I've had an i3 nuc since its initial release and it has been working great - I should have stopped while I was ahead but... I currently am running BIOS 036 on the DC33217IYE and attempted to update to the latest version 48. After failures in windows installs I switched to F7 installs and as it turns out any BIOS install including the version I am currently running fails at the exact same place with the exact same error - fwupdatefullbuffer. My attempts to upgrade with recovery mode have also failed - any suggestions on how to approach this? I was planning to upgrade to windows 8.1.
So I managed to get myself through this - Using recovery mode I went back to Bios 32, then still using recovery mode I went 32-40, 40-46 and 46-48. Maybe I didn't need all those steps but at least I'm up to current rev.
