JCMOS1: Clear CMOS Jumper
This jumper switch, JCMOS1, clears the CMOS Setup configuration that is stored in the real-time

changed to an unsuitable configuration, the motherboard may not work properly.
JCMOS1lets you delete the configuration data stored in CMOS memory and reset the CMOS to
the Optimized Defaults.
Follow the procedure below to clear CMOS memory.
1.
Turn off and unplug the system and remove the system housing cover.
2.
Set JCMOS1 to the Clear CMOS position by placing the jumper cap over pins 2 and 3 for
one minute.
3.
Return the jumper cap to the Normal setting, pins 1 and 2.
4.
Replace the system housing cover, plug in the system and power on.
5.
Run the CMOS Setup Utility and load the Optimized Defaults. Make any custom settings
you require. (See Chapter 4, BIOS Settings.)
6.
Save the settings as you exit the program and restart your computer.
