.c32: unbreak the default "grey hole" background.
23		* We no longer have a built-in default of "linux auto".
24		Instead, if no DEFAULT or UI statement is found, or the
25		configuration file is missing entirely, we drop to the boot:
26		prompt with an error message (if NOESCAPE is set, we stop
27		with a "boot failed" message; this is also the case for
28		PXELINUX if the configuration file is not found.)
29		* chain.c32: support chainloading Grub4DOS; patch by Gert
30		Hulselmans.
31		* New tool: sysdump.c32, can be used to produce system
32		information for debugging via tftp or ymodem (serial port).
33		* "vga=current" on the Linux command line is now supported.
34		* chain.c32: support for Windows Recovery Console, via the
35		"cmldr=" option.
36		* chain.c32: should now support loading NTLDR from different
37		type media than loaded from.
38		* chain.c32: support chainloading to a FAT/NTFS partition with
39		invalid "hidden sectors" via the "sethidden" option.
40		* memdisk: fix the mBFT ACPI table.
41		* vesamenu.c32: if the image is smaller than the screen, tile
42		it across the whole screen.
43		* mkdiskimage: -s option for producing a sparse image.
44		* vesamenu.c32: support arbitrary resolution setting (beyond
45		BIOS support) on some Intel-based video chipsets.  This code
46		is a modified version of the "915resolution" tool by
47		Steve Tomljenovic; your mileage might vary.
48
49		Changes in 3.84:
50		* SYSLINUX: make the DOS installer work for MS-DOS 7.x/8.x
51		(Win9x/ME) again.
52		* HDT: updated to version 0.3.6 (numerous changes.)
53		* mboot.c32: now supports video mode setting if requested by
54		the image.
55		* MEMDISK: Fix floppy images of PC-DOS.
56		* MEMDISK: Add support for emulation of CD-ROM images; patch
57		by Shao Miller.
58		* MEMDISK: Comply with the Win9x "safe hook" standard,
59		allowing a protected-mode driver.
60		* MEMDISK: New "mBFT" ACPI table, by analogy with the iSCSI
61		iBFT table.  This allows detection from a protected-mode
62		operating system without EDD support.
63		* 32-bit version of the gfxboot loader (gfxboot.c32), so far
64		experimental.  This will replace gfxboot.com in the future.
65		* vesamenu.c32: new MENU RESOLUTION directive to set a screen
66		resolution other than 640x480.
67		* chain.c32: add support for loading isolinux.bin.
68		* chain.c32: make sure to always return to text mode.
69		* eltorito.sys: DOS driver for generic CD-ROMs; by Gary Tong
70		and Bart Lagerweij.
71
72		Changes in 3.83:
73		* PXELINUX: clear memory before handing over to a chainloaded
74		NBP.  This may help avoid a bug in Windows RIS.
75		* PXELINUX: fix localboot after NBP chainloading on certain
76		BIOSes (including ASUS A8N-E, but possibly others.)
77		* chain.c32: support chainloaded bootloaders on ISOLINUX.
78		* PXELINUX: allow filenames up to 251 characters.
79		* MEMDISK: fix problems booting from USB on Thinkpads, and
80		possibly other machines or hardware combinations.
81		* isohybrid: fix the -id option.
82		* HDT: updated to version 0.3.4.
83		* MEMDISK: the stack size is now configurable, with the stack=
84		option.
85		* Simple menu: fix Ctrl-W (word erase) in command-line edit.
86		* Simple menu: fix crash on some platforms.
87		* Gfxboot: fixes to the configuration file parsing.
88		* PXELINUX: add a tool to override specific DHCP options via
89		values hardcoded in the pxelinux.0 file.  These hardcoded
90		values can be either "before DHCP" (defaults if DHCP do not
91		provide values), or "after DHCP" (overrides DHCP).  The tool
92		pxelinux-options can be used to set these options.  This
93		feature does not apply to gpxelinux.0; when used with gPXE
94		this is better handled by modifying the embedded script.
95
96		Changes in 3.82:
97		* isohybrid: fix the -partok logic for loading from a partition.
98		* ISOLINUX: deal with systems which return from INT 13h with
99		interrupts disabled.
100		* Do not invoke the idle handler during large file loads.
101		* Simple menu: make ONTIMEOUT work with MENU HIDDEN.
102		* PXELINUX: handle TFTP servers which have extra NULs at the
103		end of an OACK packet.
