TempleOS has two main features. Ring-0-only and no paging. (It's identity mapped because long mode requires it.)

Linux and Windows have ring 3 and paging.

That's great, but I think it's mainly because TempleOS has different target use cases to other modern OSs.

How can long mode require identity mapping? Do you mean for ring 0 code?

For some reason I always thought templeOS was real mode.
