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 auto-
matically backed up to Flash ROM. If conditions in a harsh industrial
enviroment cause a soft error, BIOS will recheck the data and automati-
cally 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 mes-
sage appearing. 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.
