I used your suggested boot command, but still got the same experience with the hang after the failed chdir's. I did try a whole sequence of things, though, based on your model: I eventually found a combination that worked: BOOT/R5:00000002 DKA300. I tried /R2:00000001, /R3:00000001, and /R4:00000001, which don't work, before hitting on this. Later, while doing some more scanning of my looks-pretty-complete ULTRIX docset, I learned that the correct command for single-user boot is: BOOT/R2 DKAxxx. BOOT/R3 DKAxxx is the multi-user boot string. I found this in the _Guide to System Shutdown and Startup_ section. I'll double check the /etc/fstab and modify it perhaps. In the end, though, looks like this system was setup with an extremely minimalist install of ULTRIX. There are a few commands in /bin, but almost every other useful tool is a slink to something on /usr, which itself is an NFS mount to some unknown box, long gone to me. I think I'll just install NetBSD (if I can get a larger drive!), use it as a MOP server to revive the other uVAXen, and finally get their disks imaged, which was the original goal. Of course, I do have a couple of Debian boxes that could serve the MOP stuff, but I'll still need to figure out what image I can use, probably a NetBSD. The only real trouble is that one or two of the other VAXen don't have ethernet installed. I do have a spare DEQNA, so I'll try that. Well, off to the lab! Super! I'll no doubt lean on you extensively when I get to that system. Gotta get these VAXen imaged first, then I'll work on that system. With it's DSSI drives, it should be interesting to get them imaged. Given that there's not a xBSD port for this system, I can only hope that there is a working ULTRIX set up on it. Thanks. Jared
