I've got a brand new NUC5i5RYH and I'm stuck at trying to get to the BIOS to enable it to boot something.
I've seen some others have similar problems but I thought I'll report my experience to add some data:
On the Display Port:
- using Dell's DP-mDP cable that came with the monitor
- nothing displayed
- the NUC does talk to the monitor enough for the monitor to react by going to sleep when the NUC is switched on
On the HDMI Port:
- using High Speed HDMI/HDMI cable full size connectors + HDMI adapter micro/mini/full Y adapter
- the PXE network boot console is shown in 640x480 about 2-3s after boot
- when pressing F2 after the keyboard numlock led switches on, I get no display (presumably being in the BIOS in 4k)
The funny thing is that I've seen the BIOS once. Problem is it didn't last and I can't reproduce it now as I don't know what exact sequence worked! I think it was on HDMI but not 100% sure. It was displayed in 4K -- tiny box (1024x768?) in the middle of the screen. I have no mouse at the moment and it apparently locked up before I could figure out keyboard navigation, and I crtl-alt-del and never saw it again.
I have not tried other monitors as the only one I have is an ancient DVI/VGA one, and I've got no DVI/HDMI solution.
I've tried to boot an Ubuntu USB install stick regardless, but that blinks the LED on the stick and gets stuck. (No legacy on USB? Video stuck as well?)
- 1x 4GB KVR16LS11 (on approved list)
- USB keyboard
- I've updated the BIOS using the USB stick + jumper trick yesterday which as far as I know worked (it blinked as speced and I think I saw the number that one time I saw the BIOS).
- is there a way to bypass the BIOS or to access it using the network? (trying to boot an Ubuntu USB install stick gets no display as well)
- I guess I could try to set up a PXE server for a diskless boot of an install but that seems a hassle, has someone tried that?
On the other threads, some people seems to have solved similar issues by trying other video cables. I've got some ordered, but I'm not impressed by Intel staffer replies like "we do not support adapters" or "try another cable". I'm just guessing, but what it looks like so far is fragile timing issue or something like that (hence my seeing the BIOS once?), maybe a combination of RAM and video link timing, where the hardware is too sensitive to a slightly non-optimal link. Instead of saying it's the users' problem to find perfect lab-condition hardware, why not put some engineers in a room with a box of adapters and cheap cables and get them to try to make the thing more robust?
If the new cables don't work, I need to know whether this could be a dud unit or it is a design fault (in the former case I need a replacement, in the latter case a refund and buy someone else's hardware).
