3.1.1 CMOS RAM auto-backup and restore
The CMOS RAM is powered by an onboard button cell battery. When
BIOS CMOS Setup has been completed, CMOS RAM data is automati-
cally backed up to Flash ROM. If conditions in a harsh industrial enviro-
ment cause a soft error, BIOS will recheck the data and automatically
restore the original data for booting.

Note:
If you intend to change the CMOS setting without restoring
the previous backup, you have to click on “DEL” within two
seconds of the “CMOS checksum error....” display screen
message 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.
