2.3 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 illus-
tration shows a 3-pin jumper whose pin1 and
pin2 are "Short" when jumper cap is placed on
these 2 pins.

Clear CMOS Jumpers
(3-pin CLRCMOS1)
(see p.7, No. 23)
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 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, user default profile and MAC address will be cleared only if
the CMOS battery is removed.
