Latest IntelMausi is 1.0.3 as far as I can see

That's what I have. Hmm... network is out under Big Sur but fine in Catalina.

IntelMausi 1.0.3 is what I'm using as well but then again that's on the Z270, haven't tried on the 390 yet.. not sure I will

@esafeddie graciously posted his EFI and booting from it solved my Network issue. So now it's going to be a bit of detective work to figure out why his works and mine doesn't!

I guess I know what I'm doing this weekend.

Thanks esafeddie! I love this community!

Edit: I found the culprit. In my rig, the Kernel > Quirks > DisableIoMapper needs to be set to YES. Network back on!
