Unknown devices

[Arkady Tokaev]

Grate thanks!I had installed from 3 CD FreeBSD 7.2 with default (I hope) options.I don't understand - why it occurs, but now I understand - where to look.I think - I will reinstall the system, but if You have idea about this trouble - say me.Unfortunately I can not ask your last question because I very novice in FreeBSD. I just followed the instruction for FreeBSD router.  

Once more thanks,
Arkady Tokaev
