Changes to XTIDE Universal BIOS:

• CREATE_COMPATIBLE_DPT is now MODULE_COMPATIBLE_TABLES.
• DPTs pointed by INT 41h and INT 46h are now swapped when swapping drives 81h and 80h.
• Block mode commands are no longer used when block size is set to 1 with AH=24h.

Location:

trunk/XTIDE_Universal_BIOS/Src/VariablesAndDPTs

Files:

• CompatibleDPT.asm (modified) (4 diffs)
• CreateDPT.asm (modified) (2 diffs)
