Note: If you enable the ACPI function in the BIOS setup, the SMI function will not work.
ACPI requires an ACPI-aware operating system. ACPI features include:
! Plug and Play (including bus and device enumeration) and APM functionality normally contained in
the BIOS.
! Power management control of individual devices, add-in cards (some add-in cards may require an
ACPI-aware driver), video displays, and hard disk drives.
! A Soft-off feature that enables the operating system to power off the computer.
! Support for multiple wake-up events (see Table 3-6-1).
