(yes, it may take more mem, but if you have more than 128MB RAM, ignore it ;-) kernel compilation is usually done if you MISS something in GENERIC which is for example a specific piece of hw, loadable modules (kldload, loader.conf.local) are also a good choice avoiding kernel compilation. read your dmesg. all main drivers/systems loaded are listed here. take care for their parents/childs (a disk is attached to a bus which resides on a controller...) read the man pages for the drivers (man amr shows what it was written for if you don't know it) check the web for e.g. http://www.google.com/search?hl=en&lr=&q=freebsd+man+amr and read the doc's you can find. br...
