4.1 About the BIOS

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 intimately 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.

4.2 When to Run 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.
