There is NO chipset that enables SMP. Opteron's are directly connected thru HyperTransport links. (AMD marketing now calls this Direct Connect(tm)). The various chipset pieces are only for I/O, not memory controller or MP communication. Note that the HP dual-processor workstation doesn't use the AMD chipset, yet is MP. (Opteron's also aren't SMP, but are a NUMA architecture) -- -- David (obrien@FreeBSD.org)
