key, the CPU will wake-up and the LED indicator will automatically stop blinking
and remain on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, it will function like a normal

Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button. When the user presses the power button, the system will enter
a SoftOff state. The monitor will be suspended and the hard drive will spin down.
Pressing the power button again to wake-up the whole system. During the SoftOff
state, the ATX power supply provides power the system to keep the required cir-
cuitry "alive". In case the system malfunctions and you want to turn off the power,
just press and hold the power button for 4 seconds. The power will turn off and no
power will be provided to the motherboard.
Wake-On-LAN (WOL)
Wake-On-LAN is defined as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and asset
tracking can occur after hours and on weekends so that daily LAN traffic is kept to
a minimum and users are not interrupted. The motherboard has a 3-pin header
(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has
WOL capability. In addition, an onboard LAN controller can also support WOL
without any connection to the WOL header. The 3-pin WOL header is to be used
with a LAN add-on card only.
Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power
supply.
1-5 Power Supply
As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates of 1 GHz and faster.
The
X8ST3-F/X8STE accommodates ATX12V standard power supplies.
Although most power supplies generally meet the specifications required by the
CPU, some are inadequate. A 2-Amp of current supply on a 5V Standby rail is
strongly recommended.
