Last change on this file since 623 was 614, checked in by Krister Nordvall, 3 years ago

Changes:

  • BIOSDRVS should now build again (broke in r613).
  • Removed the NO_ATAID_CORRECTION define from the Tiny build.
  • Added a new configuration option to skip detection of slave drives.
  • Made FLASH_SIGNATURE 2 bytes shorter to free up ROM space.
  • "Auto Configure" in XTIDECFG should now detect if running on an Olivetti M24, AT&T PC6300, Xerox 6060 or Logabax Persona 1600 and automatically select the fastest compatible transfer mode/device type for any IDE controllers found in the system.
  • Cleaned out some duplicate/unused definitions.
