Chapter 5: BIOS Utilities
Overview
This chapter is about the computer’s built-in software.
Your computer comes with built-in
BIOS
(
Basic Input Output System
)
which is an essential set of software routines stored on a chip in your comput-
er. These routines serve to describe your computer’s hardware to your chosen
operating system, and provides an interface between the two. The
BIOS
in-
cludes the
POST
(
Power On Self Test
) and the
SCU
(
System Configuration
Utility
). The
POST
performs diagnostic procedures at startup, the
SCU
al-
lows you to configure your computer.
There is one general rule:
Don’t make any changes unless you are sure of
what you are doing
. Many of the settings are required by the system, and
changing them could cause it to become unstable or worse. If you have any
doubts, consult your service representative.
If your computer has never been set up, or you are making important changes
to the system, then you should review this chapter first and note the original
settings found in the
SCU
. Even if you are a beginner, keep a record of the
settings you find and any changes you make. This information could be useful
if your system ever needs servicing.
Settings Warning
Incorrect settings can
cause your system to
malfunction. To correct
mistakes return to the
SCU
, go to the
Exit
menu and select the
Default Settings
and
click
OK
.
