Setup
3.1.2 CMOS RAM Auto-backup and Restore
The CMOS RAM is powered by an onboard button cell battery. When you finish BIOS
setup, the data in CMOS RAM will be automatically backed up to flash memory. If
operation in harsh industrial environments causes a soft error, the BIOS will check
the data in CMOS RAM and automatically restore the original data from flash mem-
ory to CMOS RAM for booting.
3.2 Entering Setup
Turn on the computer and press to enter the BIOS setup.

Note! To change the CMOS setting without restoring the previous backup,
press "DEL" within two seconds of the "CMOS checksum error..." mes-
sage appearing and then use the "Setup" screen to modify the configu-
ration. If the "CMOS checksum error..." message appears again and
again, please check to see if you need to replace the battery in your sys-
tem.
Note! ATI SB600 cannot restore system date and time, once the CMOS is
cleared.
