I > am puzzled with your boot command. It's SIMH. Ooops. Didn't realise I wasn't clear that it was virtual. OK. Somewhere there was mention of VAX-11/780... I know the real H/W. I have never bothered with SimH. Ah. I do think the problem lies with not having a bootblack on dual. Not really. If you restore the correct saveset (.B), you'll get the bootblock and other stuff setup correctly as a part of the procedure. Find the right saveset. .A is not it. Johnny
