BIOS update (Intel Driver Support Assist not working)


Good day.  I've been having a difficult time with my NUC7i5BNH (product box is stamped with "NUC7i5BNH".  In computer System Information, System Summary, "NUC7i5BNB" is listed under "BaseBoard Product") .

For a few years now the Intel Driver Support Assistant hasn't seemed to work.  It will indicate a software update is available, a BIOS update to be exact but when I click on the "install" option and the computer goes through the entire process and reboots, the same message indicator is present and the option to install the same update remains available.  The Assistant although goes through the install process, does not install the BIOS update.  In years past I have phoned in to Intel support and they have either walked me through installing the process manually, or logged-in to my computer remotely and completed the update.  Attempting to do so earlier this morning I was told this was no longer an option for my model.

I would appreciate any help that would allow me to successfully update my NUC to the indicated firmware update (BNKBL357)

Hi @southTXNUC 

I believe I've a solution for you. Checked on my NUC and I confirm that BIOS update, using Intel DSA is not working. You can update your BIOS very easily, using express update method:

1. Download the latest BIOS file BNKBL357.86A.0085.EB.msi to your drive. 

2. Double click on the previously downloaded BIOS file, follow the instruction in the Command Prompt window (i.e, confirm by "Y" the update). 

3. Your NUC will reboot and the update will start automatically.

4. Once the update finishes, NUC will reboot to Windows.
