About BIOS Setup
The BIOS (Basic Input and Output System) Setup program is a menu
driven utility that enables you to make changes to the system
configuration and tailor your system to suit your individual work
needs. It is a ROM-based configuration utility that displays the
systems configuration status and provides you with a tool to set
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 configured with the
values found in CMOS.
With easy -to -use pull down menus, you can configure such items as:
. Hard drives, diskette drives, and peripherals
. Vide o display type and display options
. Password protection from unauthorized use
. Power management features
The settings made in the setup program affect how the computer
performs. It is important, therefore, first to try to understand all the
setup options, and second, to make settings appropriate for the way
you use the computer.
When to Configure the BIOS
. This program should be executed under the following conditions:
. When changing the system configuration
. When a configuration error is detec ted by the system and
you are prompted to make changes to the setup program
. When resetting the system clock
. When redefining the communication ports to prevent any conflicts
. When making changes to the Power Management configuration . When changing the password or making other changes to the
Normally, CMOS setup is needed when the system hardware is not
consistent with the information contained in t he CMOS RAM,
whenever 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 setting s 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:
. If the error occurs before the display device is initialized, a series of
beeps will be transmitted.
. If the error occurs after the display device is initialized, the
screen will display the error message.
Powering on the computer and immediately pressing allows
you to enter Setup. Another way to enter Setup is to power on the
computer and wait for the following message during the POST:
