#### Clearing the Sun Fire X4640 Server CMOS Settings

These procedures describe hardware-level methods for clearing the CMOS chip and resetting the BIOS settings to the factory defaults. Use these procedures when troubleshooting, when instructed by service personnel, or when called out in a procedure. Clearing the CMOS chip deletes all customized BIOS settings. Loss of customized BIOS settings might render your server incapable of operating correctly in your environment. If you customized your BIOS settings, you need to access the BIOS Setup utility (after you clear the CMOS chip) and enter the settings into the BIOS again.
