The BIOS, or Basic Input/Output System, is a program that runs and checks the status of the machine before the operating system loads. For Dell Latitude computers, the information stored in the computer's BIOS can be viewed and changed by entering the system setup program during startup. Information shown in the system setup screens include hardware configuration, the computer's boot order, start-up configuration and device configuration settings for basic system components.

Turn on the computer by pressing the power button. If the computer is already running, restart the computer by clicking "Start" and selecting "Turn Off Computer". Select "Restart" from the window that opens.
Press and hold "F2" on the computer keyboard when the Dell logo appears on the screen. The computer will enter the system setup program to display information stored in BIOS.
If the Windows logo appears, you did not press "F2" in time to enter the system setup program. Wait for the computer to finish starting up and restart the computer to try this procedure again.
Make any desired changes in the system setup program, and press "F10" to save the changes and exit the system setup program. The computer will continue to boot as normal.
