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. |
4 | |
5 | Changes in 3.11: |
6 | * MEMDISK: Fix bug by which accessing the real floppy disk |
7 | as B: in MS-DOS was broken. |
8 | * Simple menu system: allow tweaking of the screen layout. |
9 | * Simple menu system: better command-line editing, correctly |
10 | handle command lines above 256 characters. |
11 | * PXELINUX: revert memory allocation change that caused |
12 | problems on some network cards. |
13 | * MEMDISK: Try work around a bug on some BIOSes when no |
14 | physical floppy disk is present in the system. |
15 | * Enable the 16550A FIFOs, if present, when doing serial |
16 | console. |
17 | * New "totaltimeout" command establishes a timeout without |
18 | regard for any user input. |
19 | * Simple menu system: timeout behaviour now more in line with |
20 | user expectations. |
21 | |
22 | Changes in 3.10: |
23 | * gcc 4.0.1 compilation fixes. |
24 | * Add support for querying the PCI BIOS in libcom32 |
25 | (used by ethersel et al.) |
26 | * Fix PCI handing (ethersel etc) on several old chipsets (and |
27 | VMWare.) |
28 | * Try to deal with systems with broken EBIOS. |
29 | * New API call to do "localboot". |
30 | * New API call to query features. |
31 | * New API call to run kernel image, a lower-level call than |
32 | "run command". See comboot.doc. |
33 | * Fix for bug in EBIOS code discovered by Arwin Vosselman. |
34 | * NOESCAPE security fix. |
35 | * Comments are now recognized even without a space following #. |
36 | * Fix incorrect handling of mixes of entries with and without |
37 | MENU PASSWD. |
38 | * The idle API call now harmlessly returns failure if it is a |
39 | no-op. That way the caller can decide whether or not to |
40 | bother invoking it again. |
41 | * Temporarily disable the idle API call on PXELINUX, due to |
42 | some platforms on which the idle API call seems to hang; this |
43 | problem has not yet been debugged. |
44 | * MEMDISK: the handling of DOSEMU-headered images was broken; |
45 | fix it. |
46 | * EXTLINUX: symlinks are now supported. |
47 | * Simple menu system: N and P now work correctly as hotkeys. |
48 | * MEMDISK: more BIOS bug workarounds. |
49 | |
50 | Changes in 3.09: |
51 | * gcc4 compilation fix. |
52 | * <BEL> (Ctrl-G) in message files now causes a beep. |
53 | * Reduce the command line to 511 characters; 1023 caused |
54 | memory overflows. |
55 | |
56 | Changes in 3.08: |
57 | * SYSLINUX: Fix performance regression (-s mode always |
58 | enabled.) |
59 | * Add API function for idle loop. |
60 | * libutil: Add do_idle() function for idle loop, make |
61 | get_key() use it. |
62 | * libutil: Add SHA-1 and base64 functions. |
63 | * Simple menu system: add password support. |
64 | * EXTLINUX: Sparse files now handled correctly. |
65 | * EXTLINUX: Large directories now handled correctly. |
66 | * ALL: At the prompt, Ctrl-X now forces text mode. |
67 | * Fix configuration file parsing error, that could cause |
68 | hangs. |
69 | * Rewritten advanced menuing system from Murali Ganapathy. |
70 | * MEMDISK: New "bigraw" mode to work around certain broken |
71 | BIOS flash programs. |
72 | * COM32 module to boot Multiboot systems, including Xen. See |
73 | com32/modules/mboot.doc. |
74 | * Max command line changed to 1023 characters. Note that the |
75 | kernel proper still can only handle 255 characters without |
76 | patching, and COM16 binaries can only handle 125 characters. |
77 | |
78 | Changes in 3.07: |
79 | * Fix chainloading (chain.c32). |
80 | * Fix zlib build problem. |
81 | * Use a private copy of <linux/ext2_fs.h>. |
82 | |
83 | Changes in 3.06: |
84 | * Fix typo that caused the ramdisk to load in the wrong place. |
85 | |
86 | Changes in 3.05: |
87 | * New API function "shuffle and boot"; allows COM32 modules to |
88 | load or construct (almost) arbitrarily complex objects, |
89 | e.g. a kernel and its initrd/initramfs in pieces, and have |
90 | the API core reorganize memory for booting. (A library API |
91 | for this function will be introduced in a later version.) |
92 | * The initrd= option now supports multiple filenames separated |
93 | by commas. This is mostly useful for initramfs, which can |
94 | be composed of multiple separate cpio or cpio.gz archives. |
95 | (Note: all files except the last one are zero-padded to a 4K |
96 | page boundary. This should not affect initramfs.) |
97 | * EXTLINUX: Fix API function 000Ah (get derivative-specific |
98 | info). |
99 | * libcom32/ethersel: Support PCI Config Mechanism #2 on |
100 | machines still infested with that hideous old hack. |
101 | * SYSLINUX: Fix directory-parsing bug. |
102 | |
103 | Changes in 3.02: |
104 | * SYSLINUX: The "unix" installer now sets the MS-DOS |
105 | attributes (hidden, system, readonly.) |
106 | * COM32 library: build the .lnx (test modules for running |
