You could always become an Intel Developer (free) and they will send you
the documentation in nice book form. I dont recall the phone number off
hand but you are looking for the "Intel Architecture Software Developer's
Manual" and associated data books/sheets. Its all free, all you need to do
is call their tech-pubs people. I suggest starting at say
developer.intel.com and digging around.
