I've a couple of questions after reading this thread ( ) that I hope that someone (ideally an Intel official) would answer:
1) Does the BIOS 0037 break Ethernet under Windows? (that other post seems to be about a Linux-related problem).
2) Which is the safest way to update the BIOS? Is it true that using the Windows app may brick your NUC, or it's merely an urban legend?
This was reported by at least one individual. All I can say is that it didn't break Ethernet or Wireless on my NUC7CJY when I updated it (this is same NUC board (but Celeron SOC instead of Pentium SOC) and shares same BIOS). The Intel internal validation team was similarly unable to reproduce this issue with either the NUC7CJY or the NUC7PJY.
I *have* seen the EBU updates cause problems. Your best bet is to stick with the standard F7 method. That is, place the .BIO file onto a USB flash disk (formatted on Windows-based PC using FAT32 file system and with the Quick option disabled) and insert this USB flash disk into port on NUC. At boot time, when splash screen appears, press F7 and use resulting dialog to select the .BIO file to be installed.
Hope this helps,
