Hi,
I just bought this board and was trying to boot legacy lan PXE to no avail.
I get:

Intel (R) boot agent XE (x550) V 2.4.19
Copyright (C) 1997-2017, Intel Corporation

PXE-EC8 !pxe structure was not found in UNDI driver code segment
PXE-M0F Exiting Intel Boot Agent.

Seems like some driver problem in Bios?
My system:

X399D8A-2T motherboard
AMD Threadripper TR 1920X
KSM26ED8/16HD
Any help is greatly appreciated
Cheers
mst