104
105		Changes in 3.81:
106		* Shuffler: fix bug in real-mode entry.  This affected a
107		number of modules, probably in relatively unimportant ways,
108		but it completely broke linux.c32.
109		* Improved performance.
110		* Attempt to halt the processor while idle.  This can cause
111		bad reponsiveness when using a serial console especially for
112		automated input; if that ends up being a problem, use the
113		new "NOHALT 1" configuration command.
114		* linux.c32 now suppresses all messages if the "quiet" flag is
115		specified.
116		* isohybrid: add a variety of options, and a help message.
117		* ISOLINUX: fix booting in hybrid mode when CBIOS is used.
118		This unfortunately means that the isohybrid handoff protocol
119		has changed, so the isohybrid utility must version-match
120		isolinux.bin.
121		* Drop support for ACPI 3 extended memory flags.
122		* Menu system: don't set the autocr flag on the serial
123		console.
124		* altmbr: fix handling of logical partitions.
125		* altmbr: cap at 439 bytes so the partition select byte isn't
126		part of the file.
127
128		Changes in 3.80:
129		* New shuffler mechanism and API.
130		* Rewritten mboot.c32 module.
131		* The syslinux_boot_linux() function has been simplified.
132		* Don't hang trying to boot a "menu quit" label from the CLI.
133		* Fix problem with boot-once "sticking" on some BIOSes.
134		* isohybrid: fix problem with images over 2 GB in size.
135		* APM poweroff module (poweroff.com) by Sebastian Herbszt.
136		* ISOLINUX: fix the handling of large directories.  Bug found
137		and fixed by Steffen Winterfeldt.
138
139		Changes in 3.75:
140		* PXELINUX: fix the "keeppxe" option, which was broken in
141		3.74.
142		* MEMDISK: correct the extraction of geometry information from
143		the MBR of a hard disk image, again broken in 3.74.
144		* extlinux(1) man page from Brian Pellin.
145		* Simple menu: MENU SAVE is now controllable on a menu-by-menu
146		or entry-by-entry basis.
147		* gPXELINUX: fix interrupt-disabling bug.
148		* HDT: fix lockup on machines with certain PCI configurations.
149
150		Changes in 3.74:
151		* New UI directive, which allows a more natural way to specify
152		a menu system (or not.)  With the UI directive specifying
153		the menu system, the DEFAULT directive can be used to select
154		the default entry inside the menus.
155		* kbdmap.c32: new module to load a new keyboard map
156		dynamically.
157		* isohybrid: workaround bug in some versions of binutils.
158		* Fix issue with the placement of the initrd on some machines.
159		* ifcpu64: fix handling of less than three arguments.
160		* Fix bug in the shuffle library when dealing with a very
161		large number of fragments.
162		* Documentation fixes by Vicente Jimenez Aguilar.
163		* gPXE updated to version 0.9.7.
164		* hdt.c32: Hardware Detection Tool, an interactive hardware
165		analyzer module by Erwan Velu.
166		* MEMDISK: enable automatic determination of the disk geometry
167		for a large floppy disk image if (and only if) it is
168		formatted with a FAT filesystem.
169		* SYSLINUX: fix the handling of .bss files on FAT12/16.
170		* Suppress the Loading ... message if "quiet" is specified on
171		the kernel command line.
172		* Fix the use of "CONSOLE 0" with menu.c32.
173		* Allow COM32 modules to be aware of all memory even in the
174		presence of a memory hole.  The "linux.c32" module can be
175		used to load a kernel (or memdisk) plus large initrd on
176		such a system.
177		* MBR: produce alternate MBR variants which force the drive
178		number to hd0 (_f variants), or force the drive number to
179		hd0 if the Ctrl key is pressed (_c variants.)  Furthermore,
180		add an MBR variant (altmbr*.bin) which ignores the active
181		flag and instead boots the partition number specified in the
182		byte at offset 439 decimal.
183		* Add IPAPPEND strings to com32 modules, especially needed for
184		linux.c32.
185		* New MENU SAVE directive which saves the latest menu
186		selection until the next boot.  Currently only implemented for
187		EXTLINUX.
188		* gfxboot.com: *experimental* interface module to Steffen
189		Winterfeldt's "gfxboot" graphical front end
190		(http://gfxboot.sourceforge.net/).  Module by Sebastian Herbszt.
191
192		Changes in 3.73:
193		* Upgrade gPXE to release version 0.9.5.
194		* Fix a number of build errors on various platforms.
