An older OS will not even know about multicore processor and will just boot off with the normal boot sequence. Currently, I am using FreeBSD 4.8 on Intel Pentium P4 with HT. It just works fine. Most SMP aware kernels actually probe the processor for multicore before actually booting off. Take a look at the spec document (slightly dated) at http://www.intel.com/design/pentium/datashts/242016.htm Hope this helps. thanks Saifi.
