When you select Enabled, a PME signal from PCI card returns the system to Full
On state.

PWRON After PWR-Fail
This field determines the action the system will automatically take when power is
restored to a system that had lost power previously without any subsequent
manual intervention. There are 3 sources that provide current to the CMOS area
that retains these Power-On instructions; the motherboard battery (3V), the Power
Supply (5VSB), and the Power Supply (3.3V). While AC is not supplying power,
the motherboard uses the motherboard battery (3V). If AC power is supplied and
the Power Supply is not turned on, 5VSB from the Power Supply is used. When
the Power Supply is eventually turned on 3.3V from the Power Supply will be
used.
There are 3 options: "Former-Sts", "On", "Off".
"Former-Sts" (default)
"On"
"Off"
Means to maintain the last status of the CMOS
when AC power is lost.
Means always set CMOS to the "On" status when
AC power is lost
Means always set CMOS to the "Off" status when
AC power is lost.
