He has videos on this driver running on NT and 2000.
A basic driver to link the NT disk device interface to the UEFI interface shouldn't be too hard I assume.
Easier would probably be running something like a single guest hypervisor that would essentially translate the storage (and NICs) into an interface the OS understood.
My immediate question which isn't (I think) answered in the repo is how do you interface the NVMe? Can you put NVMe on PCI as opposed to PCIe? How?
In the meantime, I'll just add the desire to do this to the other Alpha-related intrusive thoughts I have, like getting that port of OpenSolaris/Illumos to Alpha to run...
PCI to PCIe adapter and then PCIe to M.2: https://www.vogons.org/viewtopic.php?t=78987 (PCIe has some level of backwards compatibility, although like that thread shows there are some limits as to what will work).

I guess the same can be said about the OS itself :)
