Chapter 6. Using the Setup Utility

The Setup Utility program is stored in the electrically erasable programmable read-only memory (EEPROM)
of the computer. The Setup Utility program is used to view and change the configuration settings of the
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. Repeatedly press the F1 key as you turn on the computer.
a. If a password has been set, the Setup Utility program menu is not displayed until you type your
password. See "Using passwords" on page 47 for more information.
b. BIOS settings cannot be changed without the correct password.
c. The Setup Utility might start automatically when the power-on self-test (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.
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.

Exiting from the Setup Utility program

When you finish viewing or changing settings, press Esc to return to the Setup Utility program menu (you
might have to press Esc several times) If you want to save the new settings, press F10.

Using passwords

By using the Setup Utility program, you can set passwords to prevent unauthorized persons from gaining
access to your computer and data. The types of passwords used are:

• User Password

• 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.
User Password
When a User Password is set, the user is prompted to type a valid password each time the computer is
turned on. The computer cannot be used until a valid password is typed from the keyboard.