107 | under Linux) as architecture native modules, in case |
108 | i386 devel libraries aren't installed. |
109 | * EXTLINUX: Hack for systems which don't have BLKGETSIZE64 |
110 | defined in the standard header files. |
111 | * Simple menu system: minor aestetic improvements, and try to |
112 | work better over a serial console (speed, and readability on |
113 | monochrome terminal emulators.) |
114 | * New CONSOLE directive to control output on the video console |
115 | (useful for dealing with some broken serial-forwarding |
116 | BIOSes.) |
117 | * New com32 module "ethersel" for searching for an Ethernet |
118 | card and selecting the proper version of Etherboot. |
119 | * EXTLINUX: Allow the user to override the detected geometry. |
120 | Add help. |
121 | |
122 | Changes in 3.01: |
123 | * EXTLINUX, SYSLINUX: Fix compile errors on some systems. |
124 | * EXTLINUX: Default to zipdrive geometry (64 heads, 32 |
125 | sectors) if no other geometry can be detected. |
126 | |
127 | Changes in 3.00: |
128 | * SYSLINUX: Support FAT32 and EDD. As an unfortunate |
129 | consequence, LDLINUX.SYS is no longer an ordinary file; it |
130 | is block-mapped at install time, which means it can only be |
131 | written using the syslinux installers. |
132 | * SYSLINUX: Reorganize the source code for the installers; |
133 | each one of the installers (dos, win32, unix, mtools) is now |
134 | built in its own subdirectory. In particular, "mtools" is |
135 | the unprivileged installer which uses mtools; "unix" is the |
136 | privileged installer which uses system calls. |
137 | * SYSLINUX: Completely rewritten DOS installer in C. |
138 | * ALL: "label" statement information is now stored in a |
139 | compressed format, which means that a lot more labels are |
140 | permitted (500-1000 in a typical configuration, but depends |
141 | on the complexity.) |
142 | * EXTLINUX: New derivative, which boots from an ext2/ext3 |
143 | filesystem. |
144 | * SYSLINUX: The DOS and Win32 installers can now optionally |
145 | write the boot sector to a file instead of the real boot |
146 | sector. This is not supported in the Linux installers, |
147 | however. |
148 | * ALL: New NOESCAPE command, disables the "hold down the Shift |
149 | key to display the prompt" behaviour. |
150 | * New simple menu system, as an alternative to the advanced |
151 | menu system already present. See README.menu for details. |
152 | * PXELINUX: Filenames can now be prefixed with an IP address |
153 | or DNS name plus :: (e.g. 192.0.2.1::filename or |
154 | server.domain.com::filename), which downloads a file from an |
155 | alternate TFTP server, or just a :: (e.g. ::filename), which |
156 | suppresses the common pathname prefix. See pxelinux.doc. |
157 | * SYSLINUX: Add an -m option to the DOS and Win32 installers |
158 | to write an MBR and -a to mark the partition SYSLINUX is |
159 | being installed on active. |
160 | * MEMDISK: Give a way to query the boot loader type while |
161 | running MEMDISK; see memdisk/memdisk.doc and |
162 | sample/mdiskchk.c. |
163 | * mkdiskimage: substantially improved mkdiskimage which, among |
164 | other things, can now be used to initialize USB keys as |
165 | zipdrives; see README.usbkey for more information. |
166 | |
167 | Changes in 2.13: |
168 | * MEMDISK: Fix command-line parsing "brown paper bag" class |
169 | bug. |
170 | * MEMDISK: Add "raw" mode to support the DOS boot disk from |
171 | WinME/XP, which seems to deliberately crash the system |
172 | when someone uses the "INT 15h mover" highmem API. |
173 | * Make "make install" do something sane for the com32 |
174 | development environment. |
175 | * In the spec file, create a separate -devel RPM for the com32 |
176 | development environment. |
177 | |
178 | Changes in 2.12: |
179 | * Simple C library, based on klibc, for writing COM32 |
180 | programs. |
181 | * Fix the handling of file length in loading of COM32 |
182 | programs. |
183 | * MEMDISK: Work around a linker bug by rearranging the code to |
184 | not use the linker for the 16-bit code. |
185 | * SYSLINUX: If we're building on a machine without a Win32 |
186 | (mingw) compiler, just skip building syslinux.exe. |
187 | * ISOLINUX: Support non-mkisofs mastering programs, at least |
188 | as long as the image is single-session. For best results, |
189 | ISOLINUX should be the only boot loader installed. |
190 | * MEMDISK: Allow the user to specify that the simulated disk |
191 | should be write-protected. |
192 | |
193 | Changes in 2.11: |
194 | * ALL: Add an API call to get the configuration file name. |
195 | * SYSLINUX: Fix bug in 2.10 that prevented it from working |
196 | correctly for a lot of people. |
197 | * SYSLINUX: In the installer, make mtools a bit less fussy. |
198 | * Make the menu system compile with newer gcc's. |
199 | |
200 | Changes in 2.10: |
