It sounds reasonable for me to remove old devices from GENERIC. But may I ask a question? If removed, how can I use those device drivers ? Do I need to re-compile kernel ? Or, can I use one of them with kldload ? Is it automatically loaded during the boot process, with charm in /boot/loader.conf ? I personally runs fxp and dc on my home pc, so I am very curious. Thank you very much.
