Configuring BIOS Settings

This appendix describes how to view and/or modify the Basic Input/Output System (BIOS) settings on the server. The BIOS Setup Utility reports system information and can be used to configure the server BIOS settings.

Note - The BIOS menus shown in this appendix are examples. The BIOS version numbers, menu information, and menu selections are subject to change over the life of the product.

BIOS has a Setup Utility stored in the BIOS flash memory. The configured data is provided with context-sensitive Help and is stored in the system's battery-backed CMOS RAM. If the configuration stored in the CMOS RAM is invalid, the BIOS settings default to the original state specified at the factory.

The following topics are covered:

- BIOS Setup Screens Overview

- BIOS Setup Utility Menu Screens

For information on accessing BIOS, see About the BIOS.
