Sure. cd to /sys/i386/conf, look at the config files there. You'll
want to make a copy of one and then edit in your changes. After that's
done, do the following:
config MYNEWKERNEL
cd /sys/compile/MYNEWKERNEL
make depend
make # this will take a while
Replace MYNEWKERNEL with whatever you named the kernel config file.
After you do those four steps, your new kernel is in
/sys/compile/MYNEWKERNEL/kernel. You still need to install it. What I
do is move the old kernel (mv /kernel /kernel.old) and copy the new
kernel into root (cp /sys/compile/MYNEWKERNEL/kernel /kernel). Reboot
your system to see the changes.
(There may be something I'm missing here, and this may not be the best
way to do it. It works for me.)
If for whatever reason your kernel doesn't boot correctly, you can
always load the old one by typing it's name at the boot prompt:
boot: sd(0,a)/kernel.old
Two important things to keep in mind: Always keep a known working
kernel in root, and always make a backup copy of the old config
file before you edit it.
It's not as tough as it sounds, the only tricky part is getting the
config right. After yu've done it a few hundred times, you'll be able
to do it in your sleep. :)
