  Somewhere around the shift from P3 to P4, Intel announced that it was
dropping multi-processor capability from its regular-line porcessors.  If
you want multiple P4 CPUs, they *must* be Xeons.

  Oddly enough, about the same time, AMD was re-introducing this capability
to its line, which it had let lapse some years earlier....
