1 Starting with 1.47, changes marked with SYSLINUX/PXELINUX/ISOLINUX
2 apply to that specific program only; other changes apply to all of
3 them.
5 Changes in 3.71:
6 * Workaround for a VESA BIOS which tries to make DOS system
7 calls(!!)
8 * Simple menu: fix navigation around disabled entries
9 (or at least try to...)
10 * EXTLINUX: proper error message when confused about mount
11 point.
12 * MEMDISK: be smarter about incompletely disabled floppies in
13 the BIOS and about being the only BIOS.
14 * Optionally allow initrd to be specified on a separate line
15 rather than as part of the "append" line. This is not
16 recommended, but apparently makes life easier for some
17 tools.
18 * SYSLINUX: if no config file is present, set the current
19 directory to the root directory (Sebastian Herbszt.)
20 * chain.c32: option "hide" to support hiding and unhiding of
21 primary partitions on the boot drive with DOS, Win, or OS/2
22 partition types (01, 04, 06, 07, 0b, 0c, 0e).
23 * Unbreak the KBDMAP command (broken in 3.70).
24 * EXTLINUX: fix the handling of the ADV when using CBIOS.
25 * ifcpu64.c32: simple COM32 module to select a 32- or 64-bit
26 kernel (and optionally 32-bit kernels with or without PAE.)
27 Eventually we want a scripting language for this
28 kind of stuff...
30 Changes in 3.70:
31 * PXELINUX: Support enhanced capabilities when running on top
32 of gPXE (http://www.etherboot.org/). In particular, support
33 URL-style syntax for filenames, and any protocol that gPXE
34 supports (except, currently, iSCSI and AoE.) This feature
35 is currently highly experimental.
36 * Substantial infrastructure changes to support files whose
37 length aren't known at open time (typically network
38 connections.) Please note that the semantics of some of the
39 comboot APIs have changed slightly; please see doc/comboot.txt.
40 * PXELINUX: We no longer require a TFTP server which supports
41 the tsize option for all transfers.
42 * PXELINUX: Integrate with the gPXE source base; unified image
43 now included as "gpxelinux.0".
44 * The source tree has been restructured; files that were
45 previously in the root have moved into the core, dos, gpxe,
46 and utils directories.
47 * "make install", "make netinstall", and "make extbootinstall"
48 have been updated massively. "make install-all" now installs
49 all three.
50 * Change default dir for auxiliary files from
51 /usr/lib/syslinux to /usr/share/syslinux.
52 * SYSLINUX: VFAT long filename support.
53 * MEMDISK: Any image less than 4096K (4 MB) is treated as a
54 floppy disk. The geometry-guessing code will recognize all
55 common extended formats, but it is still possible some very
56 exotic formats need geometry specification. Large floppies
57 and very small harddisks still need explicit specification.
58 * chain.c32: option "swap" to support swapping of BIOS drive
59 numbers. This is necessary to boot certain operating systems
60 (DOS, Windows) from a secondary drive.
61 * chain.c32: option "file=" to support loading a boot file from
62 the SYSLINUX filesystem instead of loading the boot sector
63 from the drive.
64 * chain.c32: option "seg=" to control the load location.
65 * chain.c32: option "ntldr=" as a shorthand for "seg=0x2000
66 file="; use this to load one of WinNT's loaders:
68 chain.c32 hd0 1 ntldr=/MiniNT/setupldr.bin
70 Note that the file needs to be in the SYSLINUX filesystem.
71 * chain.32: options "freedos=" and "msdos="/"pcdos=" as
72 shorthands for "seg=0x60 file=" and "seg=0x70 file="
73 respectively; use this to load FreeDOS's kernel.sys, MS-DOS's
74 io.sys or PC-DOS's ibmbio.sys.
75 * Change to the A20 algorithm which *MIGHT* help systems that
76 have systems which freeze when Syslinux is used with USB
77 keyboards. Note that this has been hard do verify, so I
78 would greatly appreciate feedback on it.
79 * Complex menu system: unbreak menus which has unnamed
80 submenus, like complex.c.
81 * Fix newline on the serial port for some com32 modules.
82 * chain.c32: support "boot" as the drive specification,
83 indicating the drive from which it was booted
84 (for syslinux/extlinux).
85 * SYSLINUX/EXTLINUX: support "localboot" with the same feature
86 set as ISOLINUX.
87 * Add an experimental MBR for GPT partition tables.
88 * Use $(CC) when determining compile flags.
89 * chain.c32: fix booting from logical partitions (Sergey
90 Vlasov.)
92 Changes in 3.63:
93 * Fix errors in the PCI and DMI detection modules (Erwan Velu,
94 Sebastian Herbszt).
95 * Fix host dependencies and other issues in the build system.
96 * PXELINUX: Allow class E addresses as unicast.
97 * sdi.c32: module to load Microsoft System Deployment Images.
98 For additional information, please see:
99 http://msdn2.microsoft.com/en-us/library/ms838543.aspx
100 * EXTLINUX: Correct reading directories with deleted entries.
101 * Shuffle library: correct the handling of certain geometries
102 (an upward move with source material blocking the move); as
103 required by sdi.c32 but theoretically possible for other
104 formats as well.
105 * Add "make netinstall" to install /tftpboot.
106 * Fix some documentation files that didn't get moved/renamed.
108 Changes in 3.62:
109 * Clean up garbage after "aborted." message.
110 * Clean up memdump.com filenames.
111 * Support SHA256 and SHA512 encrypted passwords.
112 * The shuffle library now can generate chained descriptors,
113 thus allowing pretty much arbitrarily complex memory maps.
114 * Handle command lines up to 2047 characters, the current
115 Linux kernel limit.
116 * vesamenu: support systems without linear framebuffer support
117 (sigh, what is this, 1993?) and 15-bit RGB modes.
118 * Move the label storage (for the command-line interface) to
119 high memory, removing the size limit and freeing up 64K of
120 low memory.
121 * Get rid of 4096-entry limit in the simple menu system.
122 * New hierarchial submenu support: see MENU BEGIN, MENU END,
123 MENU GOTO in doc/menu.txt.
124 * MENU QUIT allows creating a menu entry for returning to the
125 command line.
126 * ISOLINUX: Work around bug in certain Adaptec BIOSes,
127 patch by Bruce Robson.
128 * pngtopnm dependency removed from samples/ directory.
129 * Text documentation files (in doc/) renamed *.doc -> *.txt.
131 Changes in 3.61:
132 * EXTLINUX: fix crash when accessing an empty file.
