CAUTION: Unless you are an expert computer user, do not change the settings in the BIOS Setup program. Certain

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
Steps
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.
Navigation keys
NOTE: For most of the System Setup options, changes that you make are recorded but do not take effect until you
restart the system.
