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 system’s
configuration 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 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
• Video 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 detected 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 security setup
Normally, CMOS setup is needed when the system
hardware is not consistent with the information contained
in the CMOS RAM, whenever the CMOS RAM has lost
power, or the system features need to be changed.