133 * elf.c32: If a PHDR segment is present, load it.
134 * Fix SHA-1 and MD5 passwords.
135 * ISOLINUX: fix booting when mastered without
136 mkisofs -boot-info-table (broken since 3.50, sigh...)
137 * Handle BIOSes which emit multiple contiguous valid
138 memory regions in the e820 map.
140 Changes in 3.60:
141 * Support for "auxilliary data vector", a small amount of
142 writable storage. Currently only supported for EXTLINUX,
143 but the infrastructure is there for the other derivatives,
144 assuming a suitable storage location can be found.
145 * EXTLINUX: boot-once support (--once, --clear-once, and
146 --reset-adv).
147 * A command is now required to the EXTLINUX installer, i.e. at
148 least one of --install, --update, --once, --clear-once, or
149 --reset-adv.
151 Changes in 3.55:
152 * PXELINUX: as per RFC 5071, PXELINUX no longer requires the
153 use of the magic cookie option (208) for unencapsulated
154 options. Currently it does not require it for
155 vendor-encapsulated options (vendor-option-space) either,
156 but that MAY be reverted in the future if it causes
157 problems.
158 * Documentation text files moved to a common "doc" directory;
159 man pages from the Debian project added to the "man"
160 directory.
161 * Correct bug with self-overlapping memory areas when using
162 the shuffle interface.
164 Changes in 3.54:
165 * Add "menu separator", "menu indent", "menu disabled"
166 (see README.menu).
167 * vesamenu: fix handing of VESA modes with noncontiguous
168 memory buffers. In particular, Qemu/KVM sets up such a mode
169 when Cirrus Logic emulation is enabled (which is the
170 default.)
171 * Support for calling real mode functions using far calls,
172 with argument on the stack. This was implemented to support
173 the BIOS BBS specification, but subsequent experiments show
174 that the at least one of the most common BIOS cores, Award,
175 passes the presence check but doesn't actually implement the
176 functionality.
178 Changes in 3.53:
179 * Fix bugs related to the $PnP BIOS functionality on some
180 platforms.
181 * PXELINUX: Fix the "naked" version of :: (suppress prefix.)
182 * elf.c32: better error messages.
183 * Faster operation under Intel VT virtualization.
184 * PXELINUX: Fix DHCP bootfile option.
185 * mkdiskimage: Support more than 1024 cylinders.
186 * (Hopefully) fix installer on non-x86 platforms.
187 * Fix shuffle_and_boot_rm, used by linux.c32.
188 * Fix shuffle_and_boot_pm on 386/486.
189 * ISOLINUX (at least): fix bss memory overwrite hang.
190 * MBR: Fix booting from logical partitions.
191 * Code cleanups.
193 Changes in 3.52:
194 * Handle capitalized F-key commands in the menu system.
195 * Fix padding error when loading multiple ramdisks.
196 * Workaround for VMware crashing when trying to print a
197 message during early kernel boot (does not seem to work,
198 consider deleting.)
199 * chain.c32: add the ability to search for a specific MBR
200 signature at runtime.
201 * Fall back to the server identity option if the siaddr field
202 in the DHCP header isn't set. This seems to match the
203 behaviour of most PXE stacks.
204 * mkdiskimage: give the generated disk image an MBR signature.
205 * MEMDISK: Fix failures on some BIOSes.
206 * Simple menu system: new "MENU HIDDEN" option to not display
207 the menu unless the user presses a key.
208 * Simple menu system: support MD5-encrypted passwords (modern
209 Unix standard style, with "$1$" prefixes.)
210 * pcitest.c32: now functions as a full "lspci". Thanks to
211 Erwan Velu for this work.
212 * MEMDISK: Make EDD actually work.
213 * ISOLINUX: Fix for certain broken CD-ROM BIOSes which
214 randomly corrupted register FS.
215 * Simple menu system: fix memory overwrite bug that caused
216 some systems to lock up or behave weirdly.
217 * Fix building on 64-bit systems without a 32-bit libc installed.
219 Changes in 3.51:
220 * EXTLINUX: Fix failure to find the configuration file.
222 Changes in 3.50:
223 * New keywords allow the type of file to be specified in the
224 configuration file.
225 * It is now supported to load a different configuration file
226 with the CONFIG keyword.
227 * Fix API call 0x0019 (Read Disk.)
228 * MENU AUTOBOOT, MENU TABMSG, MENU PASSPROMPT allows
229 internationalization of menu messages.
230 * A new feature, TEXT HELP, allows the administrator to set
231 a multi-line help message for individual selections.
232 * Fix API call 0x0012 (Cleanup, shuffle and boot.)
233 * New API call "Cleanup, shuffle and boot to flat protected mode"
234 * New API call "Cleanup, shuffle and boot to real mode",
235 similar to API call 0x0012 but allows arbitrary register setting.
236 * Introduce a library interface for loading arbitrary binary
237 formats with relatively easily understood code. See
238 the elf.c32 module for an example on how to use it.
239 * New module "elf.c32", to load a protected-mode ELF kernel.
240 * MBR (old and new): Fix bug in CHS mode when LBA >
241 65535*sectors.
242 * vesamenu: fix decoding of palettized PNG images.
243 * Update the Linux kernel boot protocol.
244 * PXELINUX: Press Ctrl-N at the boot prompt to read out the
245 network info.
246 * Instead of the (non-existent) MAC, use the client identifier
247 for networks like Infiniband and Firewire/1394.
248 * Add a new INCLUDE command to the core syslinux parser.
249 * Allow binding help text to F11 and F12.
250 * F-key help now available in the simple menu system.
251 * Disabled the polling for ARP during idle. It is simply too
252 slow on some (broken!) PXE stacks.
253 * PXELINUX: also try to fetch the config file based on UUID.
254 * SYSLINUX/EXTLINUX: New RAID mode (-r) which calls the BIOS
255 to load the next device (typically the next drive) on boot
256 failure.
258 Changes in 3.36:
259 * MEMDISK: Disable EDD by default on floppy disks. EDD can be
260 enabled with the "edd" option and disabled with "noedd".
261 This (hopefully) should make Ghost work again.
262 * SYSLINUX: "unix" installer now uses Linux ioctls instead of
263 using libfat.
264 * New MBR which can boot from logical partitions.
265 * SYSLINUX: Fix bug in detecting special extensions which was
266 introduced in 3.35 :(
267 * PXELINUX: Unbreak chainbooting FreeBSD (and possibly others.)
