Cannot boot with PXE on new Intel I217-LM nic card

Question

I imaged a new Dell 5540 with nic I-218LM perfectly by inserting the driver.
After that I did the same with the Lenovo T540p with nic I-217LM which is the same driver "E1D6232.inf" and when I boot into PXE (after changing bios to UEFI network to both or legacy) it finds the SCCM/WDS server and finds the advertisement.
It asks me to press F12, I press it but it doesn't react and the following line is: "PXE-MOF: Exiting Intel Boot Agent". So I find this weird, it's like the key F12 doesn't work. Is there a way to see if this key works?
Does anybody know why it's not going furthur? The correct driver seems to be injected into the boot image. I am using the driver from the lenovo website in the Windows OS after Winpe stage.

Answer 1

After much frustration trying to get the drivers to install for a winpe boot image I found that the issue was it couldn't find the files to copy.  The inf file does not tell the install where to find the driver files. Instead it was trying to find them
in x:\windows\inf\   not where they are installed in the pe image simple fix was to copy the files into the windows inf folder and now the drivers install correctly.
I found this by hitting shift-F10 and the running notepad and opened the x:\windows\inf\setupapi.dev.log file, the source path for the driver points to x:\windows\inf (see below)
\machine.inf_amd64_neutral_9e6bb86c3b39a3e9\machine.inf' ([strings])
