1. Go to your kernel configuration directory (e.g. /sys/i386/conf)
2. run "config CONFNAME" (e.g. config GENERIC)
3. chdir to the printed directory and follow the instructions about make
cleandepend;make depend;make; make install

(if you need to re-make the kernel with changes to existing files, you
can skip the make clean; make depend steps).