269 Changes in 3.35:
270 * MEMDISK: New "safeint" mode.
271 * MEMDISK: Be more compliant with the PnP BIOS spec.
272 * MEMDISK: Turn on EDD support by default.
273 * MEMDISK: Try to work on some machines on which it would not
274 work when there was no floppy drive in the system.
275 * Simple menu system: fix serial console support (broken in
276 3.30).
277 * SYSLINUX: Support subdirectories. Like ISOLINUX, the
278 "current directory" is the directory in which syslinux.cfg
279 is found; this is searched for in the sequence
280 /boot/syslinux, /syslinux, /. As a side benefit, label names
281 like "linux-2.6.18" and "linux-2.6.19" are now supported.
283 To install ldlinux.sys in a subdirectory, pass the -d
284 directory option to the SYSLINUX installer.
286 This work was sponsored by slax.org (thanks, Tomas!)
287 * New API call: read disk.
288 * Invoke ONERROR on initrd load failure.
290 Changes in 3.31:
291 * The simple menu system (menu.c32 and vesamenu.c32) now
292 support loading more than one configuration file at a time,
293 using MENU INCLUDE or by specifying multiple filenames.
294 * The MENU COLOR statement can now control the shadowing mode.
296 Changes in 3.30:
297 * libcom32 extended to support graphics mode and graphical console.
298 * vesamenu.c32, new graphical version of the Simple
299 Menu System, see README.menu.
300 * New com32 modules by Erwan Velu do selection based on CPUID
301 or PCI devices present.
302 * RPM spec: add syslinux-tftpboot module; move syslinux by
303 default to the /usr/share/syslinux directory.
304 * RPM spec: extlinux is now a separate package.
306 Changes in 3.20:
307 * EXTLINUX: New options --install (-i) and --update (-U), to
308 make it clear if a boot loader should be installed or
309 updated. For now, defaults to --install for compatibility;
310 a future version will require one of these options.
311 * New library functions to load and place files in memory.
312 * mboot.c32 bug fixes.
313 * Remove 8 MB kernel size restriction.
314 * Add "klibc" target for building unix/syslinux and
315 extlinux/extlinux with klcc (klibc-1.4.27 or later.)
316 * PXELINUX: Fail (and eventually reboot) if no configuration
317 file was found.
318 * COM32 module by Erwan Velu to make decisions based on DMI
319 info.
320 * Fix issue where going back and forth between menus a lot
321 would cause a hang.
322 * ISOLINUX: Fix bug which made "cd boot sectors" not work.
324 Changes in 3.11:
325 * MEMDISK: Fix bug by which accessing the real floppy disk
326 as B: in MS-DOS was broken.
327 * Simple menu system: allow tweaking of the screen layout.
328 * Simple menu system: better command-line editing, correctly
329 handle command lines above 256 characters.
330 * PXELINUX: revert memory allocation change that caused
331 problems on some network cards.
332 * MEMDISK: Try work around a bug on some BIOSes when no
333 physical floppy disk is present in the system.
334 * Enable the 16550A FIFOs, if present, when doing serial
335 console.
336 * New "totaltimeout" command establishes a timeout without
337 regard for any user input.
338 * Simple menu system: timeout behaviour now more in line with
339 user expectations.
340 * Simple menu system: "ontimeout" should now work correctly.
342 Changes in 3.10:
343 * gcc 4.0.1 compilation fixes.
344 * Add support for querying the PCI BIOS in libcom32
345 (used by ethersel et al.)
346 * Fix PCI handing (ethersel etc) on several old chipsets (and
347 VMWare.)
348 * Try to deal with systems with broken EBIOS.
349 * New API call to do "localboot".
350 * New API call to query features.
351 * New API call to run kernel image, a lower-level call than
352 "run command". See comboot.doc.
353 * Fix for bug in EBIOS code discovered by Arwin Vosselman.
354 * NOESCAPE security fix.
355 * Comments are now recognized even without a space following #.
356 * Fix incorrect handling of mixes of entries with and without
357 MENU PASSWD.
358 * The idle API call now harmlessly returns failure if it is a
359 no-op. That way the caller can decide whether or not to
360 bother invoking it again.
361 * Temporarily disable the idle API call on PXELINUX, due to
362 some platforms on which the idle API call seems to hang; this
363 problem has not yet been debugged.
364 * MEMDISK: the handling of DOSEMU-headered images was broken;
365 fix it.
366 * EXTLINUX: symlinks are now supported.
367 * Simple menu system: N and P now work correctly as hotkeys.
368 * MEMDISK: more BIOS bug workarounds.
370 Changes in 3.09:
371 * gcc4 compilation fix.
372 * <BEL> (Ctrl-G) in message files now causes a beep.
373 * Reduce the command line to 511 characters; 1023 caused
374 memory overflows.
376 Changes in 3.08:
377 * SYSLINUX: Fix performance regression (-s mode always
378 enabled.)
379 * Add API function for idle loop.
380 * libutil: Add do_idle() function for idle loop, make
381 get_key() use it.
382 * libutil: Add SHA-1 and base64 functions.
383 * Simple menu system: add password support.
384 * EXTLINUX: Sparse files now handled correctly.
385 * EXTLINUX: Large directories now handled correctly.
386 * ALL: At the prompt, Ctrl-X now forces text mode.
387 * Fix configuration file parsing error, that could cause
388 hangs.
389 * Rewritten advanced menuing system from Murali Ganapathy.
390 * MEMDISK: New "bigraw" mode to work around certain broken
391 BIOS flash programs.
392 * COM32 module to boot Multiboot systems, including Xen. See
393 com32/modules/mboot.doc.
394 * Max command line changed to 1023 characters. Note that the
395 kernel proper still can only handle 255 characters without
396 patching, and COM16 binaries can only handle 125 characters.
398 Changes in 3.07:
399 * Fix chainloading (chain.c32).
400 * Fix zlib build problem.
401 * Use a private copy of <linux/ext2_fs.h>.
403 Changes in 3.06:
404 * Fix typo that caused the ramdisk to load in the wrong place.
406 Changes in 3.05:
407 * New API function "shuffle and boot"; allows COM32 modules to
408 load or construct (almost) arbitrarily complex objects,
409 e.g. a kernel and its initrd/initramfs in pieces, and have
410 the API core reorganize memory for booting. (A library API
411 for this function will be introduced in a later version.)
412 * The initrd= option now supports multiple filenames separated
413 by commas. This is mostly useful for initramfs, which can
414 be composed of multiple separate cpio or cpio.gz archives.
