Recovering from a POST/BIOS update failure

If power to your computer is interrupted while POST/BIOS is being updated (flash update), your computer might not restart correctly. If this happens, perform the following procedure commonly called Boot-block Recovery.

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 10.

3.Access the system board. See “Accessing system board components and drives” on page 12.

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

5.Remove any cables that impede access to the Clear CMOS/Recovery jumper.

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

7.Reinstall the PCI riser assembly if removed.

8.Close the computer cover and reconnect any cables that were disconnected. See “Closing the cover and connecting the cables” on page 25.

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

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

11.The recovery session will take two to three minutes. During this time you will hear a series of beeps. After the update session is completed, there will be no video, the series of beeps will end, and the system will automatically turn off. Remove the diskette from the diskette drive.

12.Repeat steps 2 through 5.

13.Replace the Clear CMOS/Recovery jumper to its original position.

14.Reinstall the PCI riser assembly if removed.

15.Close the computer cover and reconnect any cables that were disconnected.
