4.1 Introduction
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 the operation of
your notebook to your individual work needs. A ROM-based configuration utility displays
the system’s configuration status and provides you with a tool to set system parameters.
The set parameters are stored in nonvolatile battery backed-up CMOS RAM, which saves
this information even when the power is turned off. When the computer is turned back on,
the system is configured with the values found in CMOS. Via easy-to-use menus, you can
configure such items as:
Boot devices
The settings made in the Setup program intimately affect how your notebook performs. It
is important, therefore, to first understand all the available options, and second, to make
settings appropriate for the way you use your notebook. This chapter guides you through
the Setup program by providing the clear explanations for all Setup options.
A standard configuration has already been set in the Setup program by the factory
technicians. However, eventually you may want to customize your system to suit your own
performance needs. It is recommended that you read this chapter and become familiar
with the configurations that can be made in the BIOS.
The next section explains how to move around in the Setup program, as well as how to
specify and save your new settings. A brief discussion of the optional settings among the
different submenus follows.
