Structs§

  • Acpi
    ACPI is the successor to APM (Advanced Power Management), aiming to give the operating system more control over the hardware.

    This (usually!) contains the base address of the EBDA (Extended Bios Data Area), shifted right by 4
  • RSDP_BIOS_AREA_END 🔒
    The end of the main BIOS area below 1mb in which to search for the RSDP (Root System Description Pointer)
  • RSDP_BIOS_AREA_START 🔒
    The start of the main BIOS area below 1mb in which to search for the RSDP (Root System Description Pointer)
  • RSDP_SIGNATURE 🔒
