BIOS setup program
Overview
CAUTION: Unless you are an expert computer user, do not change the settings in the BIOS setup
program. Certain changes can make your computer work incorrectly.
NOTE: Before you change BIOS setup program, it is recommended that you write down the BIOS
setup program screen information for future reference.
Use BIOS setup program to:
• Get information about the hardware installed in your computer, such as the amount of RAM, the size
of the hard drive, and so on.
• Change the system configuration information.
• Set or change a user-selectable option, such as the user password, type of hard drive installed,
enabling or disabling base devices, and so on.
Entering BIOS setup program
1. Turn on (or restart) your computer.
2. During POST, when the DELL logo is displayed, watch for the F2 prompt to appear and then press F2
immediately.
NOTE: The F2 prompt indicates that the keyboard has initialized. This prompt can appear very
quickly, so you must watch for it, and then press F2. If you press F2 before the F2 prompt, this
keystroke is lost. If you wait too long and the operating system logo appears, continue to wait
until you see the operating system’s desktop. Then, turn off your computer and try again.
