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.
