Howdy; Thanks to Jeff Kaneko, who supplied the missing chassis parts, my VAXstation 4000/90 is all happy and ready to run. I had originally planned to install VMS 5.5-2 from a CD I'vfe had kicking around for ages (actually, from five years ago when I wanted to buy a VAXstation 3100 from Tim Shoppa), but booting the CD didn't seem successful. What do I need to do to install VMS on this machine? One of the drives in the 4000 has VMS 6.2 Standalone Backup installed, if it helps. The CD is labelled, "VMS V5.5-2 BIN CDROM Disc 1 of 1 October 1992". ok r.
