Last change on this file since 373 was 370, checked in by krille_n_@…, 13 years ago

Changes:

  • Added some missing PIO mode timings to ATA_ID.inc (based on info from ​http://www.singlix.net/specs/cfspc4_0.pdf)
  • Updated Configuration_FullMode.txt but it may need additional changes as the Tandy info doesn't match the wiki.
  • Optimizations.
  • Excluded some unused code from XTIDECFG.
