Whoops, you're right. Ignore my previous post. From Configure.help: CONFIG_SMP This enables support for systems with more than one CPU. If you have a system with only one CPU, like most personal computers, say N. If you have a system with more than one CPU, say Y. If you say N here, the kernel will run on single and multiprocessor machines, but will use only one CPU of a multiprocessor machine. If you say Y here, the kernel will run on many, but not all, single machines. On a singleprocessor machine, the kernel will run faster if you say N here. Note the 'the kernel will run faster' part. Honestly, though, I don't think you'll notice. I was basing my answer on the option for using APIC on uniprocessor systems. Which is needed on SMP systems (IIRC), but not on uniproc systems.
