Using the Setup Utility program
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. Ensure that your computer is turned off.
2. Repeatedly press and release the F1 key when turning on the computer. When you hear multiple
beeps or see a logo screen, release the F1 key.
Note: If a power-on password or an administrator password has been set, the Setup Utility program
menu will not be displayed until you enter the correct password. For more information, see “Using
BIOS passwords” on page 66.
When the POST detects that the hard disk drive has been removed from your computer or the memory size
has decreased, an error message will be displayed. You must do one of the following:
• Press F1 to enter the Setup Utility program.

program. Press Enter when prompted to confirm the exit. The error message will not be displayed again.
• Press F2 to bypass the error message and log in to the operating system.

the hard disk drive. To enable the configuration change detection feature, do the following:
1. Start the Setup Utility program.
