1.5 Jumper 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.2, No. 31)
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, user
default profile, 1394 GUID and MAC address will be cleared only if the
CMOS battery is removed.
