Changes:

  • Building the BIOS now works again.
  • Added a new IDE device type/transfer mode for use only with XT-IDE rev 2+ (or Chuck(G)-modded rev 1) cards installed in any of the following machines: Olivetti M24, AT&T PC6300, Xerox 6060 and Logabax Persona 1600. This new transfer mode is slightly faster than the regular XT-IDE rev 1 device type and requires that the card is configured for High Speed mode (or, in case of the card being a rev 1 card, has the Chuck(G) mod done). The new device type is called "XTIDE rev 2 (Olivetti M24)" in XTIDECFG.
  • Made some minor improvements to the library code that handles 'Drive Not Ready' errors in XTIDECFG.
  • Optimizations.
