If a BIOS-update program media, such as a CD, is provided with a new system board, flash the BIOS from the media. If you do not have a BIOS-update

Flashing the BIOS From a CD
1. Ensure that the AC adapter is connected to an electrical outlet and that the main battery is installed properly.
2. Start your computer.
3. Press the eject button at the front of the optical drive to open the drive tray.
4. Place the BIOS-update CD in the center of the drive tray, then gently push to close the tray.
5. Restart the computer.
6. When the DELL logo appears, press <F12> immediately.
If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft®Windows®desktop, then shut down your
computer and try again.
7. At the Boot Device Menu, use the up- and down-arrow keys or press the appropriate number on the keyboard to highlight CD-ROM, and then press
<Enter>.
8. 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.
9. Remove the flash BIOS update program CD from the drive.
