      GPU risers are not detected – only if GPU’s are plugged into them is anything detected.

        I was intrigued by this questions as I just built this exact system following Rolf’s post. I ordered a couple of M.2 PCIE adaptors to give it a shot. Unfortunately, while you can connect a GPU to the M.2 slot using the adaptor and during EthOS GPU Detection all 7 cards during. Unfortunately, I got a kernel panic just before EthOS Desktop actually loaded.

        I wonder if this is something ASRock and/or EthOS can fix with a firmware/ software update. Or if this is a permanent hardware limitation of the board. But M2 slots support PCIe so it should work. The board even shows one of the M2 slots at PCIe 5 under EthOS (when used in conjunction with 5 other PCIe slots). Normally with 6 RX580 connected to the PCIe slots on the board, they show up in EthOS as 1-4 and 6, 7.

        I will post this on IRC to see if anyone has any ideas/ experience with this.

          Sorry, rushed in editing…. * during EthOS GPU Detection all 7 cards are recognized and show up on the initial boot screen. But the system kernel panics and hangs just before loading the EthOS Desktop.
