Last change on this file since 397 was 397, checked in by aitotat@…, 13 years ago

Changes to XTIDE Universal BIOS:

  • Cleaned some code concerning recent module changes.
  • Removed drive number translation flag from ROMVARS.
  • BOOTMENUINFO is now DRVDETECTINFO.
  • Makefile now builds tiny binary (XT build with minimal features).
