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

is placed on these 2 pins.

Setting Description
Clear CMOS Jumper
(CLRCMOS1)
(see p.2, No. 29)
Note: CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the sys-
tem 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, 1394 GUID and MAC
address will be cleared only if the CMOS battery is removed.