201 | * MEMDISK: Handle images compressed with zip as well as with |
202 | gzip. Some Windows-based image tools apparently generate |
203 | these kinds of images by default. Patch by Patrick |
204 | LoPresti. |
205 | * Major menu improvement from Murali Ganapathy. |
206 | * ISOLINUX: Wonderfully sick and brilliant workaround for |
207 | severe bugs in certain Award BIOSes; from Knut Petersen. |
208 | * SYSLINUX: Fix for the nomtools installed, from Frederic |
209 | Pasteleurs. |
210 | * PXELINUX: Fix handling of IP numbers in the ranges |
211 | 100-109 and 200-209. |
212 | * ALL: New option "allowoptions" (defaults to 1), which |
213 | controls if options are allowed on the command line or not. |
214 | * SYSLINUX: Support building under klibc (see the klibc |
215 | distribution for details.) |
216 | |
217 | Changes in 2.09: |
218 | * SYSLINUX: Remove residual setuid crap from |
219 | syslinux-nomtools. |
220 | * Handle video pages correctly when using the API functions. |
221 | * Handle compiling on an x86-64 platform correctly. |
222 | * Menu system from Murali Krishnan Ganapathy; see the menu |
223 | directory for information. |
224 | * COMBOOT: Allow COMBOOT programs to change screen text mode. |
225 | * COMBOOT: Correct the documentation of how to detect |
226 | SYSLINUX from COMBOOT!!!! |
227 | * COMBOOT: Fix "get key without echo" API function. |
228 | * SYSLINUX: Fix bug that affected the API open function. |
229 | * ALL: Improve the E820 memory parser, to work around some |
230 | buggy BIOSes. |
231 | |
232 | Changes in 2.08: |
233 | * Add new configuration command "ontimeout" to allow timeout |
234 | to have a different action than just pressing Enter. |
235 | * Add new configuration command "onerror" to allow a custom |
236 | command to be executed in case the kernel image is not found. |
237 | * Fix bugs in the COMBOOT/COM32 command-line parsing. APPEND |
238 | now works with COMBOOT/COM32 images. |
239 | * PXELINUX: Poll for ARP requests while sitting at the |
240 | prompt. This makes some boot servers a lot less unhappy. |
241 | * PXELINUX: Actually free sockets when we get a failure |
242 | (including file not found.) This bug would cause us to run |
243 | out of sockets and thus "go deaf" after a while. |
244 | * MEMDISK: Add an API to query for the existence of MEMDISK. |
245 | * SYSLINUX: Fix loading boot sectors (.bs/.bss) from floppy |
246 | disk. |
247 | * .c32 is now one of the extensions searched for |
248 | automatically. |
249 | * PXELINUX: RFBG.exe seems to randomly overwrite memory |
250 | location 0x5700. Thus, don't use it! |
251 | * PXELINUX: Change pathname length max from 63 to 127; change |
252 | max vkernels from 128 to 64. |
253 | * Support Ctrl-U -> kill entire command line input. |
254 | * The "samples" directory contains a (barely at all tested) |
255 | chain loading example, chain.c32, which may be used to |
256 | chainload local floppy disks and hard disks. Use with |
257 | "chain fdN" or "chain hdN [partition]"; N = 0 for the first |
258 | drive of each type. |
259 | |
260 | Changes in 2.07: |
261 | * MEMDISK: Workaround for BIOSes which go into a snit when |
262 | they get a RESET command for the floppy system when there is |
263 | no floppy in the system. |
264 | * PXELINUX: Add "ipappend 2", which passes the hardware |
265 | address of the boot interface to the kernel as a |
266 | command-line option. |
267 | * mkdiskimage: fix the generation of the end limit. |
268 | * PXELINUX: Fix multiple bugs in chainloading of other NBPs. |
269 | * MEMDISK: Fix bug that would occationally cause "ran out of |
270 | input data" when using compressed disk images. |
271 | * SYSLINUX: Updates for the win32 installer (from Lars Munch.) |
272 | * PXELINUX: PXELINUX-specific options are now recognized both |
273 | in a vendor-option-space (a.k.a. type 43 encapsulated) as |
274 | well as in a site-option-space (unencapsulated.) |
275 | * COM32: Don't crash when DS != 0. |
276 | * COMBOOT/COM32: Make file reading work correctly. Thanks to |
277 | Phung Chi Kien for submitting a test program. |
278 | |
279 | Changes in 2.06: |
280 | * ALL: Fix problem that would occationally cause a |
281 | boot failure, depending on the length of the kernel. |
282 | * ISOLINUX: Fix problem that would occationally cause a |
283 | boot failure, depending on the length of directories. |
284 | * SYSLINUX: Win32 installer now flushes buffers. |
285 | * ppmtolss16: Be fully compliant with the PNM spec; |
286 | actually process comments in the header and odd |
287 | alignments of the various parameters, as well as |
288 | "plain" (not raw) files and PBM and PGM files. |
289 | * PXELINUX: Lower the default MTU to 1472 in order to deal |
290 | with systems with slightly nonstandard MTUs, and PXE |
291 | stacks which don't defragment correctly. Unfortunately this |
