2006-03-09 version 0.4.2pre2
The directory `boot/grub/' was removed from the release tree(GRUB4DOS
does not use the stage files at boot time). The default config file for
GRUB.EXE was changed to (hd0,0)/menu.lst(but preset_menu still locates
(hd0,0)/boot/grub/menu.lst when (hd0,0)/menu.lst does not exist).
Added DOS command-line options --bypass, --time-out=T and --hot-key=K
for GRUB.EXE.
2006-02-24 version 0.4.2pre1
gcc-4 support by VirusCamp.
Limited support for returning to DOS from GRUB.EXE.
Implemented a new feature that GRUB.EXE can be used as a DOS device
driver and be started in CONFIG.SYS with a DEVICE line.
Better IODELAY was made for initialization of PIC to fix the
keyboard-not-responding problem when running through KEXEC.
Better A20 gate control was made to help fix various problems on the
boot of grub.
2005-12-14 version 0.4.1
Fixed a partition enumeration bug(in disk_io.c). Fixed a bug of mapping
partitions to harddrives(in builtins.c). Fixed a bug that causes
failure when `find --set-root' on a CD-ROM device(in builtins.c). Added
a new feature of directly chainloading ntldr and some dos kernels.
2005-11-14 version 0.4.1pre32
Fixed more bugs.
2005-11-02 version 0.4.1pre31
A few bugs were fixed.
2005-10-23 version 0.4.1pre30
A bug about "bootlace.com --floppy" was fixed.
2005-10-18 version 0.4.1pre29
Added ram disk device (rd) to access, typically, the initrd image.
Added many new command-line options for bootlace.com to install GRLDR
boot record onto the boot sector of a floppy. A few bugs about
"map --mem" were fixed. Another bug about finding grldr in NTFS was
also fixed. It may cause the machine to hang up when there is no ntfs
boot record in the boot area of the NTFS partition.
2005-09-25 version 0.4.1pre28
Commandline option --config-file="FILENAME_OR_RAW_COMMANDS" was added
for GRUB.EXE where GRUB.EXE is treated as a Linux kernel.
Fixed a bug which causes installation failure when BOOTLACE.COM is
used for large disks.
2005-09-21 version 0.4.1pre27
Added a patch to the kexec-tools-1.101. Kexec might fail to load
grub.exe without this patch.
2005-09-14 version 0.4.1pre26
Fixed a bug for the DOS part of BOOTLACE.COM
2005-09-11 version 0.4.1pre25

--read-only was added for BOOTLACE.COM; A few bug fixes.
2005-09-01 version 0.4.1pre24
BOOTLACE.COM runs under both DOS and Linux.
2005-08-27 version 0.4.1pre23
Added a utility BOOTLACE.COM for installing grldr bootstrap code to MBR
2005-07-30 version 0.4.1pre22
Added bootstrap file GRLDR.MBR for launching grldr from MBR.
2005-07-24 version 0.4.1pre21
Added Windows NT 4.0 support(actually fixed a bug reported by Stefan
Baur). For other new features, see README.txt.
2005-07-20 version 0.4.1pre20
Added ext2/ext3 boot record code for loading grldr from the beginning
sector of a floppy or a partition.
2005-05-25 version 0.4.1pre5
GRUB commands can be embedded into the command line of GRUB.EXE
2005-05-20 version 0.4.1pre4
Bug fixes: When the system has no floppies, some operations,
e.g., the find command, will hang the machine.
2005-05-17 version 0.4.1pre3
Search for cdrom_drive from drive 0x88 to drive 0xff
2005-05-11 version 0.4.1pre2
Our base is now upgraded to GNU GRUB 0.97.
2005-04-25 version 0.4.1pre
Fixed a bug reported by Gilles van Ruymbeke
<gvr_no_spam_123@ruymbeke.com> <gvr_grub4dos123@ruymbeke.ch>:
The map_func improperly opened the emulation image for 3 times, that
might slow down the load speed heavily, especially for gzipped files.
2005-04-15 version 0.4.0
Add /boot/grub/menu.lst in preset menu. This is final.
2005-04-07 version 0.4.0pre7
config_file takes precedence over preset_menu.
2005-04-06 version 0.4.0pre6
GRLDR can be used with no-emulation-mode bootable CD-ROM.
2005-03-09 version 0.4.0pre4
Now preset menu find /menu.lst, no longer support /boot/grub/menu.lst
Partition images can emulate a partition (hd?,0) with --mem option.
2005-03-02 version 0.4.0pre3
GRLDR startup code search all partitions in all harddrives for GRLDR.
chainloader can boot images larger than 512 bytes, and can load image
to a different location than 0000:7C00.
2005-02-06 version 0.4.0pre
Switched to GNU GRUB 0.96
The --mem option of MAP command was added for memdrive emulation.
Also announced 0.2.0 final.
2004-10-23 version 0.2.0pre13

GRUB4LIN is introduced to boot off LINUX.
Fixed a bug reported by windrv: NTFS check contiguity failure
Rearranged the patches.
2004-08-31 version 0.2.0pre12
Fixed a bug reported by szwp: cannot load GRLDR on partition that is
not CHS-accessible.
Fixed a bug reported by windrv: take too much time to check contiguity

