History/Future

• What's new
• Fixed bugs
• Bugs
• TODO

0.8:
• More documentation
• Minor enhancements
• MBR rewrite should now work for hda.
• Necessary modifications to Visual Chos.
0.73 (development release):
HD/FD swap
• Dos4Boot
• I even started documentating it in HTML !!!
• Configuration file:
  chos.bsect + chos.loader -> bindir
  chos.background -> bgfile
  chos.map -> mapfile
0.72 (development release):
• A few minor bugs were fixed.
• Bootsector modification feature for fooling some stupid operating systems.
• Visual Chos - configuration editor for X.
• '-view' option and 'showscreen'
0.71:
• Major bug fix. Should now work some people for whom it didn't before. See bugs that've been fixed.
0.7:
• New config file image description format, which can be extended to new options more easily.
• No more need to precede colons on the linux command line with backslashes :).
• Emergency bootsector is no longer compiled in by default (There's space for strings in the bootsector).
• See Bugs that've been fixed.
• It now sets environment variable BOOT_IMAGE automagically
• It now also passes "auto" on the command line if booted automagically (i.e. not started with space and given command line manually)
• Let's you specify hotkey and position of each image on screen.
• fastboot option
• bzImage (high-loaded (at 1M) kernel) support
• initrd (initial ramdisk) support
• new sample background piccy (a lot better than the old)
0.63:
• Added options to specify map file/loader/boot sector/ background file in the config. file.
• The map file is now written on disk when it's ready, not sector at a time (safer).
• U can now have colons on the linux command line by preceding 'em with backslashes.
0.61:
• New more portable (and smaller) map file format.
• After lots of whining from people 'round the world you now get the sources too =)
• New installation script
0.6:
• Emergency boot sector support - Choose-OS can now be configured to load an "emergency" boot sector if it can't load it's own 2nd stage, map file or background.
• Background image support.
• Options to specify menu/timer position.

0.8:
• Removed cylinder check in read_linear (sources/loader/int13.S).
  That is because some bioses seem to return too small cylinder counts while bigger values still being valid. (It returns 765 when it should return 766 and actual cylinder count is 767 (LBA)).
  If you want the check add -DCHECK_CYLINDER in sources/Makefile.
0.72:
• There was a typo in bg.c
• It didn't compile with -DHAVE_EMERGENCY. That's 'cos I never tried the feature after changing chos a lot.
0.71:
• Fixed a bug that could result in 'DIVIDE OVERFLOW' if linear sector address was creater than 65535 * sectors_per_cylinder. (e.g. with 63 sectors/cylinder linear address was creater than 63*65535=4128705, which is about 2Gb). I changed to using 64-bit arithmetic and now it seems to work...
0.7:
• With some hardware configurations noise was displayed in the background image when directly loaded disk->video memory. Compile with -DBUG_HARDWARE to use a buffer to prevent this problem.
0.62:
• Fixed a typo (there was 'x' where there should've been 'y'), which didn't let you have menu x pos>30 or something...
0.41:
• When you booted to DOS, system time was set to 00:00:00 !!! Fixed that. (Well it was set zero when you booted to Linux too, but as linux is wiser, it reads time from CMOS and everything worked ok.)
0.4:
• U can no longer fool Choose-OS to use loader and/or boot sector of previous incompatible version of Choose-OS.
