Changes:

  • Added Power Management (Standby Timer) support to the BIOS and made it part of an optional module (MODULE_FEATURE_SETS). The total amount of ROM space used by this feature is 37 bytes. UNTESTED
  • Size optimizations (mostly inlining of procedures) and fixed a few bugs in AH9h_HInit.asm:
    1. DPT_ATA.bInitError would be cleared only if MODULE_SERIAL was not defined.
    2. The FLG_INITERROR_FAILED_TO_SET_BLOCK_MODE flag could never be set.
    3. InitializeBlockMode could potentially loop forever if there was an error.
  • Removed some odd looking code in .PushResetStatus in BootMenuPrintCfg.asm
  • Made some changes to XTIDECFG so it can be built.
