BIOS Recovery Update Instructions

In the unlikely event that a BIOS update is interrupted, it is possible the BIOS may be left in an unusable state. The

recovery process requires the chassis to be opened to move the onboard BIOS Configuration Jumper.

Important Notes:

 Update the BIOS on your computer only if the newer BIOS version specifically solves a problem you have.

We do not recommend BIOS updates for computers that do not need it. You can view all BIOS changes in

the Release Notes included on the BIOS download page in Download Center.

 Downgrading the BIOS to an earlier version is not recommended and may not be supported. An earlier

BIOS version may not contain the support for the latest processors, bug fixes, critical security updates, or

support the latest board revisions currently being manufactured.

 Before initiating a BIOS update, be sure to read and precisely follow the instructions included in this

document. You may wish to print the instructions for easy reference.

 If a BIOS update process is interrupted, your computer may not function properly. 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 have been changed (from default) so they

can be restored after completing the BIOS update.

 All images in this example for illustration purposes only. You need to select the correct BIOS files for your

Intel NUC.

All BIOS update files for Intel® NUC products are available on Intel's Download Center at

http://downloadcenter.intel.com/.

WARNING: This process is intended to be performed by a trained technician.

1. Download the Recovery BIOS (.BIO) file. Example:

2. Copy the recovery file (*.BIO) to a USB device.

3. Plug the device into a USB port of the target computer.

4. Shut down the computer and unplug the AC power adapter.

5. Open the chassis and remove the BIOS Configuration Jumper. See the Technical Product Specification for

details including the location of this jumper.
