Note
  • All BIOS update files for Intel® NUC products are available on Download Center.
  • Downgrading the BIOS to an earlier version is not recommended and might not be supported. An earlier version might not support the latest processors, bug fixes, critical security updates, or board revisions currently manufactured.
  • Do not interrupt the BIOS update process. We recommend the process be done in an environment with a steady power supply (preferably with UPS).
  • Before updating the BIOS, manually record all BIOS settings that you changed (from default) so you can restore them after completing the BIOS update.
  • All images in this example are for illustration purposes only. You need to select the correct BIOS files for your Intel® NUC.
