BIOS setup
4.1 Overview
In this chapter you will find information, required for calling the BIOS
setup and the possible settings.
The BIOS (Basic Input and Output System) setup program is a menu
driven utility that enables you to make changes to the system configu-
ration and tailor your system to suit your individual work needs. It is a
ROM-based configuration utility that displays the system’s configura-
tion status and provides you with a tool to set system parameters.
These parameters are stored in non-volatile battery-backed-up
CMOS RAM that saves this information even when the power is
turned off. When the system is turned back on, the system is config-
ured with the values found in CMOS.
With easy-to-use pull down menus, you can configure such items as:
n
Hard drives, diskette drives, and peripherals
n
Video display type and display options
n
Password protection from unauthorized use
n
Power management features
This program should be executed under the following conditions:
n
Changing the system configuration
n
A configuration error is detected by the system and you are
prompted to make changes to the setup program
n
Resetting the system clock
n
Redefining the communication ports to prevent any conflicts
n
Making changes to the power management configuration
n
Changing the password or making other changes to the security
setup
Normally, CMOS setup is needed when the system hardware is not
consistent with the information contained in the CMOS RAM, when-
ever the CMOS RAM has lost power or the system features need to
be changed.
Most of the configuration settings are either predefined according to
the
‘Load Optimal Defaults’
settings which are stored in the BIOS or
are automatically detected and configured without requiring any
actions. There are a few settings that you may need to change
depending on your system configuration.
When the system is powered on, the BIOS will enter the Power-On
Self Test (POST) routines. These routines perform various diagnostic
checks; if an error is encountered, the error will be reported in one of
two different ways:
n
If the error occurs before the display device is initialized, a series
of beeps will be transmitted.
n
If the error occurs after the display device is initialized, the screen
will display the error message.
Powering on the computer and immediately pressing
[Del]
allows you
to enter Setup.
