Changes to XTIDE Universal BIOS:

• Hotkeys were incorrectly initialized to use 'C' as first hard drive letter.
• All CHS translate modes should again work (incorrectly decremented DX instead of DL, it might or might not have caused problems).

Location:

trunk/XTIDE_Universal_BIOS/Src/Menus

Files:

• DriveXlate.asm (modified) (3 diffs)
• HotkeyBar.asm (modified) (2 diffs)
