Please me more specific. Provide actual part numbers, not descriptions! (descriptions are useless).

 

What memory SODIMM(s) do you have installed into this NUC?

What storage device(s) do you have installed into this NUC?

How does your current BIOS Configuration differ from the defaults (i.e. what have you changed)?

 

Use F2 to enter BIOS Setup (Visual BIOS) and then use F9 to set the BIOS Configuration to defaults. In the Boot parameters, verify that Legacy Boot is checked (enabled). Save this configuration and exit. After re-POST, use F10 to enter menu displaying list of bootable devices. Upload picture of this display (used paperclip icon to upload and then attach picture to response message

 

NOTE: Until a bootable image has been installed onto a device, the device may not show up in the display.

Hi,

 

In our society, NUCs are used as LTSP Client. the LTSP images are loaded from the LAN. so we need just PXE Boot on legacy device.

before with older versions of NUCs I did not have this problem.

but with the new NUCs that I bought, I can't boot from the network card,

the only difference between the old and new console is the BIOS version.

 

attached BIOS screenshots of new NUC and old One.

thank you for your help.

Hi,

 

we got the same problem with the NUC5CPYH Kit. The ones with newer BIOS versions can't boot with legacy LAN, only UEFI shows up.

Is there a way to get the old BIOS (no longer listed in the download section) and downgrade?

Honestly, I am trying to be positive here, but it is a fact: Legacy support is going the way of the Dodo bird. There are already a number of models of the NUC that have never supported Legacy boot and they never will. You do not need Legacy boot support to utilize PXE boot and you do not need Legacy boot support to utilize any modern version of Linux (including LTSP).

 

You folks can let me know what BIOS version you would need and I will check if a downgrade is possible. I rather doubt that this will be the case, but we can take a look. In my opinion, because of other issues that have been fixed in the BIOS, I consider downgrading, in general, to be a bad idea all around.

 

Sorry, reality bites yet again,

I'm aware of that but the current PXE boot server we are using for our Thin Clients only supports Legacy mode and there is no alternative at the moment.

The newer BIOS versions broke Legacy boot, so downgrading is the only option.

 

If possbile Version 57 or anything below that is ok.

Thank you very much.

Hi AlbertR,

yes, the problem still persists, with the NUC Bios version 0078.

I tried to downgrade the Bios framework but I still get an error message.

I upgraded my NUC5PGYH (has Pentium instead of Celeron and has eMMC that came with Windows 10 preinstalled - but board is identical and it utilizes the same BIOS) and I still had support for Legacy PXE boot after the upgrade. I talked to the NUC validation team. They were also unable to reproduce this issue; Legacy PXE boot remained available (even) after upgrading to BIOS 78.

 

I am not sure that you have done, but you shouldn't be seeing this happen unless there is BIOS corruption (or perhaps the LAN IC has failed?). My suggestion is that you attempt to reinstall BIOS 78, but this time do so using the jumper-based BIOS Recovery process. After BIOS Recovery completes, power on and use F2 to immediately go into BIOS Setup (Visual BIOS). Use F9 to restore the default BIOS configuration and then use F10 to save this configuration and exit. When the BIOS Splash screen again appears, again use F2 to re-enter BIOS Setup and then make whatever changes you need inthe configuration. Use F10 to save the changes and exit. When the BIOS Splash screen again appears, again use F2 to re-enter BIOS Setup. Check for Legacy PXE boot capability (it should be there).

 

Hope this helps,
