It was all too simple. There'll be a day when you do not even have to think
using FreeBSD. :-)

No problems at all. Other than the fact that now the second card is
considered the first controller. So we had to move the connectors to the
new controller.
But the system is up and running:
ncr0:
1 Conner 1GB
2 XP34000 4Gb Quantums
1 4-16Gb Sony DAT
ncr1:
5 CD-roms.

Well This holds for any serious FreeBSD guru/hacker/friend:

See you soon.

Well that's no T1 connectivity, but you'll get around on the net:
Email/WWW/more and even UUCP.
4 hours free of charge, more fl 3,- /hour. (that's the catch :-))
