Chapter 3: BIOS Setup

3.1 About the BIOS

The BIOS is the basic input/output system, the firmware on the motherboard that is
a hardware and software interface. 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 <Del> or <F2> during POST to start the BIOS setup utility.