195		* Handle systems with E820 "extended attributes" per ACPI 3.
196		Someone "cleverly" decided to change the E820 spec in a
197		backwards-incompatible manner!
198		* MEMDISK: default to "safeint".
199		* Adopt the moniker "The Syslinux Project", standard proper
200		noun capitalization, to refer to the project as a whole.
201		Thus, reserve the all-caps "SYSLINUX" to refer to the FAT
202		loader.
203		* mboot.c32: add "-solaris" option to pass DHCP information to
204		the Solaris kernel; required for automatic Solaris boot
205		without using Solaris' pxeboot program.
206		* config.c32: trivial COM32 module to restart Syslinux with
207		another configuration file from the command line (equivalent
208		to the CONFIG command in the configuratin file.)
209
210		Changes in 3.72:
211		* Include the pxechain.com module from Jeffery Hutzelman at
212		Carnegie Mellon University.  This allows chaining another
213		PXE boot program while changing the DHCP packet passed to
214		it.
215		* Reorganize the Makefile system.
216		* Major PCI core cleanups and other source cleanup.
217		* gPXE code updated.
218		* Try to avoid memory-snooping attacks on passwords.  Note
219		that if someone has root on the box, they generally don't
220		need to compromise the boot loader...
221		* ISOLINUX: fix crash when given a zero-length file.
222		* sdi.c32: support gzipped SDI images.
223		* ISOLINUX: support generating images which can be either
224		a CD-ROM or a hard disk (USB disk, etc.)  See
225		doc/isolinux.txt for more information.
226		* Remote gdb support for COM32 modules; patch from Stefan
227		Hajnoczi.
228		* Support beeps in F-key help in the simple menu system.
229		* Tab display of labels, based on a patch from Sebastian
230		Herbszt.  Can be disabled with the NOCOMPLETE configuration
231		command.
232		* "menu default" can now be specified after "menu begin", to
233		indicate that a specific submenu should be the default entry.
234
235		Changes in 3.71:
236		* Workaround for a VESA BIOS which tries to make DOS system
237		calls(!!)
238		* Simple menu: fix navigation around disabled entries
239		(or at least try to...)
240		* EXTLINUX: proper error message when confused about mount
241		point.
242		* MEMDISK: be smarter about incompletely disabled floppies in
243		the BIOS and about being the only floppy.
244		* Optionally allow initrd to be specified on a separate line
245		rather than as part of the "append" line.  This is not
246		recommended, but apparently makes life easier for some
247		tools.
248		* SYSLINUX: if no config file is present, set the current
249		directory to the root directory (Sebastian Herbszt).
250		* chain.c32: option "hide" to support hiding and unhiding of
251		primary partitions on the boot drive with DOS, Win, or OS/2
252		partition types (01, 04, 06, 07, 0b, 0c, 0e).
253		* Unbreak the KBDMAP command (broken in 3.70).
254		* EXTLINUX: fix the handling of the ADV when using CBIOS.
255		* ifcpu64.c32: simple COM32 module to select a 32- or 64-bit
256		kernel (and optionally 32-bit kernels with or without PAE.)
257		Eventually we want a scripting language for this
258		kind of stuff; a Lua module is under development.
259		* Fix parsing of the SERIAL command without a baud rate
260		specified.
261		* chain.c32: error out when try to boot an unbootable
262		partition.
263		* SYSLINUX: when building the Win32 installer, search for
264		MinGW under a large number of possible names.
265
266		Changes in 3.70:
267		* PXELINUX: Support enhanced capabilities when running on top
268		of gPXE (http://www.etherboot.org/).  In particular, support
269		URL-style syntax for filenames, and any protocol that gPXE
270		supports (except, currently, iSCSI and AoE.)  This feature
271		is currently highly experimental.
272		* Substantial infrastructure changes to support files whose
273		length aren't known at open time (typically network
274		connections.)  Please note that the semantics of some of the
275		comboot APIs have changed slightly; please see doc/comboot.txt.
276		* PXELINUX: We no longer require a TFTP server which supports
277		the tsize option for all transfers.
278		* PXELINUX: Integrate with the gPXE source base; unified image
279		now included as "gpxelinux.0".
280		* The source tree has been restructured; files that were
281		previously in the root have moved into the core, dos, gpxe,
282		and utils directories.
283		* "make install", "make netinstall", and "make extbootinstall"
284		have been updated massively.  "make install-all" now installs
285		all three.
