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 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
