Posted a reply to this a while back (check the archives).

After installation you just need to recompile the kernel (see the
freebsd handbook).

You just need to uncomment/enable these options in the GENERIC kernel
configuration like so:

#cpuI486_CPU
cpu I586_CPU
cpu I686_CPU

options SMP # Symmetric MultiProcessor Kernel
options APIC_IO # Symmetric (APIC) I/O

recompile and reboot:

#cat /var/run/dmesg.boot | grep SMP

should give you this message:

SMP: AP CPU #1 Launched!

If you're curious, you can run top. It will have a CPU column.

 Is *this* actually correct?
 
 Looks as if you've enabled two different CPU classes here in the kernel.

That's ok - it means that the kernel will run on both (i.e. less optimization).

SMP kernel installation

Hi,
For a multiprocessor machine,to install FreeBSD,is
something extra needs to be done from what will be
done to install the OS for a uni processor machine?I
mean is there anything different to be installed for a
symmetric multi processor machine?

thanks

Sorry after re-reading my reply one thing I did not make clear

Install freebsd as you would with a uniprocessor machine, then boot that
install and do what I recommend below

 - Mike

 
 You need to recompile the kernel with the SMP options turned on, install
 the kernel and reboot.  On a reasonable modern machine takes less than 10
 minutes.
 
 See /usr/src/sys/i386/conf/GENERIC and the FreeBSD Handbook.
