I have an asus prime z270-p MB running OMV. It works normally until I install a PCIE controller. I have tried 3 different makes and all do the same thing. If I install the card and boot the system comes up as it should with one exception. The on board network card does not load. I am a bit new to this one so please be patient. I have tried a all of the slots as well. I know some slots have different addresses . Any Ideas on what to try..? One of the cards had the following chip set.
