Changes to XTIDE Universal BIOS:

  • Added Advanced ATA Module (MODULE_ADVANCED_ATA) with native support for QDI Vision QD6500 and QD6580 VLB IDE Controllers.
  • Hopefully optimized IDE transfer functions for 8088 (replaced some memory accesses from WORD to BYTE).
  • XT build does not fit in 8k at the moment!!!
