2.5 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”.
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 the
pins 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. Please
remember toremove the jumper cap after clearing the CMOS.
2.6 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over
these headers and connectors. Placing jumper caps over the headers and connectors
will cause permanent damage to the motherboard.
