Clear CMOS Jumper: CLEAR_CMOS
The onboard CMOS RAM stores system configuration data and has an onboard
battery power supply. The long-life battery has a lifetime of at least 5 years.
If you want to clear the system configuration data from the CMOS RAM, use
the CLEAR_CMOS (Clear CMOS jumper). Follow the instructions below to
clear the data:
The mainboard provides jumpers for setting the mainboard’s functions. This
section will explain how to change settings for your mainboard’s functions
through the use of the jumpers.
You can clear the CMOS by shorting 1-2 pin while
the system is off. Then return it to the 2-3 pin
position. Avoid clearing the CMOS while the
system is on; this will damage the mainboard.
