BIOS setup program

BIOS overview

The BIOS manages data flow between the computer's operating system and
attached devices such as hard disk, video adapter, keyboard, mouse, and printer.

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 is 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 desktop. Then, turn off your computer and try
again.
