I have a Dell Dell 7HYY4 m.2 card mounted in a riser card, 08XK04, in Riser 1 slot. Indicated in item 20 (https://i.imgur.com/qGfIBNm.png). Currently have 1 CPU , a 6138 Gold with a second on the way.

Neither M.2 drive I have installed on the card are recognized by the bios or my OS, in this case I am running Unraid.
