I installed 1.4.1 from binaries on DS3100. 
I have two HDs rz0 (Ultrix) and rz2 (NetBSD) and a floppy (rz4).
All three are reported by PROM (test -c) and Ultrix but only 
rz0 and rz4 are reported by NetBSD. As a consequence mdir (mtools)
returns with the following message:

Can't open /dev/rz4c: Device not configured
Cannot initialize 'A:'

Do I need to setup GENERIC and rebuild the kernel? 
If yes, is it enough to download just syssrc.tgz, or more is needed?


I would appreciate very much your help!
