■ chapter 2 bios setup and security feature
The Setup Utility is a hardware configuration program built into
your computer’s BIOS (Basic Input/Output System). It runs and
maintains a variety of hardware functions. It is a menu-driven
software, which allows you to easily configure and change the
settings.
The BIOS contains manufacture’s default settings for the
computer’s standard operations. However, there are occasions
when you may be required to modify the default settings in the
BIOS. For example, you may need to configure the BIOS power
management (APM) settings if you are using DOS, or
non-Windows operating system.
The BIOS allows you to set up passwords to limit access to users.
This is an important feature because a great deal of vital
information is carried within the computer nowadays. Unauthorized
access can be prevented. Later in this chapter, you will learn how to
use this security feature.

Using Password Protection
Two Levels of Password Protection are available. The BIOS
provides both a Supervisor and a User password. If you try to
activate both passwords, the Supervisor password must be set first.
The passwords activate two different levels of protection:
1. System always asks for password every time it is powered on.
2. System asks for password only when you attempt to enter

The passwords are encrypted and stored in NVRAM. Make sure
