Last change on this file since 394 was 392, checked in by aitotat@…, 13 years ago

Changes to XTIDE Universal BIOS:

  • Greatly improved Hotkey Bar is displayed during drive detection.
  • 8k builds no longer include boot menu.
  • Boot menu is displayed only if F2 is pressed during drive detection.
  • Some changes to directory structure.
