I picked up this Xeon Phi-based machine for a song. The problem is, as soon as I add a GPU to it, the board gets stuck on 90 - BIOS PCIe Enumeration when POSTing. It boots fine otherwise with no PCIe cards installed.
Per this review:

"Be forewarned if you are thinking about adding a GPU to the system, you will need to adjust the factory default BIOS settings. Options such as Above 4G encoding need to be changed to support modern GPUs. If you try this, and get a hang at DXE PCIe enumeration you know what went wrong."
I already have 4G encoding enabled, but what other settings need to be changed to get it to boot properly? And I've tried three different cards so far, each of them with 2GB of memory or less.
