System Setup

Overview

CAUTION: Unless you are an expert computer user, do not change the
settings in the system setup program. Certain changes can make your
computer work incorrectly.
NOTE: Before you change system setup, it is recommended that you
write down the system setup screen information for future reference.
Use system setup 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 System Setup

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.
