Aha!

I moved the other drive into the other, working system, copied the installation
image to /, put the drive back, booted and successfully installed NetBSD. Joy!

The problem I'm having now is with speed. NetBSD on this DECstation 5000/33 w/
40M of RAM is slower than my DECstation 5000/25 w/ 16M of RAM running Ultrix
4.3! Is this normal?

Thanks