Patches from Gandalf: NTFS and ATAPI CDROM support(also thanks to
Tobias Svensson <tobiassvensson@home.se>)
Patches from Chris Semler <csemler@mail.com>: findroot
2004-04-12 version 0.2.0pre6
Now GRUB.EXE can be used in CONFIG.SYS this way:
shell=C:\some\where\grub.exe --config-file=(hd0,0)/boot/grub/menu.lst
or
shell=C:\some\where\grub.exe
No other changes.
2004-04-09 version 0.2.0pre5
Now BOOTGRUB contains 4 sectors, i.e., 2048 bytes. Optionally, you may
copy the 2nd, 3rd and 4th sectors of BOOTGRUB to the three sectors that
immediately follow the MBR. Also Optionally, you may copy 446 bytes
from the very beginning of BOOTGRUB to the very beginning of MBR. In
this way, the GRLDR can be started out of MBR, without the presence of
NTLDR.
CAUTION: Don't copy 512 bytes to MBR. The partition table should not
be overwritten. The partition table is in the end of MBR. If you make
a mistake, you will lose your whole system!!
2004-02-18 version 0.2.0pre4
Arbitrary-size floppy and hard disk emulation finally implemented.
GRUB for NTLDR is included. See README file.
Splash image version is available in the SPLASH directory.
2003-09-23 version 0.1.4 -- development unstable release
Unfortunately 0.1.3 has an ugly bug. Fixed.
2003-09-01 version 0.1.3 -- development unstable release
Rewrite the code for guessing FreeDOS int vectors. Hopefully it works
for all the future versions of FreeDOS :-)
2003-08-25 version 0.1.2 -- development unstable release
Fixed a small bug that affects the read of the emulated floppy sectors.
Added some files (including the menu.lst file) for installing GRUB to
MBR from DOS. Usage:
Copy the boot directory to C:\ ; You must do this on Windows, NOT dos,
because DOS cannot deal with the long filenames.
Run grub to access the menu.lst file in C:\boot\grub ; Of cause on DOS.
When menu occurs, select a proper menu item for installing GRUB to MBR.
If the menu does not appear, you should get the "grub>" prompt. At the
prompt, type the following commands:
grub> configfile (hd0,1)/boot/grub/menu.lst
grub> configfile (hd0,2)/boot/grub/menu.lst
grub> configfile (hd0,3)/boot/grub/menu.lst
Then, the menu should occur.
2003-06-29 version 0.1.0.1 -- development unstable release
Do some cleanups on 0.1.0, no important changes.
BTW, it seems that the 0.1.0 is quite stable :-)
2003-06-29 version 0.0.8
Restore mapped int13 to the unmapped state while grub is invoked
after a previously performed drive map operation.
2003-05-29 version 0.1.0 -- development unstable release
Floppy 1.44M drive emulation are OK. GOOD!!!! Usage:
# boot Windows 98 SE
map (hd1,0)/dos98se.img (fd0)
chainloader (hd1,0)/dos98se.img
rootnoverify (fd0)
boot
Another example:
# boot Mandrake hard disk installer
map (hd0,0)/hd.img (fd0)
chainloader (hd0,0)/hd.img
rootnoverify (fd0)
boot
Note that the floppy image file must size 1440KB, i.e., 1474560 bytes.
_AND_ also, the file must consist of one contiguous disk area, no
holes, no fragments. Use GRUB's blocklist command to determine whether
or not an image file is contiguous. It is known that a 1440KB-file is
always non-contiguous if it resides in an ext2 filesystem. But you may
get a 1440KB contiguous file with an FAT32 partition(vfat filesystem).
Floppy(and hard disk) with arbitrary sizes will be emulated in the
future.
2003-05-06 version 0.0.7
Fixed a huge bug!! Read the following carefully!
Using the drive map command(just as many distributions currently do)
map TO_DRIVE FROM_DRIVE
to boot your system could seriously _damage_ your hard disk data,
totally and thoroughly!! This bug has just been fixed in 0.0.7 :-)
This bug is not specific to grub_for_dos, but caused by the original
grub-0.93 release. So do _NOT_ use map command any more until my fix is
accepted by GRUB maintainers or a similar fix is made by other
people. For now, do _NOT_ use map command in any kind of Linux
distributions such as Red Hat or Mandrake or any others.
Because GRUB_FOR_DOS-0.0.7 already applied the fix, so it
should be safe to use the map command.
Another small bug was also fixed in grub_for_dos-0.0.7 :-)
2003-04-29 version 0.0.6
Runs also on MS-DOS 3.30. No other changes.
2003-04-26 version 0.0.5
Runs on MS-DOS 4.0, 5.0, 6.0, 6.20, 6.21, 6.22, 7.0, 7.10, 8.0 and
FreeDOS(build 2029). GOOD!!
2003-04-20 version 0.0.4
Running on FreeDOS(build 2029), GOOD!! (But currently GRUB.EXE only
has limited FreeDOS support, maybe unstable.)
Add a "Guess DOS Version" feature. The program now exit to DOS when
guess failed. The previous versions of GRUB.EXE always hang when
running on an unsupported DOS version.
2003-04-13 version 0.0.3
The option "--config-file=FILE" was added.
2003-04-11 version 0.0.2
Also runs on MS-DOS 8.0 (i.e., the DOS with WinMe/2000/XP), GOOD!!
The GRUB.PIF file included, so GRUB.EXE can be started from Windows 9x
2003-04-10 version 0.0.1
Runs on MS-DOS 7.10(Win98)
