From my limited knowledge of SMP kernels, here's what you need to do: The SMP and APIC_IO options need to be in the kernel configuration, without a doubt. The other SMP-related settings are there to tweak the kernel in case you need other settings to support the hardware in question. You can rest nearly 100% assured that if a board is released for public consumption with two sockets, slots or whatever for processors, then it would have to adhere to some form of the Intel standard (if you're dealing with Intel processors). --- Andy To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
