source: xtideuniversalbios/trunk/XTIDE_Universal_BIOS/Src/Device/Serial/SerialDPT.asm @ 567

Last change on this file since 567 was 567, checked in by krille_n_@…, 10 years ago

Changes:

  • Renamed MODULE_FEATURE_SETS to MODULE_POWER_MANAGEMENT.
  • Renamed MODULE_VERY_LATE_INITIALIZATION to MODULE_VERY_LATE_INIT and removed it from the official builds.
  • Removed the code that skips detection of slave drives on XT-CF controllers since slave drives can be used with Lo-tech ISA CompactFlash boards.
  • Added autodetection of the SVC ADP50L controller to XTIDECFG.
  • The autodetection of XT-CF controllers now requires MODULE_8BIT_IDE_ADVANCED in the loaded BIOS.
  • Fixed a bug in XTIDECFG from r502 where the "Base (cmd block) address" menu option would be displayed when a serial device was selected as the IDE controller.
  • XTIDECFG would display the "Enable interrupt" menu option for the XTIDE r1 but not for the XTIDE r2. It's now displayed for both controller types.
  • Disabled the "Internal Write Cache" menu option in the Master/Slave Drive menus for serial device type drives.
  • Optimizations and other fixes.
