Hello,
Thank you very much developers for giving me such a nice OS
up-to-date.
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.
Best Regards,
