Figure 3.25 PCH-IO Configuration
 PCIE Wake
To enable or disable PCIE to wake the system from S5.
 Deep Sx Power Policies
Enable or disable Deep Sx feature. When Deep Sx is enabled, most power
including 5VSB will be off during deep Sx for energy saving.
 Serial IRQ Mode
Configure Serial IRQ Mode.
 High Precision Event Timer
Enable/Disable the High Precision Event Timer.

After AC Power Loss
To select AC power state when power is re-applied after a power failure.
Note! When a system enters G3 status with deep S5 enabled, some power
supply's 5VSB won't drop until after more than 30 seconds. If "Restore
AC Power Loss" is set to "power on", the system won't boot up in 30
seconds after power failure. We recommend the user waits for more
than 30 seconds to power on after a power failure. On the other hand,
the system will auto power on if power is restored within 30 seconds,
before 5VSB actually drops, even if "Restore AC Power Loss" is set to
"power off".
