Clearing the BIOS configuration settings

The server BIOS configuration settings such as the system date and time, boot sequence, and hardware settings are stored in the CMOS. These settings are configured in the Aptio Setup Utility.

You might need to clear the CMOS if any of the following conditions occur:

POST errors or boot issues
Corrupted BIOS settings
Incorrect settings made in the Aptio Setup Utility have caused error messages to be unreadable.
If there is a hardware compatibility issue of a known compatible component.
If the power-on password is forgotten.

CAUTION:

Be careful when clearing or altering the BIOS settings. Changing some settings might prevent the server from booting up correctly or might result in data loss.

Clearing the CMOS resets the BIOS settings to their factory default state. To clear the CMOS:

If the Aptio Setup Utility is accessible, use the Restore Defaults option under the Save & Exit menu.
If the Aptio Setup Utility is not accessible, use the CMOS header.

After clearing the CMOS, use the Aptio Setup Utility to reconfigure the BIOS settings.
