That is GENERIC with except that is has support mutiple CPUs

OR, you can do

echo "KERNCONF?=SMP" >> /etc/make.conf
make buildkernel
make installkernel

In 7.0+ its /etc/src.conf

If you ever compile a custom kernel you'd use that name instead.

Work like you don't need the money,
love like you'll never get hurt,
and dance like nobody's watching.
