I have tried this now but can't get it to work. Hopefully I'm missing something.
I have connected the m.2 expansion-card to the PCIeX4 slot and have nothing in the PCIeX1 slots. The m.2 drive is installed on the expansion-card (Samsung 850 Evo).
Note, Im not trying to run Windows on this drive, it's only for storage. However the drive isn't showing in Windows. I have updated BIOS to the latest version even though it did not mention anything about m.2 drives. I have tried changing the speed on the PCIeX4 slot in BIOS but it's the same on all options.
Anone able to point me in the right direction?