286		* Change default dir for auxiliary files from
287		/usr/lib/syslinux to /usr/share/syslinux.
288		* SYSLINUX: VFAT long filename support.
289		* MEMDISK: Any image less than 4096K (4 MB) is treated as a
290		floppy disk.  The geometry-guessing code will recognize all
291		common extended formats, but it is still possible some very
292		exotic formats need geometry specification.  Large floppies
293		and very small harddisks still need explicit specification.
294		* chain.c32: option "swap" to support swapping of BIOS drive
295		numbers.  This is necessary to boot certain operating systems
296		(DOS, Windows) from a secondary drive.
297		* chain.c32: option "file=" to support loading a boot file from
298		the SYSLINUX filesystem instead of loading the boot sector
299		from the drive.
300		* chain.c32: option "seg=" to control the load location.
301		* chain.c32: option "ntldr=" as a shorthand for "seg=0x2000
302		file="; use this to load one of WinNT's loaders:
303
304		chain.c32 hd0 1 ntldr=/MiniNT/setupldr.bin
305
306		Note that the file needs to be in the SYSLINUX filesystem.
307		* chain.32: options "freedos=" and "msdos="/"pcdos=" as
308		shorthands for "seg=0x60 file=" and "seg=0x70 file="
309		respectively; use this to load FreeDOS's kernel.sys, MS-DOS's
310		io.sys or PC-DOS's ibmbio.sys.
311		* Change to the A20 algorithm which *MIGHT* help systems that
312		have systems which freeze when Syslinux is used with USB
313		keyboards.  Note that this has been hard do verify, so I
314		would greatly appreciate feedback on it.
315		* Complex menu system: unbreak menus which has unnamed
316		submenus, like complex.c.
317		* Fix newline on the serial port for some com32 modules.
318		* chain.c32: support "boot" as the drive specification,
319		indicating the drive from which it was booted
320		(for syslinux/extlinux).
321		* SYSLINUX/EXTLINUX: support "localboot" with the same feature
322		set as ISOLINUX.
323		* Add an experimental MBR for GPT partition tables.
324		* Use $(CC) when determining compile flags.
325		* chain.c32: fix booting from logical partitions (Sergey
326		Vlasov.)
327
328		Changes in 3.63:
329		* Fix errors in the PCI and DMI detection modules (Erwan Velu,
330		Sebastian Herbszt).
331		* Fix host dependencies and other issues in the build system.
332		* PXELINUX: Allow class E addresses as unicast.
333		* sdi.c32: module to load Microsoft System Deployment Images.
334		For additional information, please see:
335		http://msdn2.microsoft.com/en-us/library/ms838543.aspx
336		* EXTLINUX: Correct reading directories with deleted entries.
337		* Shuffle library: correct the handling of certain geometries
338		(an upward move with source material blocking the move); as
339		required by sdi.c32 but theoretically possible for other
340		formats as well.
341		* Add "make netinstall" to install /tftpboot.
342		* Fix some documentation files that didn't get moved/renamed.
343
344		Changes in 3.62:
345		* Clean up garbage after "aborted." message.
346		* Clean up memdump.com filenames.
347		* Support SHA256 and SHA512 encrypted passwords.
348		* The shuffle library now can generate chained descriptors,
349		thus allowing pretty much arbitrarily complex memory maps.
350		* Handle command lines up to 2047 characters, the current
351		Linux kernel limit.
352		* vesamenu: support systems without linear framebuffer support
353		(sigh, what is this, 1993?) and 15-bit RGB modes.
354		* Move the label storage (for the command-line interface) to
355		high memory, removing the size limit and freeing up 64K of
356		low memory.
357		* Get rid of 4096-entry limit in the simple menu system.
358		* New hierarchial submenu support: see MENU BEGIN, MENU END,
359		MENU GOTO in doc/menu.txt.
360		* MENU QUIT allows creating a menu entry for returning to the
361		command line.
362		* ISOLINUX: Work around bug in certain Adaptec BIOSes,
363		patch by Bruce Robson.
364		* pngtopnm dependency removed from samples/ directory.
365		* Text documentation files (in doc/) renamed *.doc -> *.txt.
366
367		Changes in 3.61:
368		* EXTLINUX: fix crash when accessing an empty file.
369		* elf.c32: If a PHDR segment is present, load it.
370		* Fix SHA-1 and MD5 passwords.
371		* ISOLINUX: fix booting when mastered without
372		mkisofs -boot-info-table (broken since 3.50, sigh...)
