Sorry for the slow summary : we are testing for a good solution since **begining
of july** without success. Success come three days ago only. We configure
networker (the server) on a *K200* with a *HP* FDDI card and it's working.

Backup of the HP itself are good and dont crash system

Network managers tell me that our chips, versions, etc... are at the top level.