415 (Note: all files except the last one are zero-padded to a 4K
416 page boundary. This should not affect initramfs.)
417 * EXTLINUX: Fix API function 000Ah (get derivative-specific
418 info).
419 * libcom32/ethersel: Support PCI Config Mechanism #2 on
420 machines still infested with that hideous old hack.
421 * SYSLINUX: Fix directory-parsing bug.
423 Changes in 3.02:
424 * SYSLINUX: The "unix" installer now sets the MS-DOS
425 attributes (hidden, system, readonly.)
426 * COM32 library: build the .lnx (test modules for running
427 under Linux) as architecture native modules, in case
428 i386 devel libraries aren't installed.
429 * EXTLINUX: Hack for systems which don't have BLKGETSIZE64
430 defined in the standard header files.
431 * Simple menu system: minor aestetic improvements, and try to
432 work better over a serial console (speed, and readability on
433 monochrome terminal emulators.)
434 * New CONSOLE directive to control output on the video console
435 (useful for dealing with some broken serial-forwarding
436 BIOSes.)
437 * New com32 module "ethersel" for searching for an Ethernet
438 card and selecting the proper version of Etherboot.
439 * EXTLINUX: Allow the user to override the detected geometry.
440 Add help.
442 Changes in 3.01:
443 * EXTLINUX, SYSLINUX: Fix compile errors on some systems.
444 * EXTLINUX: Default to zipdrive geometry (64 heads, 32
445 sectors) if no other geometry can be detected.
447 Changes in 3.00:
448 * SYSLINUX: Support FAT32 and EDD. As an unfortunate
449 consequence, LDLINUX.SYS is no longer an ordinary file; it
450 is block-mapped at install time, which means it can only be
451 written using the syslinux installers.
452 * SYSLINUX: Reorganize the source code for the installers;
453 each one of the installers (dos, win32, unix, mtools) is now
454 built in its own subdirectory. In particular, "mtools" is
455 the unprivileged installer which uses mtools; "unix" is the
456 privileged installer which uses system calls.
457 * SYSLINUX: Completely rewritten DOS installer in C.
458 * ALL: "label" statement information is now stored in a
459 compressed format, which means that a lot more labels are
460 permitted (500-1000 in a typical configuration, but depends
461 on the complexity.)
462 * EXTLINUX: New derivative, which boots from an ext2/ext3
463 filesystem.
464 * SYSLINUX: The DOS and Win32 installers can now optionally
465 write the boot sector to a file instead of the real boot
466 sector. This is not supported in the Linux installers,
467 however.
468 * ALL: New NOESCAPE command, disables the "hold down the Shift
469 key to display the prompt" behaviour.
470 * New simple menu system, as an alternative to the advanced
471 menu system already present. See README.menu for details.
472 * PXELINUX: Filenames can now be prefixed with an IP address
473 or DNS name plus :: (e.g. 192.0.2.1::filename or
474 server.domain.com::filename), which downloads a file from an
475 alternate TFTP server, or just a :: (e.g. ::filename), which
476 suppresses the common pathname prefix. See pxelinux.doc.
477 * SYSLINUX: Add an -m option to the DOS and Win32 installers
478 to write an MBR and -a to mark the partition SYSLINUX is
479 being installed on active.
480 * MEMDISK: Give a way to query the boot loader type while
481 running MEMDISK; see memdisk/memdisk.doc and
482 sample/mdiskchk.c.
483 * mkdiskimage: substantially improved mkdiskimage which, among
484 other things, can now be used to initialize USB keys as
485 zipdrives; see README.usbkey for more information.
487 Changes in 2.13:
488 * MEMDISK: Fix command-line parsing "brown paper bag" class
489 bug.
490 * MEMDISK: Add "raw" mode to support the DOS boot disk from
491 WinME/XP, which seems to deliberately crash the system
492 when someone uses the "INT 15h mover" highmem API.
493 * Make "make install" do something sane for the com32
494 development environment.
495 * In the spec file, create a separate -devel RPM for the com32
496 development environment.
498 Changes in 2.12:
499 * Simple C library, based on klibc, for writing COM32
500 programs.
501 * Fix the handling of file length in loading of COM32
502 programs.
503 * MEMDISK: Work around a linker bug by rearranging the code to
504 not use the linker for the 16-bit code.
505 * SYSLINUX: If we're building on a machine without a Win32
506 (mingw) compiler, just skip building syslinux.exe.
507 * ISOLINUX: Support non-mkisofs mastering programs, at least
508 as long as the image is single-session. For best results,
509 ISOLINUX should be the only boot loader installed.
510 * MEMDISK: Allow the user to specify that the simulated disk
511 should be write-protected.
513 Changes in 2.11:
514 * ALL: Add an API call to get the configuration file name.
515 * SYSLINUX: Fix bug in 2.10 that prevented it from working
516 correctly for a lot of people.
517 * SYSLINUX: In the installer, make mtools a bit less fussy.
518 * Make the menu system compile with newer gcc's.
520 Changes in 2.10:
521 * MEMDISK: Handle images compressed with zip as well as with
522 gzip. Some Windows-based image tools apparently generate
523 these kinds of images by default. Patch by Patrick
524 LoPresti.
525 * Major menu improvement from Murali Ganapathy.
526 * ISOLINUX: Wonderfully sick and brilliant workaround for
527 severe bugs in certain Award BIOSes; from Knut Petersen.
528 * SYSLINUX: Fix for the nomtools installed, from Frederic
529 Pasteleurs.
530 * PXELINUX: Fix handling of IP numbers in the ranges
531 100-109 and 200-209.
532 * ALL: New option "allowoptions" (defaults to 1), which
533 controls if options are allowed on the command line or not.
534 * SYSLINUX: Support building under klibc (see the klibc
535 distribution for details.)
537 Changes in 2.09:
538 * SYSLINUX: Remove residual setuid crap from
539 syslinux-nomtools.
540 * Handle video pages correctly when using the API functions.
541 * Handle compiling on an x86-64 platform correctly.
542 * Menu system from Murali Krishnan Ganapathy; see the menu
543 directory for information.
544 * COMBOOT: Allow COMBOOT programs to change screen text mode.
545 * COMBOOT: Correct the documentation of how to detect
546 SYSLINUX from COMBOOT!!!!
547 * COMBOOT: Fix "get key without echo" API function.
548 * SYSLINUX: Fix bug that affected the API open function.
549 * ALL: Improve the E820 memory parser, to work around some
550 buggy BIOSes.
