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

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.

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.
