Recovering from a BIOS update failure

If the power to your server is interrupted while the POST and BIOS is being updated, your server might not

restart correctly. If this happens, perform the following procedure to recover from the POST and BIOS

update failure. This procedure is commonly called Boot-block Recovery.

1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all

power cords from electrical outlets and disconnect all cables that are connected to the server.

2. Remove the server cover. See "Removing the server cover" on page 37.

3. Locate the Clear CMOS /Recovery jumper on the system board. See "Locating parts on the system

board" on page 15.

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

5. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 and

pin 3).

6. Reconnect any cables that were disconnected and reinstall the PCI card if removed.

7. Reinstall the server cover and reconnect the power cords for the server and monitor to electrical outlets.

See "Completing the parts replacement" on page 82.

8. Turn on the server and then insert the POST and BIOS update (flash update) disc into the optical

drive. The recovery session begins. The recovery session will take two to three minutes. During this

time, you will hear a series of beeps.

9. After the recovery session is completed, the series of beeps will end, and the system will automatically

turn off. Remove the disc from the optical drive before the system completely turns off.

10. Repeat step 1 through step 4.

11. Move the Clear CMOS /Recovery jumper back to the standard position (pin 1 and pin 2).

12. Reconnect any cables that were disconnected and reinstall the PCI card if removed.

13. Reinstall the server cover and reconnect any cables that were disconnected.

14. Turn on the server to restart the operating system.
