Chapter 3: BIOS Setup

3.1. About the BIOS

The BIOS is the basic input/output system, the firmware on the motherboard that

enables your hardware to interface with your software. The BIOS determines what a

computer can do without accessing programs from a disk. The BIOS contains all the

code required to control the keyboard, display screen, disk drives, serial

communications, and a number of miscellaneous functions. This chapter describes

the various BIOS settings that can be used to configure your system.

The BIOS section of this manual is subject to change without notice and is provided

for reference purposes only. The settings and configurations of the BIOS are current

at the time of print and are subject to change, and therefore may not match exactly

what is displayed on screen.

This section describes the BIOS setup program. The setup program lets you modify

basic configuration settings. The settings are then stored in a dedicated, battery-

backed memory (called NVRAM) that retains the information even when the power

is turned off.

To start the BIOS setup utility:

1. Turn on or reboot your system.

2. Press <F2> during POST (F4 on remote console) to start the BIOS setup utility.
