Clear CMOS Jumper: JCMOS1
There is a CMOS RAM onboard that has a power supply from external battery
to keep the data of system configuration. With the CMOS RAM, the system can
automatically boot OS every time it is turned on. If you want to clear the system
configuration, set the JCMOS1 (Clear CMOS Jumper ) to clear data.

MSI Reminds You...
To clear CMOS you should:
1. switch off the system and short 2-3 pin of the JCMOS1;
2. switch on the system again and the message “CMOS checksum
error” should appear;
3. switch off the system and return to 1-2 pin (Keep Data) position;
4. switch on again for operation.
Please avoid clearing CMOS while the system is on; it will damage
the mainboard.
