(7). CCMOS1 Header: CMOS Discharge Jumper
Jumper CCMOS1 used to discharge CMOS memory.
When you install the motherboard, make sure this
jumper is set for normal operation (pin 1 and 2
shorted). See figure below.
Note: Watch the pin position and the orientation
Note
Before you clear the CMOS, you have to first turn the power off (including the +5V standby power).
Otherwise, your system may work abnormally.
After updating your BIOS and before boot up, please clear the CMOS first. Then put the jumper to its
default position. After that, you can reboot your system and ensure that your system is working fine.
