Hi
 
 
It is all in the FreeBSD = handbook.
 
You need to cvsup your source, and do a = make=20 world.  Then compile a new 4.2 kernel.

You can load that kernel, but it will not = work. =20 Basically you can't do
that.  In = FreeBSD, the=20 kernel is tightly integrated with the rest, and

        If you = have=20 compiled something into your 4.1 kernel that you want, =
then you'll have to put that into a new kernel config file = for 4.2 and=20
recompile your kernel, if you want to use = 4.2=20