552 Changes in 2.08:
553 * Add new configuration command "ontimeout" to allow timeout
554 to have a different action than just pressing Enter.
555 * Add new configuration command "onerror" to allow a custom
556 command to be executed in case the kernel image is not found.
557 * Fix bugs in the COMBOOT/COM32 command-line parsing. APPEND
558 now works with COMBOOT/COM32 images.
559 * PXELINUX: Poll for ARP requests while sitting at the
560 prompt. This makes some boot servers a lot less unhappy.
561 * PXELINUX: Actually free sockets when we get a failure
562 (including file not found.) This bug would cause us to run
563 out of sockets and thus "go deaf" after a while.
564 * MEMDISK: Add an API to query for the existence of MEMDISK.
565 * SYSLINUX: Fix loading boot sectors (.bs/.bss) from floppy
566 disk.
567 * .c32 is now one of the extensions searched for
568 automatically.
569 * PXELINUX: RFBG.exe seems to randomly overwrite memory
570 location 0x5700. Thus, don't use it!
571 * PXELINUX: Change pathname length max from 63 to 127; change
572 max vkernels from 128 to 64.
573 * Support Ctrl-U -> kill entire command line input.
574 * The "samples" directory contains a (barely at all tested)
575 chain loading example, chain.c32, which may be used to
576 chainload local floppy disks and hard disks. Use with
577 "chain fdN" or "chain hdN [partition]"; N = 0 for the first
578 drive of each type.
580 Changes in 2.07:
581 * MEMDISK: Workaround for BIOSes which go into a snit when
582 they get a RESET command for the floppy system when there is
583 no floppy in the system.
584 * PXELINUX: Add "ipappend 2", which passes the hardware
585 address of the boot interface to the kernel as a
586 command-line option.
587 * mkdiskimage: fix the generation of the end limit.
588 * PXELINUX: Fix multiple bugs in chainloading of other NBPs.
589 * MEMDISK: Fix bug that would occationally cause "ran out of
590 input data" when using compressed disk images.
591 * SYSLINUX: Updates for the win32 installer (from Lars Munch.)
592 * PXELINUX: PXELINUX-specific options are now recognized both
593 in a vendor-option-space (a.k.a. type 43 encapsulated) as
594 well as in a site-option-space (unencapsulated.)
595 * COM32: Don't crash when DS != 0.
596 * COMBOOT/COM32: Make file reading work correctly. Thanks to
597 Phung Chi Kien for submitting a test program.
599 Changes in 2.06:
600 * ALL: Fix problem that would occationally cause a
601 boot failure, depending on the length of the kernel.
602 * ISOLINUX: Fix problem that would occationally cause a
603 boot failure, depending on the length of directories.
604 * SYSLINUX: Win32 installer now flushes buffers.
605 * ppmtolss16: Be fully compliant with the PNM spec;
606 actually process comments in the header and odd
607 alignments of the various parameters, as well as
608 "plain" (not raw) files and PBM and PGM files.
609 * PXELINUX: Lower the default MTU to 1472 in order to deal
610 with systems with slightly nonstandard MTUs, and PXE
611 stacks which don't defragment correctly. Unfortunately this
612 is very hard to test dynamically.
614 Changes in 2.05:
615 * PXELINUX: Add a default query based on the hardware address
616 of the boot device. This is in lower case hexadecimal form
617 separated by dashes and including the hardware type, for
618 example, the Ethernet (type 1) address 88:99:AA:BB:CC:DD
619 would query the file pxelinux.cfg/01-88-99-aa-bb-cc-dd.
620 * PXELINUX: Fix bug involving non-IP-based config file names.
621 * SYSLINUX: New installer for WinNT-based systems, from Lars
622 Munch.
623 * MEMDISK: Fix handling of memory region overlap when
624 decompressing. Thanks to Mikhail Kupchik for identifying
625 the problem.
627 Changes in 2.04:
628 * ALL: Reclaim even more low memory by observing that
629 comboot_seg == real_mode_seg is perfectly fine, and by the
630 fact that the 1000h segment managed to get unused in all
631 derivatives...
632 * PXELINUX: Attempt to negotiate full Ethernet-sized blocks
633 (1468 bytes) using the blksize option.
634 * SYSLINUX: Resurrect the old no-mtools version of the
635 installer, although as a root-only tool. Some distributors
636 have indicated that they need a small standalone installer.
637 * MEMDISK: Fix a memory offset computation error when
638 installing compressed disks which generally would cause
639 1 MB of memory to be wasted.
640 * MEMDISK: Fix installing the E820 memory map. Calling
641 INT 15h AX=0E820h with MEMDISK 2.03 loaded would give a
642 completely corrupt memory map.
643 * SYSLINUX: Make libsyslinux a dynamic library, so that it can
644 be updated separately from client programs. The whole idea,
645 after all, is to enable alternate programs to become
646 syslinux installers.
647 * Include an rpm spec file in the distribution, so rpmbuild
648 -ta works.
650 Changes in 2.03:
651 * Actually support comment lines in the configuration file.
652 * PXELINUX: Try to resolve some problems with stack switches.
653 * PXELINUX: Handle PXE stacks with broken routing.
654 With these workarounds, the remote install PXE boot floppy
655 (rbfg.exe) from Argon Technologies should work correctly.
656 * Fix problems with Perl scripts in UTF-8 locales.
657 * You probably need NASM 0.98.34 or later to compile this
658 version. 0.98.36 is recommended.
659 * MEMDISK: Now supports gzip compressed images.
661 Changes in 2.02:
662 * SYSLINUX: Security flaws have been found in the SYSLINUX
663 installer when running setuid root. Rewrite the SYSLINUX
664 installer so it uses mtools instead. It therefore now
665 requires mtools (specifically mcopy and mattrib) to exist on
666 your system, but it will not require root privileges and
667 SHOULD NOT be setuid.
669 Changes in 2.01:
670 * MEMDISK: Fix memory sizing bug when the ramdisk crosses the
671 16 MB boundary.
672 * MEMDISK: Add a "pause" option to stop immediately before
673 booting, to read off the messages.
674 * MEMDISK: Support disk images with DOSEMU headers.
675 * Update the mkdiskimage script to handle newer mtools
676 versions, and be able to generate disk images with DOSEMU
677 headers (controlled by the -d option).
678 * Fix the COM32 sample program.
679 * PXELINUX, ISOLINUX: Fix some COMBOOT API calls.
680 * PXELINUX: Doc fix.
681 * Build SYSLINUX into a small library for encapsulation into
682 other programs (however, please keep in mind this is a GPL'd
683 library.)
