I was finally able to make it configured. As I mentioned before I have two
HDs, rz0 (RZ57 with ultrix) and rz2 (ST32430N with netbsd).
If I power down my DS3100 and power it up again the floppy gets configured
(but only if RZ57 is on). If I do shutdown and boot, it doesn't. 
It seems to be a timing problem. The floppy needs more time to respond
correctly and that time is provided by RZ57 spinning up after powering it on
and booting the system. If I installed netbsd on RZ57 everything would
probably be fine.

Here is the PROM response (if it could help to fix the problem):

Thanks a lot for your help!
