It reports what the BIOS tells the Linux kernel. You need to boot into
the BIOS setup screens and check the configuration there *before* Linux
boots. top will tell you how many CPUs your system sees. At the top
you 'll see 1 line per CPU. I can 't remember off the top of my head if
/proc/cpuinfo shows you as well. I would assume it does.
