Hello Alexis, the NUC behaves that way by design, when there is no monitor connected. It is the same as having the monitor connected remotely to the NUC. Intel® NUC Boards and Kits — Remote access to Intel® NUCs
I am very surprised by your answer: if the NUC behaves that way by design, it means it can't be used for embedded systems that need to start without screen and keyboard. It is very common to use small fanless Atom PCs as small embedded machines, and embedded machines need to be able to start without any screen/keyboard plugged in.
When I purchased the NUC Atom, I didn't imagine that I would face such an issue, because I didn't have this issue with a NUC Celeron. If there are no other solution, I'll stop buying NUC Atom when I need a small embedded system (although it was a very good option with the 4 GB integrated flash and its fanless design). But I hope that Intel will fix this issue via a BIOS update...
Hello Alexis Hello Sylvia,
I didn't understand this kind of feature either. I don't have this problem because I evaluate the nuc as a thinclient.
Sylvia can you explain why this kind of feature so a can understand it.
I found this discussion looking for a solution to the exact same problem.
My recently bought Intel NUC 3815 do not boot if no screen is connected to it when using late BIOS.
The installed OS is Debian Jessie amd64 with no desktop environment.
The explanation and solution given by Sylvia do not solve the problem as I assume it occurs before the OS (and so the VGA driver) could be loaded.
I had this issue after updating the BIOS to the 0041 version of December 2014.
Furthermore, the NUC boots and works perfectly with no screen (neither keyboard nor mouse) when the original March 2014 BIOS 0014 is used back.
I can then control it with SSH perfectly en even VNC after installing Xorg and x11vnc server.
I did not try other version of the BIOS.
I hope that Intel will find a solution as I purchased this model to make a small server managed remotely.
Thanks for your message François. It proves that this issue of NUC Atom that doesn't boot without screen is a bug in the BIOS and it proves that it is not fixed in the latest firmware 0041 ! I can't believe that such a bug still exists in a BIOS from Intel !
It's very interesting to know that the BIOS 0014 works fine without screen. But we can't download that version from the Intel website ; the oldest BIOS available for download is 0019.
We still don't have a BIOS from Intel that fixes the bug on boot without screen, it's really a shame :-(
François, could you post somewhere the BIOS 0014 ? It's not available on Intel's website. Or could you try with the BIOS 0019 (the oldest BIOS version available on Intel's website) to tell us if the bug is present or not ? I don't have a NUC Atom any more to test, but I need to decide if I continue to buy some for my next projects or if I switch to something else.
Guys, I already requested the engineering team to upload BIOS version 014 to the Download Center, while we work on a solution for this headless issue.

Quick clarification, BIOS 14 was never posted externally to Intel Download Center. It was loaded on some pre-production systems but never intended for retail products going into the regular market and we (Intel) cannot make it public due to obvious reasons (fixes not included in BIOS)
I was aware of issues such as this one but on other systems and they were not related to BIOS but to the Graphics Driver on Windows (these issues were resolved with newer driver versions) but you are using Linux.
Have you tried a different Operating System by any chance? I am just trying to isolate the issue to BIOS or OS level.
Are you connecting a VGA monitor to make it boot? Have you heard VGA Dummy? This is a possible workaround.
No, I haven't tried with another OS ; I bought these Intel NUC Atom to run Linux Debian 7 (stable version). I have not tried with VGA Dummy. These NUC Atom are now used in production, so I don't have easy access to them.
The experience of François.Bl shows that this problem can be fixed in the BIOS. My experience shows that it doesn't affect all units, but a significant part of them (about half of them).
A new BIOS has been released : version 0044 dated July 1st.
Has anyone tried it to see if it fixes the "doesn't boot without screen" issue ?
I confirm that DE3815TYKHE BIOS version 0044 still doesn't work headless!
is there any fanless embeded intel machine that works headless for embeded applications?
or we soul'd start looking elsewhere?
no RzR nothing broke everything works great with BIOS version 0044 except headless boot :-)
I had to downgrade to v43 to fix those issues, do you know which version did you ran before flashing v44 ?
I suspect untested version jumps like :
I am making a list now :