292 | is very hard to test dynamically. |
293 | |
294 | Changes in 2.05: |
295 | * PXELINUX: Add a default query based on the hardware address |
296 | of the boot device. This is in lower case hexadecimal form |
297 | separated by dashes and including the hardware type, for |
298 | example, the Ethernet (type 1) address 88:99:AA:BB:CC:DD |
299 | would query the file pxelinux.cfg/01-88-99-aa-bb-cc-dd. |
300 | * PXELINUX: Fix bug involving non-IP-based config file names. |
301 | * SYSLINUX: New installer for WinNT-based systems, from Lars |
302 | Munch. |
303 | * MEMDISK: Fix handling of memory region overlap when |
304 | decompressing. Thanks to Mikhail Kupchik for identifying |
305 | the problem. |
306 | |
307 | Changes in 2.04: |
308 | * ALL: Reclaim even more low memory by observing that |
309 | comboot_seg == real_mode_seg is perfectly fine, and by the |
310 | fact that the 1000h segment managed to get unused in all |
311 | derivatives... |
312 | * PXELINUX: Attempt to negotiate full Ethernet-sized blocks |
313 | (1468 bytes) using the blksize option. |
314 | * SYSLINUX: Resurrect the old no-mtools version of the |
315 | installer, although as a root-only tool. Some distributors |
316 | have indicated that they need a small standalone installer. |
317 | * MEMDISK: Fix a memory offset computation error when |
318 | installing compressed disks which generally would cause |
319 | 1 MB of memory to be wasted. |
320 | * MEMDISK: Fix installing the E820 memory map. Calling |
321 | INT 15h AX=0E820h with MEMDISK 2.03 loaded would give a |
322 | completely corrupt memory map. |
323 | * SYSLINUX: Make libsyslinux a dynamic library, so that it can |
324 | be updated separately from client programs. The whole idea, |
325 | after all, is to enable alternate programs to become |
326 | syslinux installers. |
327 | * Include an rpm spec file in the distribution, so rpmbuild |
328 | -ta works. |
329 | |
330 | Changes in 2.03: |
331 | * Actually support comment lines in the configuration file. |
332 | * PXELINUX: Try to resolve some problems with stack switches. |
333 | * PXELINUX: Handle PXE stacks with broken routing. |
334 | With these workarounds, the remote install PXE boot floppy |
335 | (rbfg.exe) from Argon Technologies should work correctly. |
336 | * Fix problems with Perl scripts in UTF-8 locales. |
337 | * You probably need NASM 0.98.34 or later to compile this |
338 | version. 0.98.36 is recommended. |
339 | * MEMDISK: Now supports gzip compressed images. |
340 | |
341 | Changes in 2.02: |
342 | * SYSLINUX: Security flaws have been found in the SYSLINUX |
343 | installer when running setuid root. Rewrite the SYSLINUX |
344 | installer so it uses mtools instead. It therefore now |
345 | requires mtools (specifically mcopy and mattrib) to exist on |
346 | your system, but it will not require root privileges and |
347 | SHOULD NOT be setuid. |
348 | |
349 | Changes in 2.01: |
350 | * MEMDISK: Fix memory sizing bug when the ramdisk crosses the |
351 | 16 MB boundary. |
352 | * MEMDISK: Add a "pause" option to stop immediately before |
353 | booting, to read off the messages. |
354 | * MEMDISK: Support disk images with DOSEMU headers. |
355 | * Update the mkdiskimage script to handle newer mtools |
356 | versions, and be able to generate disk images with DOSEMU |
357 | headers (controlled by the -d option). |
358 | * Fix the COM32 sample program. |
359 | * PXELINUX, ISOLINUX: Fix some COMBOOT API calls. |
360 | * PXELINUX: Doc fix. |
361 | * Build SYSLINUX into a small library for encapsulation into |
362 | other programs (however, please keep in mind this is a GPL'd |
363 | library.) |
364 | * SYSLINUX: Make installer work with "owner" in /etc/fstab. |
365 | * SYSLINUX: Fix issue with working on nonpartitioned hard disk |
366 | devices. THIS CONFIGURATION IS NOT RECOMMENDED. |
367 | |
368 | Changes in 2.00: |
369 | * ALL: Add support for "COM32" (32-bit COMBOOT) images. |
370 | * ALL: Add an API for COMBOOT/COM32 images. See comboot.doc |
371 | for details. There is a C development environment for |
372 | COM32 being created; it should be ready at some point in |
373 | the future. |
374 | * Fix mbr.asm so that it actually works. |
375 | * SYSLINUX: The syslinux installer *SHOULD* now be safe to |
376 | run setuid root. |
377 | * PXELINUX: Fix bug where PXELINUX would override random |
378 | chunks of the UNDI code segment! Thanks to Kevin Tran for |
379 | finding this bug. |
380 | * ISOLINUX: Fix a bug related to slashes in pathnames. |
381 | * ISOLINUX: Fix a bug in handling initrds over 128 MB. |
382 | * ALL: Make the <Ctrl-V> key print out the version; this is |
383 | to help debugging. |
384 | * Add a small script, mkdiskimage, to create a DOS-formatted |
385 | hard disk image using mtools. This may be useful in |
386 | conjunction with MEMDISK. |
387 | * ISOLINUX: Search for a /boot/isolinux directory as well as |