373		* Handle BIOSes which emit multiple contiguous valid
374		memory regions in the e820 map.
375
376		Changes in 3.60:
377		* Support for "auxilliary data vector", a small amount of
378		writable storage.  Currently only supported for EXTLINUX,
379		but the infrastructure is there for the other derivatives,
380		assuming a suitable storage location can be found.
381		* EXTLINUX: boot-once support (--once, --clear-once, and
382		--reset-adv).
383		* A command is now required to the EXTLINUX installer, i.e. at
384		least one of --install, --update, --once, --clear-once, or
385		--reset-adv.
386
387		Changes in 3.55:
388		* PXELINUX: as per RFC 5071, PXELINUX no longer requires the
389		use of the magic cookie option (208) for unencapsulated
390		options.  Currently it does not require it for
391		vendor-encapsulated options (vendor-option-space) either,
392		but that MAY be reverted in the future if it causes
393		problems.
394		* Documentation text files moved to a common "doc" directory;
395		man pages from the Debian project added to the "man"
396		directory.
397		* Correct bug with self-overlapping memory areas when using
398		the shuffle interface.
399
400		Changes in 3.54:
401		* Add "menu separator", "menu indent", "menu disabled"
402		(see README.menu).
403		* vesamenu: fix handing of VESA modes with noncontiguous
404		memory buffers.  In particular, Qemu/KVM sets up such a mode
405		when Cirrus Logic emulation is enabled (which is the
406		default.)
407		* Support for calling real mode functions using far calls,
408		with argument on the stack.  This was implemented to support
409		the BIOS BBS specification, but subsequent experiments show
410		that the at least one of the most common BIOS cores, Award,
411		passes the presence check but doesn't actually implement the
412		functionality.
413
414		Changes in 3.53:
415		* Fix bugs related to the $PnP BIOS functionality on some
416		platforms.
417		* PXELINUX: Fix the "naked" version of :: (suppress prefix.)
418		* elf.c32: better error messages.
419		* Faster operation under Intel VT virtualization.
420		* PXELINUX: Fix DHCP bootfile option.
421		* mkdiskimage: Support more than 1024 cylinders.
422		* (Hopefully) fix installer on non-x86 platforms.
423		* Fix shuffle_and_boot_rm, used by linux.c32.
424		* Fix shuffle_and_boot_pm on 386/486.
425		* ISOLINUX (at least): fix bss memory overwrite hang.
426		* MBR: Fix booting from logical partitions.
427		* Code cleanups.
428
429		Changes in 3.52:
430		* Handle capitalized F-key commands in the menu system.
431		* Fix padding error when loading multiple ramdisks.
432		* Workaround for VMware crashing when trying to print a
433		message during early kernel boot (does not seem to work,
434		consider deleting.)
435		* chain.c32: add the ability to search for a specific MBR
436		signature at runtime.
437		* Fall back to the server identity option if the siaddr field
438		in the DHCP header isn't set.  This seems to match the
439		behaviour of most PXE stacks.
440		* mkdiskimage: give the generated disk image an MBR signature.
441		* MEMDISK: Fix failures on some BIOSes.
442		* Simple menu system: new "MENU HIDDEN" option to not display
443		the menu unless the user presses a key.
444		* Simple menu system: support MD5-encrypted passwords (modern
445		Unix standard style, with "$1$" prefixes.)
446		* pcitest.c32: now functions as a full "lspci".  Thanks to
447		Erwan Velu for this work.
448		* MEMDISK: Make EDD actually work.
449		* ISOLINUX: Fix for certain broken CD-ROM BIOSes which
450		randomly corrupted register FS.
451		* Simple menu system: fix memory overwrite bug that caused
452		some systems to lock up or behave weirdly.
453		* Fix building on 64-bit systems without a 32-bit libc installed.
454
455		Changes in 3.51:
456		* EXTLINUX: Fix failure to find the configuration file.
457
458		Changes in 3.50:
459		* New keywords allow the type of file to be specified in the
460		configuration file.
461		* It is now supported to load a different configuration file
462		with the CONFIG keyword.
463		* Fix API call 0x0019 (Read Disk.)
464		* MENU AUTOBOOT, MENU TABMSG, MENU PASSPROMPT allows
465		internationalization of menu messages.
466		* A new feature, TEXT HELP, allows the administrator to set
467		a multi-line help message for individual selections.
468		* Fix API call 0x0012 (Cleanup, shuffle and boot.)
