However, from reading around, there is only support in the AMD64 arm of FreeBSD-5. Since these are extensions, would I be able to use a pair of Xeons with EM64T and run FreeBSD-4.10 until such time as FreeBSD-5 becomes production ready (5.3?), or should I stick with straight Xeon/XeonMP? Thanks, Stewart.
