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 47.
Lenovo might make changes and enhancements to the BIOS. When updates are released, they are available
for download on the Lenovo Web site at . 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 62.
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.
