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.
• After updating the BIOS firmware, all of your previous BIOS settings will be automatically restored. 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.
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 55 after the BIOS update process is completed.
Recovering from a BIOS update failure
