The mobo chipsets on mATX do not (typically) support discrete & chipset
graphics together.
For example the intel Hnn chipsets (where nn==67,77 etc) do not support
mobo chipset GPU & discrete concurrently.

You can set the BIOS graphics device boot priority.

When you say PCI do you mean PCIexpress?
