JBAT1: Clear CMOS Jumper

There is CMOS RAM onboard that is external powered from a battery located on the
motherboard to save system configuration data. With the CMOS RAM, the system can
automatically boot into the operating system (OS) every time it is turned on. If you
want to clear the system configuration, set the jumpers to clear the CMOS RAM.
Important
You can clear the CMOS RAM by shorting this jumper while the system is off.
Afterwards, open the jumper. Do not clear the CMOS RAM while the system is on
because it will damage the motherboard.

conditions, to boot at a stable processor frequency and to prevent the system from

overclocking results will vary according to the CPU version.
• Please don't set this jumper to "Enabled" when power-off or the system will be un-
bootable.
