Downgrading the BIOS can break features and remove security patches that are included with the latest BIOS version. Intel doesn't recommend BIOS downgrades, but you might wish to do so 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.
The steps to downgrade a BIOS to an older version are the same as for upgrading to a newer version.
- Download the BIOS installer for the version needed from Download Center.
- If the version needed is not posted, contact Customer Support.
- Run the BIOS Update utility.
- Confirm that you want to downgrade.
- Continue with the downgrade process.
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.
See BIOS Update and Recovery Instructions for Intel® NUC for complete instructions.
