   Without seeing your setup, I can't tell you exactly why yours   
   results in DJA, but here is the relevant parts of the config I   
   used to do this exact thing. I don't remember exactly where   
   I got the base of my vax.ini, but it was one of the top   
   google results.   
      
   set rq0 rauser=8192   
   set rq1 rauser=8192   
   ### I suspect this is the bit you might be missing?   
    Configure a CD-ROM drive (RRD40) on disk interface RQ3   
   set rq3 cdrom   
   attach RQ0 /home/sthomas/vax/oldvax/data/rq0-big.dsk   
   attach RQ1 /home/sthomas/vax/oldvax/data/rq1.dsk   
   attach RQ3 -r /home/sthomas/vax/oldvax/iso/VMS55.iso   
      
   Cheers,
