What about the invisible registers? Just now I learned that MMU registers, Interrupt Descriptor Table (IDT) uses these invisible registers. I'm learning these things in the hard way. Is there any resource (book/documentation/etc) that gives me the complete picture at once?

I am aware of the programmer visible registers and comfortable in programming with them. I just want to learn about invisible registers and their functionality. I want to get a complete picture. Where can I get this info?
