I'm relatively new to Intel x86 hardware as I am transitioning over from the MIPS world. I have searched around and found some basic info, but it is just enough information to get confusing. What would be really nice would be a nice book discussing this topic in detail, as opposed to a few data sheets and/or the occasional website that has only a brief paragraph. Thanks... -Jarrett Redd
