Conforming Segments Attributes

These attributes specify whether a code segment is a conforming segment:

CONFORMING

The segment is conforming.
NONCONFORMING
The segment is nonconforming (default).

The concept of a conforming segment has to do with privilege level (the range of instructions that the process can execute). Conforming attributes are relevant only when you are writing device driver and system-level code. A conforming segment can be called from either Ring 2 or Ring 3, and the segment executes at the privilege level of the caller.
