and Play functions of a computer. The use of ACPI with this board requires an

operating system that provides full ACPI support. ACPI features include:

• Plug and Play (including bus and device enumeration)

• Power management control of individual devices, add-in boards (some add-in

boards may require an ACPI-aware driver), video displays, and hard disk drives

• Methods for achieving less than 15-watt system operation in the power-on/standby

sleeping state

• A Soft-off feature that enables the operating system to power-off the computer

• Support for multiple wake-up events (see Table 7 on page 34)

• Support for a front panel power and sleep mode switch
