Its not all hardware, only the ones that change to the "picture in picture" type of boot display. What happens is that both on the notebook (Realtek NIC) and the intel board (Intel NIC) DB75EN, when you choose to do the PXE boot, it uses some different type of display. I'm guessing the PE doesn't support whatever mode this is and the screen ends up going dark. The boot/loading screen does show up. I noticed there were no pics online to explain this, so I had to take some. Using the boot menu, I can choose IP4 option (and a cool thing is if booting to that fails, you get kicked back to the menu instead of the board trying to boot to the next device) Intel boot menu by Tripredacus, on Flickr These UEFI PXE ROMs change things where instead of displaying F12 as an option, it says press Enter. This "F12" screen is the first screen showing this different video mode. UEFI PXE boot F12 screen by Tripredacus, on Flickr And here you can see what happens after I press Enter.

Either you see this last screen but with just a black box inside, OR you just have a totally black screen. NOTE: UEFI boot from CD/DVD is not an issue. Also a previous product, a CZC tablet, that also could do UEFI PXE boot, did not display this behaviour. EDIT: I wanted to note that the successful CZC tablet PXE boot was done to Server 2012 RC, not RTM.
