Power On/Off State (ATX power only)
Refer to Table 2-17 on how to set JP20. Save Power Down (PD)
State is the default and is used when you want the system to re-
main in the power-off state when you first apply power to the system
or when the system comes back from an AC power failure. PIIX4
control is used if you want the system to be in the power-on state
the first time you apply power to the system or when the system
comes back from an AC power failure. When set to 2-3, the system
will remain off when AC power returns.
