I have the PCIe x4 card sitting in the x16 slot, which I think is fine by the PCIe standard. The drive does not show up in bios.
The adapter card states "Support ASUS Z170/H170/X99/Z97/H97/B85 series motherboard models" chipsets. As far as I can tell the motherboard is a P55.
Is there some way to use the NVMe card or do I need to replace the motherboard?
