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, the Setup Utility program, and the TMM firmware. 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 57. The TMM firmware provides remote management features.
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/drivers. 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
“Updating the firmware” on page 82.
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 them. You can view the updated
information for the new BIOS version in the installation instructions for the BIOS update utility program.
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 are 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 record your specific BIOS settings before updating the BIOS for an easier reconfiguration in
the new BIOS version.
