Updating (flashing) the BIOS

This topic provides instructions on how to update (flash) the BIOS.

Notes:

1.Update the BIOS on your server only if the newer BIOS version specifically solves a problem you have. We do not recommend BIOS updates for servers that do not need it. You can view the updated information for the new BIOS version in the installation instructions for the BIOS update utility program. See “Downloading the BIOS update utility program” on page 67.

2.Downgrading the BIOS to an earlier version is not recommended and might not be supported. An earlier BIOS version might not contain the support for the latest system configurations.

3.If the power to your server is interrupted while the POST and BIOS is being updated, your server might not restart correctly. Make sure that you perform the BIOS update procedure in an environment with a steady power supply. Besides, make sure that your server can restart successfully without encountering hardware problems.

4.If you have updated the BIOS firmware, all the BIOS settings become the default settings of the updated BIOS version. You need to check and reconfigure the BIOS settings for your specific needs. You

can note down your specific BIOS settings before updating the BIOS for an easier reconfiguration in the new BIOS version.

To update (flash) the BIOS, do the following:

1.Download a BIOS update utility program and its installation instructions from the Lenovo Support Web site. Then, make a bootable disc or a bootable USB key and print the TXT file that contains the installation instructions. See “Downloading the BIOS update utility program” on page 67.

2.Turn on the server and press the F1 key as soon as you see the logo screen to start the Setup Utility program. See “Starting the Setup Utility program” on page 55.

4.Press F10 to save settings and exit the Setup Utility program. Then, follow the installation instructions to update (flash) the BIOS using a disc or USB key.
