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.

Note: 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 and MAC address will be cleared only if the CMOS
battery is removed.
