Booting a VAXstation 4000 VLC off the hobbyist boot CD-ROM

That command would be fine if DKA400: were a disk (or rather, if it were MKA400:) but for a disk saveset you need to specify the directory don't you: $ backup/image dka400:[000000]vms072.b/save dka0: /VERIFY I'm not sure that [000000] is right; I am sure, however, that omission of /VERIFY was just a careless oversight when copying the command :-) If you can now boot, try booting OpenVMS off the CD. This started to work with (IIRC) OpenVMS VAX V6.1 and is now quite possibly supported: B/R5:10000000 DKA400: (that's 1 followed by 7 zeroes). Apart from anything else, this will exercise your system considerably more than just booting SABACKUP. It's possible that the drivers just don't like your CDROM (although they seem to like it more than your previous one). If this still does not work, do you have access to a genuine RRD4x or even a SONY CDU-??? (many of the RRD4x drives were SONY CDUs of one sort or another - after a while DEC stopped *paying extra* to have the headphone socket torn out!!)
