Chapter 5. Using the Setup Utility

The Setup Utility program is used to view and change the configuration settings of

your computer, regardless of which operating system you are using. However, the

operating-system settings might override any similar settings in the Setup Utility

program.

Starting the Setup Utility program

To start the Setup Utility program, do the following:

1. If your computer is already on when you start this procedure, shut down the

operating system and turn off the computer.

2. Press and hold the F1 key then turn on the computer. When you hear multiple

beeps, release the F1 key.

Notes:

a. If you are using a USB keyboard and the Setup Utility program does not

display using this method, repeatedly press and release the F1 key rather

than leaving it pressed when turning on the computer.

b. If a user password or an administrator password has been set, the Setup

Utility program menu is not displayed until you type your password. For

more information, see “Using passwords.”

The

Setup Utility might start automatically when POST detects that hardware has

been removed or new hardware has been installed in your computer.

Viewing and changing settings

The Setup Utility program menu lists items that identify system configuration

topics. To view or change settings, see “Starting the Setup Utility program.”

When working with the Setup Utility program menu, you must use the keyboard.

The keys used to perform various tasks are displayed at the bottom of each screen.

Using passwords

By using the Setup Utility program, you can set passwords to prevent

unauthorized persons from gaining access to your computer and data. See

“Starting the Setup Utility program.” The following types of passwords are

available:

v User Password

v Administrator Password

You

do not have to set any passwords to use your computer. However, if you

decide to set any passwords, read the following sections.

Password considerations

symbols. For security reasons, it is a good idea to use a strong password that

cannot be easily compromised. Passwords should adhere to the following rules:
