HP EliteDesk 705 G3 SFF

The same motherboard with add-on network cards does boot using PXE. 
It's an EFI board but Secureboot is currently disabled.

CentOS 6 + updates.  I've tried all the CentOS 6 kernels up to 2.6.32-
696.10.2.el6.x86_64

I've tried updating the tg3 driver from 3.137 to both 3.137h and
3.137o, with the same result.

I'm currently in the process of making 4.13.2 boot.