388 | /isolinux. |
389 | * ALL: Fix a bug related to very long configuration files. |
390 | * PXELINUX: Work around a NASM bug which would result in no |
391 | delay before reset if an error occurs. |
392 | |
393 | Changes in 1.76: |
394 | * ISOLINUX: Remove code no longer used which caused hangs on |
395 | some Toshiba laptops. |
396 | |
397 | Changes in 1.75: |
398 | * ALL: NASM 0.98.32 or later is now required to build |
399 | SYSLINUX from sources. |
400 | * SYSLINUX: put back in the workaround for the BIOS floppy |
401 | table. This seems to be a requirement for "extended" floppy |
402 | formats to work correctly. |
403 | * SYSLINUX: No longer warn if one is trying to boot on a 286 |
404 | or older. The above BIOS workaround no longer fits if the |
405 | requirement to use only 8086-compatible code in the early |
406 | boot is maintained. It made sense in 1994, but in 2002 a |
407 | 286 or older is a museum object. |
408 | * SYSLINUX: Use a downright bizarre, stateful algorithm to try |
409 | to guess the maximum transfer size. I am *hoping* this will |
410 | cut down on the number of systems for which -s is required |
411 | to work at any acceptable speed. |
412 | * ISOLINUX: Add a few more workarounds for various broken El |
413 | Torito BIOSes. |
414 | * Make sure .depend files aren't accidentally packed... |
415 | * ALL: Fix bugs in the extension-detect code; this caused |
416 | files like COMBOOT images and CD boot sectors to be |
417 | mis-identified as Linux kernels and rejected. |
418 | * ALL: Fix the return from COMBOOT. |
419 | * ALL: Do some of the early groundwork for supporting DOS |
420 | system calls in COMBOOT. |
421 | * Get rid of unnecessary "near" directives, making the code |
422 | bigger. |
423 | * PXELINUX: Put the PXE stack back in the init state before |
424 | invoking a chain-loaded NBP. |
425 | * PXELINUX: Actually found the combination of calls that |
426 | allows some (most?) PXE 2+ stacks to be unloaded from memory |
427 | properly. |
428 | * PXELINUX: Add "keeppxe" command-line option to disable |
429 | the standard unloading of the PXE stack. |
430 | |
431 | Changes in 1.74: |
432 | * SYSLINUX: fix bug that would cause valid kernel images to be |
433 | labelled "invalid". |
434 | |
435 | Changes in 1.73: |
436 | * Work on removing gratuitous differences between modules. |
437 | * Break up the source in common and module-specific files. |
438 | * PXELINUX: Allow chaining of other PXE NBPs. |
439 | * ISOLINUX: Allow loading "CD-ROM boot sectors". |
440 | * ALL: generalize the definition of a boot sector/NBP. |
441 | |
442 | Changes in 1.72: |
443 | * PXELINUX, ISOLINUX: Fix bugs in the new core code. |
444 | |
445 | Changes in 1.71: |
446 | * Fix a "brown paper bag" class bug in the new core code. |
447 | |
448 | Changes in 1.70: |
449 | * Major code restructuring. |
450 | * Relax the conventional memory limits somewhat. |
451 | * MEMDISK: Set up the "version number string" pointer in the |
452 | header correctly. |
453 | * SYSLINUX: Fix, again, "the bug that won't die": the use of |
454 | the offset parameter with the SYSLINUX installer. |
455 | * SYSLINUX: Fix possible superblock corruption problem in the |
456 | SYSLINUX installer. |
457 | |
458 | Changes in 1.67: |
459 | * Handle bug in the location of initrd. |
460 | |
461 | Changes in 1.66: |
462 | * MEMDISK: Make compile with newer versions of gcc. |
463 | |
464 | Changes in 1.65: |
465 | * ISOLINUX: Support booting disk image files (to boot DOS or |
466 | other non-Linux operating systems), *IF* the BIOS works |
467 | correctly; unfortunately many BIOSes apparently don't. |
468 | * Support Linux boot protocol version 2.03 (explicitly |
469 | specify the initrd address limit.) |
470 | * Handle small "pseudo-kernels"; images that use the Linux |
471 | kernel boot protocols but are less than 64K in size. |
472 | * MEMDISK: New subsystem; this is a driver which allows |
473 | legacy OSes to boot using an in-memory simulated disk. |
474 | See memdisk/memdisk.doc for more info. |
475 | * PXELINUX, ISOLINUX: Correctly handle files larger than 65535 |
476 | blocks (32 MB for PXELINUX, 128 MB for ISOLINUX.) |
477 | * PXELINUX: Make a best-effort attempt at freeing all memory |
478 | claimed. From the looks of it, it will fail on most PXE |
479 | stacks. |
480 | |
481 | Changes in 1.64: |
482 | * Limited support for hardware flow control when using a |
483 | serial port console. |
484 | * Support specifying the serial port I/O address explicitly. |
485 | * Make DOS installer hopefully behave more nicely when used on |
486 | recent Windows versions. |
487 | * Fix returning to text mode when a font has been specified. |
488 | * Attempt to detect missing serial port hardware and disable |
489 | the serial port if there is nothing there. |
490 | |
491 | Changes in 1.63: |
