Introduction
This chapter provides information related to the system BIOS
and its Setup program.
BIOS Setup Program
The BIOS (Basic Input and Output System) Setup Program is a
utility that enables you to change the system configuration and
tailor the operation of your notebook to suit individual work
needs. It is a ROM-based (Read Only Memory) utility that
displays the system’s configuration status and allows you to set
system parameters. The parameters are stored in non-volatile
battery backed-up CMOS RAM, which saves information even
when power is turned off. When power is restored, the system is
configured with the values found in CMOS.
NOTE:
The CMOS battery receives a charge when the system
is operated on AC power. If the system is off for more than one
year, the CMOS battery will drain and the ROM data will be lost.
The settings made in the Setup program affect how the
notebook performs. It is important to try to understand all the
Setup options and to make settings appropriate for the way you
use the notebook.
