computer's function. This section will mention how to change your
mainboard's function through the use of jumpers.
Clear CMOS Jumper: JBAT1
There is a CMOS RAM on board that has a power supply from
external battery to keep the data of system configuration. With the CMOS
RAM, the system can automatically boot OS every time you turn on the
computer. If you want to clear the system configuration, you can use the
JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions be-
low to operate:
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.
