We have purchased/imaged several hundred Intel NUC D34010WYKH kits over the past two years. I put the 0033 bios on them, and image with Win 7.1 Pro. I am now seeing an occasional NUC that doesn't display our LAN as an option when hitting F10 at bootup. Funny thing is that the NUC does 'see' the LAN, since I can hit F12 and boot from our LAN that way. Also, if I let it boot up into Windows, I have no problem going to the internet. The sole issue seems to be that LAN just doesn't display from the F10 menu. Anyone else seeing this, or have an explanation?
