Updating or recovering the BIOS

This topic provides instructions on how to update the BIOS and how to recover from a POST and BIOS
update failure.

System programs are the basic layer of software built into your server. System programs include the POST,
the UEFI BIOS, and the Setup Utility program. The POST is a set of tests and procedures that are performed
each time you turn on your server. The UEFI BIOS is a layer of software that translates instructions from
other layers of software into electrical signals that the server hardware can execute. You can use the
Setup Utility program to view or change the configuration settings of your server. See “Using the Setup
Utility program” on page 39.

Lenovo might make changes and enhancements to the BIOS and TMM firmware. When updates are released,
they are available for download on the Lenovo Web site at http://www.lenovo.com/support. You can update
the server firmware by downloading an update package and following the instructions on the Web page.

You also can use the Firmware Updater program to help you keep the server firmware up-to-date. See
“Server setup procedure” on page 5.

Updating (flashing) the BIOS

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

Notes:

• 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 them. You can view the updated
information for the new BIOS version in the installation instructions for the BIOS update utility program.

• 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.

• If the power to your server is interrupted while the POST and BIOS are being updated, your server might

not restart properly. Ensure that you perform the BIOS update procedure in an environment with a
steady power supply. Besides, ensure that your server can restart successfully without encountering
hardware problems.

• 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.

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

1. Go to http://www.lenovo.com/drivers and follow the instructions on the Web page to locate the BIOS

update package.

2. Download the BIOS update package and the TXT file that contains installation instructions.
