Yeah, the whole thing is pretty needlessly complicated - why they couldn't have it in there from the start or at least clearly mark P4s with x64, I don't know. I've looked on Intel's documentation archives and found certain Prescott CPUs that are supposed to support it, no mention of it being disabled, and I've been trying to get one of those, but they're difficult to come by, it seems...As far as a p4 with emt64, the 840 / EE / 840EE cpu's had that option. Problem is, I believe they were only made for value range laptops... EMT64 really didn,t start until the 6xx series on socket 775. I have heard rumors of it in certain Prescott cpus, turned off by Intel. I have no clue or if its even possible to re-enable.
