What I'm more interested in is the code that the boot cpu uses to kick the other cpus and the code that the other cpus execute to initialize themselves once they've been kicked.

They are built into the ACPI table in your BIOS, so the OS "just finds them" when it reads the processor SMP table information from there. If you are installing a multicore CPU in a motherboard that's not expecting it, you will need to update your BIOS at the same time so that the processor is reported to the OS. -- Terryhome | help
