It looks like the BIOS update that I installed previously was the correct one, but for some reason there must have been a glitch during the install which caused problems.
Fresh down load, fresh update and I'm a happy camper. Once again Scott, thanks for the reply ...
However, it would have been helpful if there was an explanation on the Intel website that the NUC5PPYB uses the same BIOS as the NUC5PPYH (amongst others).
While Intel sells a few on the NUC boards as standalone products, most have the board mounted in a chassis. Intel has chosen to provide branding information (name, serial number, etc.) for the board but not the system. They argue that they are kits, not systems, so this is all that is necessary. I disagree. Since the missing components (RAM, drives) have no bearing on the content of the branding, they could do system-level branding. Because they don't, however, this causes confusion because all that can be displayed is the board-level branding information.
Once again, many thank you for your replies, however, I think my final point is still a valid one.
Checking the Intel website ... http://www.intel.com/content/www/us/en/support/boards-and-kits/000005636.html
... the hyperlink clearly states, Boards and Kits, but yet there is no reference to the NUC5PPYB.
Regardless of how Intel chose to categorise their products, failing to list the NUC5PPYB seems like an omission to me ...

Thank you for contacting the Intel community.
The board is not listed on the Intel® NUC Boards website, but the Intel® NUC5PPYB is the board for the Intel® NUC Kit NUC5PPYH, so if you update the BIOS using the board model you are fine.
I’m sorry for any misunderstood.
