2.8 Jumpers Setup The illustration shows how jumpers are setup. When the jumper cap is placed on pins, the jumper is "Short". If no jumper cap is placed on pins, the jumper is "Open". The illustration shows a 3-pin jumper whose pin1 and pin2 are "Short" when jumper cap is placed on these 2 pins. Jumper Setting Clear CMOS Jumper (CLRCMOS1) (see p.12, No. 22) Default Clear CMOS Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS includes system setup information such as system password, date, time, and system setup parameters. 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 finished updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action. 29

Jumpers Setup
The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration shows a 3-pin jumper whose
pin1 and
pin2 are “Short” when jumper cap
is placed on these 2 pins.

Clear CMOS Jumper
(CLRCMOS1)
(see p.12,
No. 22)
Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS in-
cludes system setup information such as system password, date, time, and
system setup parameters. To clear and reset the system parameters to de-
fault 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
nished updating the BIOS, you must boot up the system
rst, and
then shut it down before you do the clear-CMOS action.
