Chapter 5: BIOS Setup
5.1 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
<
Del>
or <
F2
> during POST (
Del
on remote console) to start the BIOS
setup utility.
