Updating the BIOS

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

Note

  • 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.

  • After you have updated the BIOS firmware, all the BIOS settings will be preserved. If you want to do any specific setting changes, please configure the BIOS settings.
