BIOS Version Downgrade Instructions

Downgrading the computer BIOS can break features that are included with later BIOS versions. Intel recommends you only downgrade the BIOS to a previous version for one of these reasons:

  • You recently updated the BIOS and now have problems with the Intel® NUC. Examples: Computer does not boot, features no longer work.

  • You got a replacement Intel® NUC through warranty, that has a newer BIOS than what your company has standardized on.

The steps to downgrade a BIOS to an older version are the same as for upgrading to a newer version. You are prompted to confirm that you really want to downgrade the BIOS. Confirm that you want to downgrade, and continue the update process.

Since Intel® NUC products support the Intel® Management Engine (Intel® ME), BIOS downgrades are not recommended for security reasons. If a BIOS with Intel® ME must be downgraded, and the downgrade affects the Intel® ME version, the BIOS Recovery Update is the only method you can use.
