Recovering from a BIOS update failure

If the power to your server is interrupted while the BIOS is being updated, your server might not restart
correctly. If this happens, perform the following procedure to recover from the BIOS update failure.
Note: If the operating system of your server is installed under EFI mode, you need to reinstall the operating
system after recovering the BIOS.
To recover from a BIOS update failure, do the following:
1. Go to http://www.lenovo.com/drivers and follow the instructions on the Web page to download a BIOS
update package. Then, put the amiboot.rom file contained in the package into the root directory of
a bootable USB key.
2. 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.
3. Remove the server cover. See "Removing the server cover" on page 77.
4. Locate the BIOS recovery jumper on the system board. See "System board jumpers and TMM status
LED" on page 46. Then, remove any parts and disconnect any cables that might impede your access to
the jumper.
5. Move the BIOS recovery jumper from the default normal position (pin 1 and pin 2) to the short-circuited
position (pin 2 and pin 3).
6. Reinstall any parts and reconnect any cables. Then, reinstall the server cover. See "Completing the
parts replacement" on page 178.
7. Connect the server to an ac power source, and then start the server from the bootable USB key that
contains the amiboot.rom file. The recovery process starts. After the recovery process is completed,
your server will automatically turn off.
8. Repeat step 2 through step 4.
9. Move the BIOS recovery jumper back to the normal position (pin 1 and pin 2).
10. Repeat step 6.
11. Connect the server to an ac power source and turn on the server. The BIOS settings recover to the
factory default settings. You need to check and configure the BIOS settings for your specific needs. See
"Using the Setup Utility program" on page 53.

(ROM) might be damaged and you need to replace the system board. Contact the Lenovo Customer
