Well, Installing OpenVMS on a VAXstation 4000/60 has taken me all afternoon on and off... I almost gave up. I kept getting 'medium has gone offline' errors with the first hard drive I tried, so I swapped it for another drive, same issue, thought the CDROM must be dodgy, swapped that out, same problem, eventually went back to the original hard drive (which was ZEN's page/swap drive, so easily recreated) and everything is fine. So that is *two* hard drives exhibiting the same problem. Bought from the same ebayer, they were original DEC drives. So sometimes perseverance does pay off. I was also getting a system board error to do with NVRAM, so I swapped out the TOY chip, still got the error first reboot, but after that it was fine. Mark.
