[Simh] Question about special pidp8 simh and ADVENT

[B Degnan]

hi,
 To anyone who has a PiDP8 with OS/8 installed maybe you can advise what is 
causing ADVENT to not load.  I have all switches up, which I understand to 
be = 000
  
 My RK05 has two partitions like my actual RK05
  
 . R FRTS
 *RKB0:ADVENT.LD
 [esc]
  
 --rather than go into Adventure I get ---
  
  
 D.F. TOO BIG INIT   0000
 MAIN  1740
 .
  
 --I assume I need to update my ini file, or is there a front panel switch 
that I am misunderstanding?
  
 Thanks
  
 Bill