492 | * Make the ppmtolss16 program handle color conversion more |
493 | correctly. |
494 | * Clean up "make install" target, honour INSTALLROOT if it |
495 | exists. |
496 | * SYSLINUX: Fix stack-smash bug identified by Steffen |
497 | Winterfeldt. |
498 | * Hopefully fix return-to-text-mode on some graphics cards. |
499 | * ISOLINUX: Bug workaround for Award BIOS 4.51, and perhaps |
500 | other buggy BIOSes as well. |
501 | |
502 | Changes in 1.62: |
503 | * PXELINUX: Allow the DHCP server to override the |
504 | configuration file name and pathname prefix, using |
505 | "site-specific" DHCP options. |
506 | * PXELINUX: Documentation fixes. |
507 | * PXELINUX: Fix the "ipappend" option; the last two values |
508 | were reversed vs. what the kernel expected. |
509 | * Introduce a way to return to text mode once we are already |
510 | in graphics mode. This may be useful for F-key help |
511 | screens. |
512 | * Fix several bugs in the way return to text mode was handled. |
513 | |
514 | Changes in 1.61: |
515 | * ISOLINUX: Support full pathname searches. Max length for a |
516 | pathname is 255 characters. As a result, only 64 "label" |
517 | statements are supported in ISOLINUX. |
518 | * PXELINUX: Max filename length extended to 63 characters. |
519 | |
520 | Changes in 1.60: |
521 | * Add support for graphical splash screens. |
522 | * Add mode control characters, which allows you to control |
523 | message display output depending on output mode (text, |
524 | graphics, or serial port.) |
525 | * ISOLINUX: New program, which boots Linux from a CD-ROM |
526 | without using floppy emulation mode. See isolinux.doc for |
527 | more details. |
528 | * PXELINUX: Don't search for boot sector file types, since |
529 | they don't work anyway. |
530 | * SYSLINUX: Document the LOCK command for Win9x, and the error |
531 | dialog box for WinNT/2K. |
532 | |
533 | Changes in 1.54: |
534 | * PXELINUX: Fix code for finding !PXE from PXENV+. This was |
535 | due to a spec bug; match the most recent spec since that |
536 | seems to be what implementations actually do. |
537 | * SYSLINUX: Add some smarts to the boot sector, which |
538 | hopefully should reduce the number of systems which require |
539 | stupid mode ("syslinux -s"). |
540 | * PXELINUX: Document further some of the pathologies with old |
541 | PXE stacks. |
542 | * When specifying a "default" command line, no longer |
543 | automatically appent "auto". See the "DEFAULT" command in |
544 | syslinux.doc for more information. |
545 | * PXELINUX: Clean up the allocation of local socket numbers. |
546 | |
547 | Changes in 1.53: |
548 | * PXELINUX: Rename pxelinux.bin to pxelinux.0, to match what |
549 | most PXE servers seem to expect. |
550 | * PXELINUX: Update the DHCP/boot server setup documentation. |
551 | * PXELINUX: Support new "localboot" option for "label" |
552 | sections. |
553 | * PXELINUX: More robust parsing of DHCP/boot server packets. |
554 | * PXELINUX: Include a small utility program "gethostip" to |
555 | compute hexadecimal IP addresses. |
556 | |
557 | Changes in 1.52: |
558 | * PXELINUX: Fix bugs introduced by new A20 code. (SYSLINUX |
559 | has also been changed for code consistency reasons, but I'm |
560 | pretty sure the changes are don't care on SYSLINUX.) |
561 | * Documentation updates. |
562 | * PXELINUX: Add "ipappend" option to generate an ip= option to |
563 | the kernel. |
564 | |
565 | Changes in 1.51: |
566 | * PXELINUX: Not all PXE stacks fill in the IP address for a |
567 | type 3 cached info query. Use a type 2 cached info query |
568 | for this information (only.) |
569 | * Yet another attempt at A20 coding. Now support BIOS call |
570 | 15:2401 as well, and handle machines which always have A20 |
571 | on separately. |
572 | * Support memory detection using INT 15h, AX=0E820h. BIOS |
573 | manufacturers have apparently gotten sloppy about keeping |
574 | INT 15h, AX=0E801h working properly. |
575 | * Don't issue <CR><LF> onto the serial port when we're doing |
576 | screen wraparound. |
577 | |
578 | Changes in 1.50: |
579 | * Yet another A20-code update. It seems some "legacy-free" |
580 | machines and embedded gear simply don't have a KBC to talk |
581 | to, and that waiting for one will wait forever. Sigh. |
582 | |
583 | Changes in 1.49: |
584 | * SYSLINUX: Implement a hack for BIOS drivers which hog significant |
585 | chunks of low memory during boot. (Note: PXELINUX already |
586 | had this modification. SYSLINUX does still require that the |
587 | low 512K is available; PXELINUX requires 384K. Machines |
588 | with a physical memory hole in the low 640K cannot boot |
589 | Linux no matter what.) Depending what the reason is for the |
590 | memory hole, a new kernel (2.4.0-test3-pre3 or later) may be |
591 | required. |
592 | * SYSLINUX: Default installer binary now compiled against |
