4.3 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.
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 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, and
user default profile will be cleared only if the CMOS battery is removed.
