x86 Real mode programming & architecture q's

Hey i just have some questions and was wondering if anyone can help me out...

1) How do controllers actually get assigned to i/o ports? I've read that they have been hardwired but some devices allow you to do i/o steering? I take it its kind of like shadowing or am i wrong?

2) For some reason i can't think of the rest right now haha

But any books on computer hardware and low level programming will be helpful. Thanks in advanced =D
