That is one of it's true joys IMO.

Where 'on the web' - there are at least 100 web sites in existance
:-).  For definitive answers start with www.freebsd.org.

So those changes would have started with FreeBSD 3.2, though SMP
was in there before.  Whoever wrote that page that FreeBSD has
had SMP since 5.0 really doesn't know a damn thing about what they
are talking about.

The RELEASE NOTES [if you don't read those you really should]
you would see that 5.0 uses SMPng - SMP next generation.

You need to see if both CPUs are recognized - see your dmesg.

You need to make sure your BIOS has APIC enabled.

And you need to copy GENERIC to some name you give it, 
remove the #s from the front of the options lines
for SMP and APIC_IO and rebuild your kernel.

The Handbook is on your system if you installed it or 
at the www.freebsd.org - it will give you the details you need
to rebuild your kernel.
