We have aquired 28 workstations that are "sparc" compatible.
We would like to upgrade to NetBSD, (which is already running
on alpha and decstations). 

The workstations are Solbourne Computer Workstation S4000DX
the boot rom is version 2.1.  The work stations are currently
running the old 4.3 Sun OS.  

We have tried installing NetBSD 1.1 for the sparc.  There are two
errors, first the default setup of the current workstations we can
not find /boot.  So we used the /boot from the distribution. Now the
error at boot time is "sd.si()/netbsd: conflicts with rom "

Any help would be apprecited, even a direction to search.  Machines
are currently running the old Sun OS much better to use the much
"superior" NetBSD.
