Is the C606 chipset similar enough to the X79 to support NVMe booting? I’ve tried MMTool and inserted NvmExpressDxe_4 module but that didn’t seem to work, though I now have another boot device “PATA SM:” listed. Selecting it does nothing.
SSD is a Samsung EVO 970 on an NVMe to PCIe 4x adapter card. When booting from SATA SSD, NVMe is functioning normally in windows.
