Now I see it (I am new to this forum 😀). I will test and see if any of the options change the way the system POST's.
No the card is not fawlty. It works great when the computer has booted up. When installing the card in the G5 slot I have fast POST (5-10 sec). It's only when it's in the G3 slot. The card is PCIe x4 (gen 2) Decklink mini 4K. Installing any other PCIe cards in the G3 slot dos the same slow POST.
