The book you really want is Advanced 80386 Programming
Techniques. Unfortunately, it is out of print.
Fortunately, the author, Jim Turley, has expressed interest in getting the book on the web. That will be a somewhat long process, but at some point it should actually be available. When it is available, there will be a link to it in the annotated bibliography. In the meantime, you'll just have to browse your local bookstore for useful books on the subject.
