I unearthed a Solbourne S4000 (ROM 1.1B) running an ancient version
of SunOS.  I'd like to get NetBSD/sparc running on it.  However, it
seems as if this is not going to be an easy task.  I loaded the 15May
snapshot onto a spare DEC RZ26 and tried to boot off of it.  It complained
that the entry point overlapped the PROM and aborted the boot.

Looking through the NetBSD kernel sources my current guess is that my
efforts are doomed to failure.  

Any words of encouragement would be gratefully accepted...

Here's the output from dmesg when it boots SunOS...
