> By 2005 I expect 90% of new PCs sold were already 64 bit ready. You're several years off: "The FIRST processor to implement Intel 64 was the multi-socket processor Xeon code-named Nocona in June 2004. In contrast, the initial Prescott chips (February 2004) did not enable this feature." "The first Intel mobile processor implementing Intel 64 is the Merom version of the Core 2 processor, which was released on July 27, 2006. None of Intel's earlier notebook CPUs (Core Duo, Pentium M, Celeron M, Mobile Pentium 4) implement Intel 64." https://en.wikipedia.org/wiki/X86-64#Intel_64 https://en.wikipedia.org/wiki/X86-64#Intel_64 "2012: Intel themselves are limiting the functionality of the Cedar-Trail Atom CPUs to 32bit only" https://forums.tomshardware.com/threads/no-emt64-on-intel-atom-n2600.204215/post-2883539 https://forums.tomshardware.com/threads/no-emt64-on-intel-at...
