John, I'm not sure what happened or what you did that resulted in such grief. After my last repairs, the machine apparently has been running fine for some time. Your CONTEL man may not be intimate with RT-11, but there are lots and lots of ways to avoid massive volume transfers. Nevertheless, I left the machine in such a way that even that violence would not wipe out crucial data. I see that you apparently successfully rename bos10.wav and udp.sav. Why did you do that in the first place? If you could not reboot rt-11, I suspect the boot record on dl0 may be corrupted. That is pretty hard to do and can't be done in the fuzzware. the rt-11 command COPY/BOOT DL0:RT11FB.SYS DL0: should refresh the record and can be done from a floppy-based system, assuming the *.SYS files are okay. You cannot format DSDD floppies using the rt-11 FORMAT utility. There should be a special format program lurking on your disk or in the DSD (now Qualogy) service manual that comes with the disk drive. However, the easiest way to do that is to stop the machine, remove the drive front cover, switch to FORMAT with the selector switch, insert disk and press the red button. Reboot rt-11 when done and use the INIT DY0: command to initialize the directory. It is possible to create floppy backups of the fuzzware itself, which is found in the *.DSK files now on your hard disk. Use the rt-11 MOUNT command to mount these files as logical volumes and copy files as needed. The easiest way to create a complete archive is to use the rt-11 command COPY/DEV FUZZ1.DSK/FILE DY0: and so forth. If in fact your recent problem is a broken rt-11 bootstrap and in fact the fuzzware had been running okay, please rename the BOS10 and UDP files and reboot. The old versions cause some grief with companion time servers elsewhere in the Internet. Otherwise, please tell me more details and I will do what I can. By the way, the easiest way to duplicate formatted floppies is using the rt-11 copy command as above. Use the COPY/DEV DY0: x.DSK/FILE to create a floppy image on the hard disk (for some unique name x), then use the COPY/DEV x.DSK/FILE DY0: to copy the image on a fresh disk. Delete the file x when done, as the temporary file is about a megabyte long. Dave
