When the configuration for the BIOS firmware changes on an Oracle server, use Oracle Integrated Lights Out Manager (ILOM) to do the following:
Back up the BIOS configuration to prevent the loss of the current working configuration. For more details, see Back Up the Current BIOS Firmware Configuration (Oracle ILOM).
Recover from unwarranted configuration changes by restoring the BIOS configuration to its last saved working or factory default configuration. For more details, see Restore the Backed Up BIOS Configuration or Reset BIOS to Factory Defaults (Oracle ILOM).
Verify that the current BIOS configuration settings on the host are in sync with the configuration settings stored by Oracle ILOM. If necessary, you can sync the host BIOS settings with Oracle ILOM. For more details, see Sync the Host BIOS Firmware Configuration (Oracle ILOM).
