The motherboard provides one jumper for you to set the computer’s
function. This section will explain how to change your motherboard’s function
through the use of the jumper.
Clear CMOS Jumper: JBAT1
There is a CMOS RAM on board that has a power supply from external
battery to keep the system configuration data. With the CMOS RAM, the system
can automatically boot OS every time it is turned on. That battery has long life
time for at least 5 years. If you want to clear the system configuration, use the
JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions below to
clear the data:
You can clear CMOS by shorting 2-3 pin while the system is off.
Then return to 1-2 pin position. Avoid clearing the CMOS while the
system is on; it will damage the mainboard.
