BIOS 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 the BIOS Setup program for the following purposes:
● Get information about the hardware installed in your computer, such as the amount of RAM and the size of the hard drive.
● Change the system configuration information.
● Set or change a user-selectable option, such as the user password, type of hard drive installed, and enabling or disabling
base devices.
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 again.
