CHAPTER 3 BIOS SETUP
3.1 BIOS Introduction
The BIOS (Basi
c Input/Output System) installed in your computer system’s ROM
supports Intel processors. The BIOS provides critical low-level support for a standard
device such as disk drives, serial ports and parallel ports. It also password protection
as well as special support for detailed fine-tuning of the chipset controlling the entire
system.
3.2 BIOS Setup
The BIOS provides a Setup utility program for specifying the system configurations
and settings. The BIOS ROM of the system stores the Setup utility. When you turn on
the computer, the BIOS is immediately activated. Pressing the <Del> key immediately
allows you to enter the Setup utility. If you are a little bit late pressing the <Del> key,
POST (Power On Self Test) will continue with its test routines, thus preventing you
from invoking the Setup. If you still wish to enter Setup, restart the system by pressing
the ”Reset” button or simultaneously pressing the <Ctrl>, <Alt> and <Delete> keys.
You can also restart by turning the system Off and back On again. The following
message will appear on the screen:
Press <DEL> to Enter Setup
In general, you press the arrow keys to highlight items, <Enter> to select, the <PgUp>
and <PgDn> keys to change entries, <F1> for help and <Esc> to quit.
When you enter the Setup utility, the Main Menu screen will appear on the screen.
The Main Menu allows you to select from various setup functions and exit choices.
Warning:
It is strongly recommended that you avoid making any changes to the
chipset defaults. These defaults have been carefully chosen by both
AMI and your system manufacturer to provide the absolute maximum
performance and reliability. Changing the defaults could cause the
system to become unstable and crash in some cases.
