I want to give you an example to let you know more.

I have a ASRock AD2550B-ITX board[1],
When another discrete video card is mounted into it mini PCIe slot or PCI slot,
The IGD cannot be the primary display adapter anymore. The display is totally black.
I have try to draft a few trivial patch to help fix this[2].

And I want to use the IGD as primary, does this count as an issue?
