3.3.1 CMOS RAM backup

The CMOS RAM is powered by an onboard button cell battery.
When BIOS CMOS Setup has been completed, CMOS RAM data is
automatically backed up to Flash ROM. If conditions in a harsh
industrial enviroment cause a soft error, BIOS will recheck the data and
automatically restore the original data for booting.
Note: If you intend to update CMOS RAM data, you have
to click on "DEL" within two seconds of the "CMOS
checksum error...." display screen message appear-
ing. Then enter the "Setup" screen to modify the data.
If the "CMOS checksum error...." message appears
again and again, please check to see if you need to
replace the battery in your system.
