Modules are loaded by the user adding entries to /boot/loader.conf.
That example will load the "sis" driver for the Silicon Image network
interfaces on my Soekris net4801 board as I have removed almost
everything in my kernel and just load the modules I require.
Some modules will automatically load when another driver requires them.
FreeBSD does not try to discover and reconfigure your hardware at boot
time like the "kudzu" utility in Linux.
Instead it will attach to the hardware for which you have drivers in
your kernel or for which you have told the loader to load modules for.
