Clear CMOSDefault

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 nish updating the BIOS,

you must boot up the system rst, and then shut it down before you do the

clear-CMOS action. Please be noted that the password, date, time, user

default prole, 1394 GUID and MAC address will be cleared only if the

CMOS battery is removed.

2.7 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.
