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 cover. See “Opening the cover” on page 10.

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

4.If necessary, refer to “Accessing system board components and drives” on page 12 to gain access to the Clear CMOS/BIOS Recovery jumper.

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

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

7.Replace any cables or adapters that were removed.

8.Close the cover. 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.During the update session there will be no video. You will hear a long beep when recovery is completed. Remove the diskette from the diskette drive, and turn off the computer and monitor.

12.Unplug the power cords from electrical outlets.

13.Open the cover. See “Opening the cover” on page 10.

14.Remove any cables or adapters that impede access to the Clear CMOS/BIOS Recovery jumper.

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