Hello! I just finished a new PC build and am only seeing 2 of the 3 m.2 NVMe drives I installed showing in the BIOS. One of them is in the main motherboard slot, and the other 2 are connected using the DIMM.2 expander card.
I have a GeForce RTX 2080 Ti in the PCI 16x slot. Otherwise, nothing else.
How can I troubleshoot this?
Two of the drives are Samsung 980, another is a Samsung 970.
