BIOS setup program
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 has 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 operating system’s desktop. Then,
turn off your computer and try again.
