Ok, so I ran Snappy - and no option for an NVMe driver. Now, this whole thing makes me wonder. Intel Gfx Driver Windows 10. On my X99 platform - it is an ASUS motherboard, with an Intel chipset, and a Samsung 950 Pro. In my head, the driver for anything on the motherboard should be from Intel as part of the chipset - or available through ASUS if it is a third party vendor.

But no - the NVMe driver I got and used was from Samsung. Is the Samsung NVMe driver compatible with other M.2 SSD drives as long as they are NVMe and not SATA?

Jan 11, 2018 Update Windows 10 to 1709 on NVMe disc. Windows 10 IT Pro >Windows 10 Installation. Also install the latest intel chipset drivers from the intel website.
