Has anyone tried to run 64 bit on one of these? I have since early 06 with fairly good results. However, the dell drivers which once worked with the trial versions of XP 64 failed when I recently installed the final build. It is an intel 945 P system board with integrated eithernet, and everything works great (and very fast) but the ethernet and PCI modem (which I don't use). Anyone have any experience? Thanks
