3.3 Standard CMOS Setup
Choose the “Standard CMOS Features” option from the “Initial Setup
Screen” menu, and the screen below will be displayed. This menu allows
users to configure system components such as date, time, hard disk drive,
floppy drive, display, and memory.
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 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 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.
