Re: One thing may be data files...
We have that. Write a memory contents file to whatever storage device you like, which can be optane, and restore it. In the older computers, it happened that that file was the only thing on the ROM chip and so you didn't have to use a filesystem to find it, but you can do the same with this if you want; have a partition at a specified offset and find it that way. If you want to use this as direct memory, that works too. The functionality to do that is already available and doesn't require but can use optane to accomplish the goal.
