Reply-To: ben@stuyts.nl X-Unexpected: The Spanish Inquisition Sender: owner-freebsd-smp@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk Hello, I'd like to add a second cpu to my current motherboard (a GA-586DX) and start playing with SMP. It now has a Pentium 166 MHz on it, and these are a bit hard to find now. 166 MMX's are no problem though. Is it possible to mix a standard Pentium with an MMX one? FreeBSD won't be using the MMX features anyway, I guess. (Or will it in the future? Maybe in the X server, or some kind of multimedia app? I guess having one std and one MMX cpu might be confusing then.) For that matter, can I put in a 200 MHz MMX, in the assumption that I will replace the old std 166 also with a 200 MHz MMX somewhere in the future? Need the two cpu's be of the same mask revision? Thanks, Ben