593 | glibc 2.1. If this is inappropriate for your system and you |
594 | still want to use the offical version of SYSLINUX, please |
595 | follow the instructions in "distrib.doc" to rebuild the |
596 | installer. |
597 | * SYSLINUX: Linux installer program now supports -o <offset> |
598 | option which does a loopback mount with the |
599 | -o loop,offset=<> option. Useful to run SYSLINUX on an |
600 | individual partition of a whole-harddisk image. |
601 | * Include the source code to a Master Boot Record (MBR) |
602 | functionally equivalent to the one installed DOS except it |
603 | includes EBIOS support, and should be resistant to geometry |
604 | changes. The MBR code is public domain. |
605 | * PXELINUX: Fix "double p" bug: if the tftp prefix was null, |
606 | all filenames would get a "p" preprended, e.g. |
607 | "ppxelinux.cfg" and "pvmlinux". |
608 | |
609 | Changes in 1.48: |
610 | * PXELINUX: Workaround for PXE ROMs based on the Intel PXE PDK |
611 | 3.0 build 071 and earlier: missing !PXE structure pointer. |
612 | * PXELINUX: Handle larger BOOTP/DHCP packages. |
613 | * PXELINUX: The command line passing was broken; fix. |
614 | * PXELINUX: Make COMBOOT images work. |
615 | * PXELINUX: Documentation on how to make booting work using |
616 | the PDK 3.0-derived clients, which aren't so generous as to |
617 | allow booting with only "PXEClient" specified. |
618 | |
619 | Changes in 1.47: |
620 | * PXELINUX: RFC 1123 states that a TFTP implementation MUST |
621 | use adaptive timeout, "at least an exponential backoff of |
622 | retransmission timeout is necessary." Implement a very |
623 | simple exponential backoff for retransmits. |
624 | * PXELINUX: Updated documentation, including pointer to new |
625 | TFTP server. |
626 | * PXELINUX: When sending ERROR due to bad OACK, use the proper |
627 | destination port number (why are TFTP port numbers so odd?) |
628 | * PXELINUX: If the boot dies in the middle somewhere, |
629 | eventually give up and reset the machine (unattended |
630 | operation.) |
631 | |
632 | Changes in 1.46: |
633 | * New program PXELINUX to do network booting using a |
634 | PXE-compliant (Pre-Execution Environment) network booting |
635 | PROM. See pxelinux.doc for details. |
636 | |
637 | Changes in 1.45: |
638 | * Serial console support. See syslinux.doc for details. |
639 | |
640 | Changes in 1.44: |
641 | * Change HIGHMEM_MAX to 38000000h to (hopefully) avoid the |
642 | kernel stepping on it; 3f000000h was apparently a higher |
643 | limit than the kernel used! |
644 | |
645 | Changes in 1.43: |
646 | * Add sys2ansi.pl script to display the contents of a |
647 | colorized SYSLINUX file. |
648 | * Changed the io_delay once again, after a report that the |
649 | old delay port causes hangs on some systems. |
650 | |
651 | Changes in 1.42: |
652 | * Frob the "fast A20 gate" port as well as the keyboard |
653 | controller; will this help systems with problems? |
654 | * Be even more paranoid about A20, unfortunately even this |
655 | seems to be not paranoid enough... what I don't understand |
656 | is that if there is hardware out there *this broken*, how |
657 | can it run Linux at all? Report an error message rather |
658 | than hang forever if A20 is stuck. |
659 | * Include some intermediate files in the distribution, plus |
660 | provide a "make installer" target for distributors to relink |
661 | the install programs only. I would prefer the syslinux boot |
662 | loader proper to be "binary clean" for debuggablity -- use |
663 | "make clean ; make installer" to rebuild the installers only. |
664 | |
665 | Changes in 1.41: |
666 | * Don't get confused by directories, volume labels, or VFAT |
667 | long names. |
668 | * Use INT 15h, AX=0E801h to query memory size before trying |
669 | INT 15h, AH=88h. This not only provides more headroom |
670 | between the kernel and the initrd on large-memory machines, |
671 | but it appears some recent BIOSes actually have started |
672 | returning garbage for the AH=88h (older) call. |
673 | * Trust high memory beyond the 15 MB mark if the user has |
674 | specified it, or if obtained with INT 15h, AH=0E801h (with |
675 | no memory holes above 1 MB.) |
676 | |
677 | Changes in 1.40: |
678 | * Increase A20M delay and put in a test to avoid problems on |
679 | certain IBM Thinkpads (thanks to Donnie Barnes of RedHat |
680 | for vital info on this one.) |
681 | * Support COMBOOT style boot command images. |
682 | * Support chain loading (foreign operating systems, e.g. DOS). |
683 | * Include a new "copybs" DOS utility to copy a boot sector to |
684 | a file (under Linux, use "dd".) |
685 | * Fix the DOS installer to work for disks over 32 MB. |
686 | * SYSLINUX should now handle disks with more than 65536 tracks. |
687 | |
688 | Changes in 1.37: |