684 * SYSLINUX: Make installer work with "owner" in /etc/fstab.
685 * SYSLINUX: Fix issue with working on nonpartitioned hard disk
686 devices. THIS CONFIGURATION IS NOT RECOMMENDED.
688 Changes in 2.00:
689 * ALL: Add support for "COM32" (32-bit COMBOOT) images.
690 * ALL: Add an API for COMBOOT/COM32 images. See comboot.doc
691 for details. There is a C development environment for
692 COM32 being created; it should be ready at some point in
693 the future.
694 * Fix mbr.asm so that it actually works.
695 * SYSLINUX: The syslinux installer *SHOULD* now be safe to
696 run setuid root.
697 * PXELINUX: Fix bug where PXELINUX would override random
698 chunks of the UNDI code segment! Thanks to Kevin Tran for
699 finding this bug.
700 * ISOLINUX: Fix a bug related to slashes in pathnames.
701 * ISOLINUX: Fix a bug in handling initrds over 128 MB.
702 * ALL: Make the <Ctrl-V> key print out the version; this is
703 to help debugging.
704 * Add a small script, mkdiskimage, to create a DOS-formatted
705 hard disk image using mtools. This may be useful in
706 conjunction with MEMDISK.
707 * ISOLINUX: Search for a /boot/isolinux directory as well as
708 /isolinux.
709 * ALL: Fix a bug related to very long configuration files.
710 * PXELINUX: Work around a NASM bug which would result in no
711 delay before reset if an error occurs.
713 Changes in 1.76:
714 * ISOLINUX: Remove code no longer used which caused hangs on
715 some Toshiba laptops.
717 Changes in 1.75:
718 * ALL: NASM 0.98.32 or later is now required to build
719 SYSLINUX from sources.
720 * SYSLINUX: put back in the workaround for the BIOS floppy
721 table. This seems to be a requirement for "extended" floppy
722 formats to work correctly.
723 * SYSLINUX: No longer warn if one is trying to boot on a 286
724 or older. The above BIOS workaround no longer fits if the
725 requirement to use only 8086-compatible code in the early
726 boot is maintained. It made sense in 1994, but in 2002 a
727 286 or older is a museum object.
728 * SYSLINUX: Use a downright bizarre, stateful algorithm to try
729 to guess the maximum transfer size. I am *hoping* this will
730 cut down on the number of systems for which -s is required
731 to work at any acceptable speed.
732 * ISOLINUX: Add a few more workarounds for various broken El
733 Torito BIOSes.
734 * Make sure .depend files aren't accidentally packed...
735 * ALL: Fix bugs in the extension-detect code; this caused
736 files like COMBOOT images and CD boot sectors to be
737 mis-identified as Linux kernels and rejected.
738 * ALL: Fix the return from COMBOOT.
739 * ALL: Do some of the early groundwork for supporting DOS
740 system calls in COMBOOT.
741 * Get rid of unnecessary "near" directives, making the code
742 bigger.
743 * PXELINUX: Put the PXE stack back in the init state before
744 invoking a chain-loaded NBP.
745 * PXELINUX: Actually found the combination of calls that
746 allows some (most?) PXE 2+ stacks to be unloaded from memory
747 properly.
748 * PXELINUX: Add "keeppxe" command-line option to disable
749 the standard unloading of the PXE stack.
751 Changes in 1.74:
752 * SYSLINUX: fix bug that would cause valid kernel images to be
753 labelled "invalid".
755 Changes in 1.73:
756 * Work on removing gratuitous differences between modules.
757 * Break up the source in common and module-specific files.
758 * PXELINUX: Allow chaining of other PXE NBPs.
759 * ISOLINUX: Allow loading "CD-ROM boot sectors".
760 * ALL: generalize the definition of a boot sector/NBP.
762 Changes in 1.72:
763 * PXELINUX, ISOLINUX: Fix bugs in the new core code.
765 Changes in 1.71:
766 * Fix a "brown paper bag" class bug in the new core code.
768 Changes in 1.70:
769 * Major code restructuring.
770 * Relax the conventional memory limits somewhat.
771 * MEMDISK: Set up the "version number string" pointer in the
772 header correctly.
773 * SYSLINUX: Fix, again, "the bug that won't die": the use of
774 the offset parameter with the SYSLINUX installer.
775 * SYSLINUX: Fix possible superblock corruption problem in the
776 SYSLINUX installer.
778 Changes in 1.67:
779 * Handle bug in the location of initrd.
781 Changes in 1.66:
782 * MEMDISK: Make compile with newer versions of gcc.
784 Changes in 1.65:
785 * ISOLINUX: Support booting disk image files (to boot DOS or
786 other non-Linux operating systems), *IF* the BIOS works
787 correctly; unfortunately many BIOSes apparently don't.
788 * Support Linux boot protocol version 2.03 (explicitly
789 specify the initrd address limit.)
790 * Handle small "pseudo-kernels"; images that use the Linux
791 kernel boot protocols but are less than 64K in size.
792 * MEMDISK: New subsystem; this is a driver which allows
793 legacy OSes to boot using an in-memory simulated disk.
794 See memdisk/memdisk.doc for more info.
795 * PXELINUX, ISOLINUX: Correctly handle files larger than 65535
796 blocks (32 MB for PXELINUX, 128 MB for ISOLINUX.)
797 * PXELINUX: Make a best-effort attempt at freeing all memory
798 claimed. From the looks of it, it will fail on most PXE
799 stacks.
801 Changes in 1.64:
802 * Limited support for hardware flow control when using a
803 serial port console.
804 * Support specifying the serial port I/O address explicitly.
805 * Make DOS installer hopefully behave more nicely when used on
806 recent Windows versions.
807 * Fix returning to text mode when a font has been specified.
808 * Attempt to detect missing serial port hardware and disable
809 the serial port if there is nothing there.
811 Changes in 1.63:
812 * Make the ppmtolss16 program handle color conversion more
813 correctly.
814 * Clean up "make install" target, honour INSTALLROOT if it
815 exists.
816 * SYSLINUX: Fix stack-smash bug identified by Steffen
817 Winterfeldt.
818 * Hopefully fix return-to-text-mode on some graphics cards.
819 * ISOLINUX: Bug workaround for Award BIOS 4.51, and perhaps
820 other buggy BIOSes as well.
822 Changes in 1.62:
823 * PXELINUX: Allow the DHCP server to override the
824 configuration file name and pathname prefix, using
825 "site-specific" DHCP options.