469		* New API call "Cleanup, shuffle and boot to flat protected mode"
470		* New API call "Cleanup, shuffle and boot to real mode",
471		similar to API call 0x0012 but allows arbitrary register setting.
472		* Introduce a library interface for loading arbitrary binary
473		formats with relatively easily understood code.  See
474		the elf.c32 module for an example on how to use it.
475		* New module "elf.c32", to load a protected-mode ELF kernel.
476		* MBR (old and new): Fix bug in CHS mode when LBA >
477		65535*sectors.
478		* vesamenu: fix decoding of palettized PNG images.
479		* Update the Linux kernel boot protocol.
480		* PXELINUX: Press Ctrl-N at the boot prompt to read out the
481		network info.
482		* Instead of the (non-existent) MAC, use the client identifier
483		for networks like Infiniband and Firewire/1394.
484		* Add a new INCLUDE command to the core syslinux parser.
485		* Allow binding help text to F11 and F12.
486		* F-key help now available in the simple menu system.
487		* Disabled the polling for ARP during idle.  It is simply too
488		slow on some (broken!) PXE stacks.
489		* PXELINUX: also try to fetch the config file based on UUID.
490		* SYSLINUX/EXTLINUX: New RAID mode (-r) which calls the BIOS
491		to load the next device (typically the next drive) on boot
492		failure.
493
494		Changes in 3.36:
495		* MEMDISK: Disable EDD by default on floppy disks.  EDD can be
496		enabled with the "edd" option and disabled with "noedd".
497		This (hopefully) should make Ghost work again.
498		* SYSLINUX: "unix" installer now uses Linux ioctls instead of
499		using libfat.
500		* New MBR which can boot from logical partitions.
501		* SYSLINUX: Fix bug in detecting special extensions which was
502		introduced in 3.35 :(
503		* PXELINUX: Unbreak chainbooting FreeBSD (and possibly others.)
504
505		Changes in 3.35:
506		* MEMDISK: New "safeint" mode.
507		* MEMDISK: Be more compliant with the PnP BIOS spec.
508		* MEMDISK: Turn on EDD support by default.
509		* MEMDISK: Try to work on some machines on which it would not
510		work when there was no floppy drive in the system.
511		* Simple menu system: fix serial console support (broken in
512		3.30).
513		* SYSLINUX: Support subdirectories.  Like ISOLINUX, the
514		"current directory" is the directory in which syslinux.cfg
515		is found; this is searched for in the sequence
516		/boot/syslinux, /syslinux, /.  As a side benefit, label names
517		like "linux-2.6.18" and "linux-2.6.19" are now supported.
518
519		To install ldlinux.sys in a subdirectory, pass the -d
520		directory option to the SYSLINUX installer.
521
522		This work was sponsored by slax.org (thanks, Tomas!)
523		* New API call: read disk.
524		* Invoke ONERROR on initrd load failure.
525
526		Changes in 3.31:
527		* The simple menu system (menu.c32 and vesamenu.c32) now
528		support loading more than one configuration file at a time,
529		using MENU INCLUDE or by specifying multiple filenames.
530		* The MENU COLOR statement can now control the shadowing mode.
531
532		Changes in 3.30:
533		* libcom32 extended to support graphics mode and graphical console.
534		* vesamenu.c32, new graphical version of the Simple
535		Menu System, see README.menu.
536		* New com32 modules by Erwan Velu do selection based on CPUID
537		or PCI devices present.
538		* RPM spec: add syslinux-tftpboot module; move syslinux by
539		default to the /usr/share/syslinux directory.
540		* RPM spec: extlinux is now a separate package.
541
542		Changes in 3.20:
543		* EXTLINUX: New options --install (-i) and --update (-U), to
544		make it clear if a boot loader should be installed or
545		updated.  For now, defaults to --install for compatibility;
546		a future version will require one of these options.
547		* New library functions to load and place files in memory.
548		* mboot.c32 bug fixes.
549		* Remove 8 MB kernel size restriction.
550		* Add "klibc" target for building unix/syslinux and
551		extlinux/extlinux with klcc (klibc-1.4.27 or later.)
552		* PXELINUX: Fail (and eventually reboot) if no configuration
553		file was found.
554		* COM32 module by Erwan Velu to make decisions based on DMI
555		info.
556		* Fix issue where going back and forth between menus a lot
557		would cause a hang.
558		* ISOLINUX: Fix bug which made "cd boot sectors" not work.
