Any tips/ideas/suggestions? TIA. Check the board manufacturers web site for a manual! Also notice that "An SMP kernel will ONLY run on an Intel MP spec. qualified motherboard" and "Be sure to disable 'cpu I386_CPU' && 'cpu I486_CPU' for SMP kernels." (The latter may not be required for your version, but won't hurt in any case). Also, check the stepping number of the P2's (on the chip, somewhere, one hopes, or possibly in dmesg when the system boots) and then check the intel web to make sure the two chips will work *together*. While each may work fine, if you've don't have compatible stepping numbers, they won't work together. <mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
