2.3  Jumpers Setup

The 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 “Open”. The illustration shows a 3-pin jumper whose pin1 and pin2 are “Short” 

when a jumper cap is placed on these 2 pins.

Clear CMOS Jumper
(CLRMOS1)
(see p.1, No. 16)

CLRMOS1 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 CLRMOS1 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. Please be noted that the password, 
date, time, and user default profile will be cleared only if the CMOS battery is 
removed.
