2.5 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.

Description
Clear CMOS Jumpers
CLRMOS1
:
(3-pin CLRMOS1)
1-2 : Normal
(see p.8, No. 19)
2-3 : Clear CMOS
Note: CLRMOS1 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 CLRMOS1 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 date, time and user default profile will be cleared
only if the CMOS battery is removed.
