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).

 ; Int 13h function AH=15h, Read Disk Drive Size.

+; It is unclear what is the total number of sectors to return.
+; Award BIOS from 1997 returns full capacity instead of L-CHS limit
+; like we do. I think it makes more sense if this function returns
+; L-CHS limit.
