The outstanding issues are that you can put more than two P6's in a single system, and that the L2 cache on the P6 runs at full speed. The 350 and 400MHz PII parts address the second issue, but not the first; if you are building a quad you really have no choice AFAIK. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
