Last week I went to intel's development site and "ordered" (I put it in quotes because it's free) the 4 IA-32 architecture books, and today they came via UPS ground. I wasn't sure they would come, or if they did how long I would have to wait, but I was pleasantly surprised.
Anyone else who want to buy them, go to http://developer.intel.com/design/pentium4/manuals/index2.htm and click on the first book you want, then go back and click on the next one you want until you've done all the ones you want. Then click "Process this request", and enter all the fields like any other ecommerce form. Except this one doesn't ask for any credit card information

Enjoy!
