4.3 Jumpers Setup
e 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”. e 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
(CLRCMOS1)
(see p.13, No. 30)
CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the system
parameters to default setup, please turn o the computer and unplug the power cord
from the power supply. Aer 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 aer 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, and
user default prole will be cleared only if the CMOS battery is removed.
