Changes to XTIDE Universal BIOS:

• Fixed a very old bug (from r150) in IdeError.asm where GetBiosErrorCodeToAHfromStatusAndErrorRegistersInAX would return RET_HD_SEEK_FAIL instead of RET_HD_STATUSERR.
• Optimizations and other fixes.

File:

• trunk/XTIDE_Universal_BIOS/Src/Initialization/AdvancedAta/Vision.asm (modified) (3 diffs)
