to keep the system configuration data. With the CMOS RAM, the system can automati-
cally boot OS every time it is turned on. If you want to clear the system configuration,
use the JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions below to
clear the data:
MSI Reminds You...
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.
