I want to update my BIOS but my NUC model is not explicitly listed on the downloads site.
I found update BNKBL357.86A and this appears to be the right one. However, the description does not list my model explicitly:
"This download record provides options for updating the BIOS of Intel® NUC Kit NUC7i7BNH, NUC7i5BNH, NUC7i5BNK, NUC7i3BNH, and NUC7i3BNK. You only need to download one."
Is this the right BIOS update?
How many letters/digits of the model number are important to determine appropriate drivers etc? (E.g. Is NUC7i5BN enough to search on?)
That is the correct BIOS.
There's around 10 models that BIOS works for so hard to list them all in the title.
If you scroll to the bottom of the page all the models are listed.
NUC7i5BNB is actually the identification string for the *board* that is used in this set of NUC models. Since all of these models share this board and thus share a BIOS, you can choose any one of them and it will (eventually) take you to the same BIOS download file.
