source: xtideuniversalbios/trunk/XTIDE_Universal_BIOS/Src/Device/IDE/IdeDPT.asm@ 596

Last change on this file since 596 was 596, checked in by Krister Nordvall, 6 years ago

Changes:

  • Made changes to HotkeyBar.asm to give the Boot Menu and Hotkey Bar a more consistent look. It will probably seem a bit strange at first to people used to the classic theme.
  • Added the missing parts of USE_NEC_V that should have been committed with the rest in r593.
  • Removed DEFINES_ALL_FEATURES from the BIOS makefile. It didn't work anymore and never really made sense anyway. Added all the official builds to 'make unused' instead which actually uncovered some unused code in the Tiny build.
  • XTIDECFG will no longer load color themes from unrecognized versions of the BIOS.
  • Other fixes in comments and some minor optimizations.
