The illustration shows how jumpers are

setup. When the jumper cap is placed on

is placed on these 2 pins.

Jumper Setting Description

Clear CMOS Jumper

(CLRCMOS1)

(see p.2, No. 33)

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 proﬁ le, 1394

GUID and MAC address will be cleared only if the CMOS battery is removed.

Clear CMOSDefault

If you clear the CMOS, the case open may be detected. Please adjust

the BIOS option “Clear Status” to clear the record of previous chassis

intrusion status.
