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 (also known as a 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.Locate the Clear CMOS/Recovery jumper on the system board. See “Identifying parts on the system board” on page 11.

4.If necessary, refer to Installing adapters 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.Replace the computer cover. See “Closing the cover and connecting the cables” on page 20.

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

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

9.After the update session is completed, there will be no video and the series of beeps will end and the system will automatically turn off. Remove the diskette from the diskette drive, and turn off the computer and monitor.

10.Repeat steps 2 through 4.

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

12.Replace any adapters that were removed.
