source: xtideuniversalbios/trunk/Assembly_Library/Src/Menu/MenuInit.asm@ 124

Last change on this file since 124 was 116, checked in by krille_n_@…, 14 years ago

Changes to all parts of the project:

  • Removed a redundant macro (HPIO_NORMALIZE_PTR)
  • Deleted XTIDE_Universal_BIOS/Inc/BiosData.inc since that was also redundant.
  • Size optimization: Changed the LOAD_BDA_SEGMENT_TO macro to use the stack on 186+ processors (the old behaviour can still be used where needed).
  • Made other minor size optimizations and cleanups to various functions, mostly in the Int13h handler.
