Burn IPXE on Intel NUC D54250WYKH2 (80861559.efirom)

[HLFH]

Hi,

I followed this to build my 80861559.efirom, related to my Intel® Ethernet Connection I218-V card that seems to be integrated on my motherboard. In fact, I preferred at the end to use rom-o-matic to build it because I didn't get any issues with it. At the end, I followed the Intel IPXE doc and used Rufus to burn the specific dosboot.img to my USB key.

Is that right I can't burn 80861559.efirom to my Ethernet card with bootutil -nic 1 -restoreimage -file 80861559.efirom and that I need to mod my UEFI/BIOS to integrate IPXE on it?

Because when I did bootutil -e and pressed on TAB key, I didn't see any 80861559.efirom, but something like 808615..EFI and I couldn't anything with that file.

So, I'm asking if I have to use UEFI Bios Updater to mod my BIOS.

But I don't know how to use it...

Is chainloading finally the only way for my Intel NUC to use IPXE??

And I really don't know how to get a modded BIOS with an IPXE Option ROM instead of the classic LAN/PXE Option Rom. I really prefer IPXE. I have an Intel Visual BIOS FYI.

Any ideas?

Should I do with MMTool (I really don't know) and how? I'm lost.

Thanks in advance,
HLFH
