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:
Š
Hard drives, diskette drives, and peripherals
Š
Video display type and display options
Š
Password protection from unauthorized use
Š
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:
Š
When changing the system configuration
Š
When a configuration error is detected by the system and you are prompted to make changes to
the Setup program
Š
When resetting the system clock
Š
When setting the CPU clock speed so that it automatically runs either fast or slow
Š
When redefining the communication ports to prevent any conflicts
Š
When making changes to the Power Management configuration
Š
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 con-
tained in the CMOS RAM, whenever the CMOS RAM has lost power, or the system features need to be
changed.
