I was thinking of an intel processor. i7 980x w 9GB RAM or yorktown HP w 8GB RAM and then installing XP SP3 Retail or, if windows 7 retail would work, windows 7 retail. but then I have a drivers problem if I retro xp - drivers may not be available for xp on the hp web site! http://www.forumcraze.com/forums/applications/34440-microsoft-windows-7-ult= imate-7600-16385-rtm-x86-retail-32bit-final.html what about the retail version of windows 7? it always treats intel procs as 32-bit doesn't it? or does it? I guess from this picture (correct me if I am wrong) the retail version treats all intel procs like 32-bit procs. can I set up an emulation product like freedos which has drive/ partition access to the rest of the system if I make another FAT32 filesystem? Freedos uses a variation of FAT32.
