I was unclear in my last post. I'm downloading ISOS, then using ISORecorder
to burn the exact image to CD. I'm doing this on a Windows PC and ISOS of
NetBSD and other operating systems I burn in this way successfully boot on
other platforms.

But when I boot them on a VAXstation-4000/90A
   ....  Here's a console log of exactly what happens....
