Flashing the BIOS From a CD
1 Turn on your computer.
2 Press the eject button on the front of the optical drive to open the drive
tray.
3 Place the BIOS-update disc in the center of the drive tray, and then press
the eject button or gently push on the tray to close it.
4 Restart the computer.
5 When the DELL™ logo appears, press <F12> immediately.
NOTE: Keyboard failure may result when a key on the keyboard is held down
for extended periods of time. To avoid possible keyboard failure, press and
release <F12> in even intervals until the Boot Device Menu appears.
If you wait too long and the operating system logo appears, continue to
wait until you see the Microsoft
®
Windows
®
desktop, and then shut down
your computer and try again.
6 At the Boot Device Menu, use the up- and down-arrow keys, or press the
appropriate number on the keyboard to highlight Onboard or USB CD-
ROM, and then press <Enter>.
NOTE: The one time boot menu feature changes the boot sequence for the
current boot only. Upon restart, the computer boots according to the boot
sequence specified in the system setup program.
CAUTION: Do not interrupt this process once it begins. Doing so may damage the
system.
7 Follow the instructions that appear on the screen. The computer continues
to boot and updates the new BIOS. When the flash update is complete,
the computer automatically reboots.
8 Remove the flash BIOS update program CD from the drive.
