Hi Dave, thanks for the reply.
About the rings I was using this reference from "OS/2 Architecture - A Programmer's Overview (Scott E. Garfinkle, 2000)"
It says:
"Ring 0: Kernel, Device Drivers, Filesystems
Ring 1: Not used
Ring 2: "IOPL" -- mostly print and video
Ring 3: Everything else"
That's why I was drawing it that way.
