External Battery Connector Jnbat1 - Intel MS-6112 User Manual

A battery must be used to retain the mainboard configuration in CMOS
RAM. If you use the on-board battery, you must short 1-2 pins of JBAT1
to keep the CMOS data.
Keep Data
Note: 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.
