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 TSM 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 51. The TSM firmware provides remote management features.
Lenovo might make changes and enhancements to the BIOS and TSM firmware. 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.
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 support 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 correctly. 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.
To update (flash) the BIOS, do the following:
1. Go to 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.
3. Print the TXT file and follow the instructions to update (flash) the BIOS.
4. Check and reconfigure the BIOS settings for your specific needs based on your note or refer to “Using
the Setup Utility program” on page 51 after the BIOS update process is completed.
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 procedures to recover from the BIOS update failure.
Note: If the operating system of your server is installed under EFI mode, you must reinstall the operating
system after recovering the BIOS.
To recover from a BIOS update failure, do one of the following:
• Using the automatic recovery feature
1. Reconnect the server to an ac power source.
2. After the system health LED turns off, press the power button to turn on the server. The server is
turned on and then turned off automatically. Then, the recovery process starts. The recovery process
lasts about four minutes. After the recovery process is completed, the server starts automatically.
3. Check and configure the BIOS settings for your specific needs. See “Using the Setup Utility
