Yes; it selected and installed the correct kernel for SMP. I presume FreeBSD could do the same if someone put the energy into it. The only BSD I've seen that does SMP or UP with the same kernel is BSD/OS. They also had a wicked-fast SMP implementation with nearly linear scaling up to at least 4 processors. I don't know how the scaling went past that. To turn on SMP, you ran the "cpu" command with some specific flags. You could do this at any time once the system booted. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vivek Khera, Ph.D. Khera Communications, Inc.
