I've installed 4.x on an SMP athlon system. It worked great. The Athlon's use a APIC just like Intel systems, so the SMP MD code is the same. Our existing SMP code just works out of the box, whcih is why I said 3.x would probably work fine, too. > FAQ 3.31 is about SMP support.

The only SMP systems supported on 5.x but not 4.x are SMP Alpha systems (as in the alpha architecture). -- John Baldwin -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-doc" in the body of the message
