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

pin1 and  pin2 are “Short” when jumper cap 

is placed on these 2 pins.

Description

Clear CMOS Jumper

(CLRCMOS1)

(see p.2,  No. 22)

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

fi

 nish updating the BIOS, you must boot 

up the system 

fi

 rst, and then shut it down before you do the clear-CMOS ac-

tion. Please be noted that the password, date, time, user default pro
