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 to start the BIOS setup utility.
