Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blink-

ing to indicate that the CPU is in the suspend mode. When the user presses any

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

keyboard during system boot-up.

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

dard power supplies. Although most power supplies generally meet the specifica-