826 * PXELINUX: Documentation fixes.
827 * PXELINUX: Fix the "ipappend" option; the last two values
828 were reversed vs. what the kernel expected.
829 * Introduce a way to return to text mode once we are already
830 in graphics mode. This may be useful for F-key help
831 screens.
832 * Fix several bugs in the way return to text mode was handled.
834 Changes in 1.61:
835 * ISOLINUX: Support full pathname searches. Max length for a
836 pathname is 255 characters. As a result, only 64 "label"
837 statements are supported in ISOLINUX.
838 * PXELINUX: Max filename length extended to 63 characters.
840 Changes in 1.60:
841 * Add support for graphical splash screens.
842 * Add mode control characters, which allows you to control
843 message display output depending on output mode (text,
844 graphics, or serial port.)
845 * ISOLINUX: New program, which boots Linux from a CD-ROM
846 without using floppy emulation mode. See isolinux.doc for
847 more details.
848 * PXELINUX: Don't search for boot sector file types, since
849 they don't work anyway.
850 * SYSLINUX: Document the LOCK command for Win9x, and the error
851 dialog box for WinNT/2K.
853 Changes in 1.54:
854 * PXELINUX: Fix code for finding !PXE from PXENV+. This was
855 due to a spec bug; match the most recent spec since that
856 seems to be what implementations actually do.
857 * SYSLINUX: Add some smarts to the boot sector, which
858 hopefully should reduce the number of systems which require
859 stupid mode ("syslinux -s").
860 * PXELINUX: Document further some of the pathologies with old
861 PXE stacks.
862 * When specifying a "default" command line, no longer
863 automatically appent "auto". See the "DEFAULT" command in
864 syslinux.doc for more information.
865 * PXELINUX: Clean up the allocation of local socket numbers.
867 Changes in 1.53:
868 * PXELINUX: Rename pxelinux.bin to pxelinux.0, to match what
869 most PXE servers seem to expect.
870 * PXELINUX: Update the DHCP/boot server setup documentation.
871 * PXELINUX: Support new "localboot" option for "label"
872 sections.
873 * PXELINUX: More robust parsing of DHCP/boot server packets.
874 * PXELINUX: Include a small utility program "gethostip" to
875 compute hexadecimal IP addresses.
877 Changes in 1.52:
878 * PXELINUX: Fix bugs introduced by new A20 code. (SYSLINUX
879 has also been changed for code consistency reasons, but I'm
880 pretty sure the changes are don't care on SYSLINUX.)
881 * Documentation updates.
882 * PXELINUX: Add "ipappend" option to generate an ip= option to
883 the kernel.
885 Changes in 1.51:
886 * PXELINUX: Not all PXE stacks fill in the IP address for a
887 type 3 cached info query. Use a type 2 cached info query
888 for this information (only.)
889 * Yet another attempt at A20 coding. Now support BIOS call
890 15:2401 as well, and handle machines which always have A20
891 on separately.
892 * Support memory detection using INT 15h, AX=0E820h. BIOS
893 manufacturers have apparently gotten sloppy about keeping
894 INT 15h, AX=0E801h working properly.
895 * Don't issue <CR><LF> onto the serial port when we're doing
896 screen wraparound.
898 Changes in 1.50:
899 * Yet another A20-code update. It seems some "legacy-free"
900 machines and embedded gear simply don't have a KBC to talk
901 to, and that waiting for one will wait forever. Sigh.
903 Changes in 1.49:
904 * SYSLINUX: Implement a hack for BIOS drivers which hog significant
905 chunks of low memory during boot. (Note: PXELINUX already
906 had this modification. SYSLINUX does still require that the
907 low 512K is available; PXELINUX requires 384K. Machines
908 with a physical memory hole in the low 640K cannot boot
909 Linux no matter what.) Depending what the reason is for the
910 memory hole, a new kernel (2.4.0-test3-pre3 or later) may be
911 required.
912 * SYSLINUX: Default installer binary now compiled against
913 glibc 2.1. If this is inappropriate for your system and you
914 still want to use the offical version of SYSLINUX, please
915 follow the instructions in "distrib.doc" to rebuild the
916 installer.
917 * SYSLINUX: Linux installer program now supports -o <offset>
918 option which does a loopback mount with the
919 -o loop,offset=<> option. Useful to run SYSLINUX on an
920 individual partition of a whole-harddisk image.
921 * Include the source code to a Master Boot Record (MBR)
922 functionally equivalent to the one installed DOS except it
923 includes EBIOS support, and should be resistant to geometry
924 changes. The MBR code is public domain.
925 * PXELINUX: Fix "double p" bug: if the tftp prefix was null,
926 all filenames would get a "p" preprended, e.g.
927 "ppxelinux.cfg" and "pvmlinux".
929 Changes in 1.48:
930 * PXELINUX: Workaround for PXE ROMs based on the Intel PXE PDK
931 3.0 build 071 and earlier: missing !PXE structure pointer.
932 * PXELINUX: Handle larger BOOTP/DHCP packages.
933 * PXELINUX: The command line passing was broken; fix.
934 * PXELINUX: Make COMBOOT images work.
935 * PXELINUX: Documentation on how to make booting work using
936 the PDK 3.0-derived clients, which aren't so generous as to
937 allow booting with only "PXEClient" specified.
939 Changes in 1.47:
940 * PXELINUX: RFC 1123 states that a TFTP implementation MUST
941 use adaptive timeout, "at least an exponential backoff of
942 retransmission timeout is necessary." Implement a very
943 simple exponential backoff for retransmits.
944 * PXELINUX: Updated documentation, including pointer to new
945 TFTP server.
946 * PXELINUX: When sending ERROR due to bad OACK, use the proper
947 destination port number (why are TFTP port numbers so odd?)
948 * PXELINUX: If the boot dies in the middle somewhere,
949 eventually give up and reset the machine (unattended
950 operation.)
952 Changes in 1.46:
953 * New program PXELINUX to do network booting using a
954 PXE-compliant (Pre-Execution Environment) network booting
955 PROM. See pxelinux.doc for details.
957 Changes in 1.45:
958 * Serial console support. See syslinux.doc for details.
960 Changes in 1.44:
961 * Change HIGHMEM_MAX to 38000000h to (hopefully) avoid the
962 kernel stepping on it; 3f000000h was apparently a higher
963 limit than the kernel used!
965 Changes in 1.43:
966 * Add sys2ansi.pl script to display the contents of a
967 colorized SYSLINUX file.
