Jumpers Setup

e illustration shows how jumpers are setup. When the jumper cap is placed on

the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper is

“O pen”.

Clear CMOS Jumper

(CLRCMO S1)

(see p.6, No. 3)

CLRCMOS1 allows you to clear the data in CMOS. e 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 o the computer and unplug the power cord, then use a jumper cap to short

the pins on CLRCMOS1 for 3 seconds. Please remember to remove the jumper

cap aer clearing the CMOS. If you need to clear the CMOS when you just nish

updating the BIOS, you must boot up the system rst, and then shut it down

before you do the clear-CMOS action.