689 | * Fix a bug that caused "label" statements in syslinux.cfg to |
690 | not be handled properly. |
691 | * Updated the documentation. Among other things, we now allow |
692 | up to 128 "label" statements. |
693 | |
694 | Changes in 1.36: |
695 | * Fix for booting old (pre-initrd) kernels. |
696 | * It seems at least some versions of OS/2 doesn't set up all |
697 | the fields in the superblock correctly. Account for that. |
698 | * Fix bug that caused boot failure when using the mem= option. |
699 | |
700 | Changes in 1.35: |
701 | * Loading from partitions now should work properly. (Actually |
702 | tested, this time. You should even be able to dd a floppy |
703 | to a partition and boot from it.) |
704 | * Removed large workaround code for an alleged ancient BIOS |
705 | bug I have never actually seen. The -s option should work |
706 | on those machines, anyway. |
707 | * Support for simple keyboard remappings, same as used by |
708 | LILO (once again to support localization.) The program |
709 | keytab-lilo.pl from the LILO distribution included to |
710 | generate such maps. |
711 | * Added a "safe, slow and stupid" (-s) option to the |
712 | installers. This option will lobotomize the boot sector to |
713 | hopefully work on even very buggy BIOSes. |
714 | |
715 | Changes in 1.34: |
716 | * Ability to load a VGA font on bootup (for localized Linux |
717 | distributions.) |
718 | |
719 | Changes in 1.33: |
720 | * Bug fix in the Linux installer. |
721 | * Added a workaround for a bug in certain AMI/Intel BIOSes |
722 | when booting from CD-ROM. |
723 | * Documentation changes. |
724 | |
725 | Changes in 1.32: |
726 | * FAT16 filesystems are now supported. |
727 | |
728 | Changes in 1.31: |
729 | * Now compiles under Linux, using NASM, rather than using |
730 | Turbo Assembler under DOS. See http://www.cryogen.com/Nasm |
731 | for information about NASM. |
732 | * Linux-hosted SYSLINUX installer, as well as a |
733 | rewritten DOS installer (now is written in assembler, so we |
734 | don't need Turbo C.) |
735 | |
736 | Changes in 1.30: |
737 | * Added support for loading bzImage and initrd loading, and made |
738 | SYSLINUX new-setup-code aware (SYSLINUX 1.30 id=0x31). |
739 | * Added LILO-style kernel labels; see the LABEL and IMPLICIT |
740 | keywords in README file. |
741 | * Added support for colorization of intro and help screens. |
742 | * The vga= option is now handled correctly. |
743 | * Massive rewrite of large chunks of the code in order to |
744 | support the first two new features. |
745 | |
746 | Changes in 1.20: |
747 | * Added simple online help at the "boot:" prompt. |
748 | * Removed 2880K image as I no longer have access to such a |
749 | floppy drive. (Donations accepted!!) |
750 | * Decided to distribute the source in a subdirectory rather |
751 | than in a nested zipfile. |
752 | |
753 | Changes in 1.11: |
754 | * Removed a sanity check which would cause booting to fail on |
755 | Phoenix BIOS version 4.03. Apparently this BIOS is buggy. |
756 | |
757 | Changes in 1.10: |
758 | * Added configuration file SYSLINUX.CFG. This file contains all |
759 | configurable options, and can be edited from any OS which can |
760 | access an MS-DOS filesystem; there is no longer a need to run |
761 | SYSLINUX.EXE except to write the boot sector. |
762 | * Default command line now given by "default" line in config |
763 | file. |
764 | * LINUXMSG.TXT and BOOTMSG.TXT hard-coded file names replaced by |
765 | "display" and "prompt" lines in config file. |
766 | * LILO-style option appending now supported ("append" line in |
767 | config file). |
768 | * Prompt timeout is now supported ("timeout" line in config |
769 | file). The timeout is cancelled when anything is typed on the |
770 | command line. |
771 | * Pressing <ESC> or <Ctrl-C> at the Loading... stage now aborts |
772 | the kernel loading in progress and returns the user to the |
773 | boot: prompt. |
774 | * The installer now automatically sets the READONLY flag on |
775 | LDLINUX.SYS. |
776 | * Added 2880K disk image. |
777 | |
778 | Changes in 1.03: |
779 | * Fixed bug that would prevent booting from double-density |
780 | floppies and other DOS filesystems with multiple sectors per |
781 | cluster. |
782 | * Added 720K disk image. |
783 | * Changed default kernel name on disk images to LINUX. |
784 | |
785 | Changes in 1.02: |
786 | * Fixed bug that would garble the command line on recent kernels |
787 | with more than 4 sectors of setup code (this wasn't really a |
788 | *bug*; rather, a kernel change broke the code. Unfortunately |
789 | the Linux boot interface is still sorely undocumented). |
790 | * Added BOOTMSG.TXT file support (message file which does not |
791 | force display of the boot prompt). |
792 | |
793 | Changes in 1.01: |
794 | * Fixed bug on some (most?) 386 BIOSes would require two boot |
795 | attempts. |
