Jumpers Setup

The illustration shows how jumpers are setup.

When the jumper cap is placed on pins, the

jumper is "Short". If no jumper cap is placed on

pins, the jumper is "Open". The illustration

shows a 3-pin jumper whose pin1 and

pin2 are "Short" when jumper cap is placed on

these 2 pins.

Jumper

PS2_USB_PW1

(see p.2, No. 1)

Note: To select +5VSB, it requires 2 Amp and higher standby current provided by

power supply.

Clear CMOS Jumper

(CLRCMOS1)

(see p.2, No. 22)

Default

Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS includes

system setup information such as system password, date, time, and system

setup parameters. To clear and reset the system parameters to default setup,

please turn off the computer and unplug the power cord from the power supply.

After waiting for 15 seconds, use a jumper cap to short pin2 and pin3 on CLRCMOS1

for 5 seconds. However, please do not clear the CMOS right after you update the

BIOS. If you need to clear the CMOS when you just finish updating the BIOS, you

must boot up the system first, and then shut it down before you do the clear-

CMOS action.
