It appears in the FreeBSD Hardware Notes that Core > Duo is not compatible. If you read closely this only applies to the amd64 version of FreeBSD. It is because the original Core Duo doesn't support 64-bit mode required by FreeBSD-amd64. Note the Core Duo and Core 2 Duo are different CPUs. Evidently this has come up before: http://lists.freebsd.org/pipermail/freebsd-questions/2012-January/237144.html > If none of those processors are compatible, would a Core 2 Extreme > Quad Processor work?

Any Intel or AMD CPU made in the last 15+ years intended to run Windows will also run FreeBSD. Worst case, on some lower-spec CPUs, only the i386 version of FreeBSD will work, which restricts you to a maximum of 4 GB memory (among other things). In contrast, the amd64 version has practically no memory limit. Most modern CPUs made since 2006 will run both the i386 and amd64 version of FreeBSD. Regards Andrew