968 * Changed the io_delay once again, after a report that the
969 old delay port causes hangs on some systems.
971 Changes in 1.42:
972 * Frob the "fast A20 gate" port as well as the keyboard
973 controller; will this help systems with problems?
974 * Be even more paranoid about A20, unfortunately even this
975 seems to be not paranoid enough... what I don't understand
976 is that if there is hardware out there *this broken*, how
977 can it run Linux at all? Report an error message rather
978 than hang forever if A20 is stuck.
979 * Include some intermediate files in the distribution, plus
980 provide a "make installer" target for distributors to relink
981 the install programs only. I would prefer the syslinux boot
982 loader proper to be "binary clean" for debuggablity -- use
983 "make clean ; make installer" to rebuild the installers only.
985 Changes in 1.41:
986 * Don't get confused by directories, volume labels, or VFAT
987 long names.
988 * Use INT 15h, AX=0E801h to query memory size before trying
989 INT 15h, AH=88h. This not only provides more headroom
990 between the kernel and the initrd on large-memory machines,
991 but it appears some recent BIOSes actually have started
992 returning garbage for the AH=88h (older) call.
993 * Trust high memory beyond the 15 MB mark if the user has
994 specified it, or if obtained with INT 15h, AH=0E801h (with
995 no memory holes above 1 MB.)
997 Changes in 1.40:
998 * Increase A20M delay and put in a test to avoid problems on
999 certain IBM Thinkpads (thanks to Donnie Barnes of RedHat
1000 for vital info on this one.)
1001 * Support COMBOOT style boot command images.
1002 * Support chain loading (foreign operating systems, e.g. DOS).
1003 * Include a new "copybs" DOS utility to copy a boot sector to
1004 a file (under Linux, use "dd".)
1005 * Fix the DOS installer to work for disks over 32 MB.
1006 * SYSLINUX should now handle disks with more than 65536 tracks.
1008 Changes in 1.37:
1009 * Fix a bug that caused "label" statements in syslinux.cfg to
1010 not be handled properly.
1011 * Updated the documentation. Among other things, we now allow
1012 up to 128 "label" statements.
1014 Changes in 1.36:
1015 * Fix for booting old (pre-initrd) kernels.
1016 * It seems at least some versions of OS/2 doesn't set up all
1017 the fields in the superblock correctly. Account for that.
1018 * Fix bug that caused boot failure when using the mem= option.
1020 Changes in 1.35:
1021 * Loading from partitions now should work properly. (Actually
1022 tested, this time. You should even be able to dd a floppy
1023 to a partition and boot from it.)
1024 * Removed large workaround code for an alleged ancient BIOS
1025 bug I have never actually seen. The -s option should work
1026 on those machines, anyway.
1027 * Support for simple keyboard remappings, same as used by
1028 LILO (once again to support localization.) The program
1029 keytab-lilo.pl from the LILO distribution included to
1030 generate such maps.
1031 * Added a "safe, slow and stupid" (-s) option to the
1032 installers. This option will lobotomize the boot sector to
1033 hopefully work on even very buggy BIOSes.
1035 Changes in 1.34:
1036 * Ability to load a VGA font on bootup (for localized Linux
1037 distributions.)
1039 Changes in 1.33:
1040 * Bug fix in the Linux installer.
1041 * Added a workaround for a bug in certain AMI/Intel BIOSes
1042 when booting from CD-ROM.
1043 * Documentation changes.
1045 Changes in 1.32:
1046 * FAT16 filesystems are now supported.
1048 Changes in 1.31:
1049 * Now compiles under Linux, using NASM, rather than using
1050 Turbo Assembler under DOS. See http://www.cryogen.com/Nasm
1051 for information about NASM.
1052 * Linux-hosted SYSLINUX installer, as well as a
1053 rewritten DOS installer (now is written in assembler, so we
1054 don't need Turbo C.)
1056 Changes in 1.30:
1057 * Added support for loading bzImage and initrd loading, and made
1058 SYSLINUX new-setup-code aware (SYSLINUX 1.30 id=0x31).
1059 * Added LILO-style kernel labels; see the LABEL and IMPLICIT
1060 keywords in README file.
1061 * Added support for colorization of intro and help screens.
1062 * The vga= option is now handled correctly.
1063 * Massive rewrite of large chunks of the code in order to
1064 support the first two new features.
1066 Changes in 1.20:
1067 * Added simple online help at the "boot:" prompt.
1068 * Removed 2880K image as I no longer have access to such a
1069 floppy drive. (Donations accepted!!)
1070 * Decided to distribute the source in a subdirectory rather
1071 than in a nested zipfile.
1073 Changes in 1.11:
1074 * Removed a sanity check which would cause booting to fail on
1075 Phoenix BIOS version 4.03. Apparently this BIOS is buggy.
1077 Changes in 1.10:
1078 * Added configuration file SYSLINUX.CFG. This file contains all
1079 configurable options, and can be edited from any OS which can
1080 access an MS-DOS filesystem; there is no longer a need to run
1081 SYSLINUX.EXE except to write the boot sector.
1082 * Default command line now given by "default" line in config
1083 file.
1084 * LINUXMSG.TXT and BOOTMSG.TXT hard-coded file names replaced by
1085 "display" and "prompt" lines in config file.
1086 * LILO-style option appending now supported ("append" line in
1087 config file).
1088 * Prompt timeout is now supported ("timeout" line in config
1089 file). The timeout is cancelled when anything is typed on the
1090 command line.
1091 * Pressing <ESC> or <Ctrl-C> at the Loading... stage now aborts
1092 the kernel loading in progress and returns the user to the
1093 boot: prompt.
1094 * The installer now automatically sets the READONLY flag on
1095 LDLINUX.SYS.
1096 * Added 2880K disk image.
1098 Changes in 1.03:
1099 * Fixed bug that would prevent booting from double-density
1100 floppies and other DOS filesystems with multiple sectors per
1101 cluster.
1102 * Added 720K disk image.
1103 * Changed default kernel name on disk images to LINUX.
1105 Changes in 1.02:
1106 * Fixed bug that would garble the command line on recent kernels
1107 with more than 4 sectors of setup code (this wasn't really a
1108 *bug*; rather, a kernel change broke the code. Unfortunately
1109 the Linux boot interface is still sorely undocumented).
1110 * Added BOOTMSG.TXT file support (message file which does not
1111 force display of the boot prompt).
1113 Changes in 1.01:
1114 * Fixed bug on some (most?) 386 BIOSes would require two boot
1115 attempts.
