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.

PS2_USB_PWR1

Short pin2, pin3 to enable

(see p.8,  No. 1)

+5VSB (standby) for PS/2 or

USB wake up events.

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

power  supply.

JR1 / JL1 Jumper

(see p.8,  No. 29)

Note: If the jumpers JL1 and JR1 are short, both the front panel and the rear panel

audio connectors can work.

Clear CMOS Jumper

(CLRCMOS2)

(see p.8,  No. 23)

Note: CLRCMOS2 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 the Clear

CMOS jumper for 5 seconds. After shorting the Clear CMOS jumper, please

remove the jumper cap. 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.
