1.Turn off the computer and any attached devices, such as printers, monitors, and external drives.

2.Unplug all power cords from electrical outlets, and open the computer cover. See “Opening the cover” on page 11.

3.Locate the Clear CMOS/Recovery jumper on the system board. See “Identifying parts on the system board” on page 13.

4.If necessary, see “Installing PCI adapters” on page 15 to remove any adapters that impede access to the Clear CMOS/Recovery jumper.

5.Move the jumper from the standard position (pins 1 and 2) to pins 2 and 3.

6.Reinstall the PCI riser assembly if removed.

7.Close the computer cover and reconnect any cables that were disconnected. See “Closing the cover and connecting the cables” on page 28.

8.Reconnect the power cords for the computer and monitor to electrical outlets.

9.Insert the POST/BIOS update (flash) diskette into drive A, and turn on the computer and the monitor.
