  Use the PROM monitor's 'single' command.

  For machines earlier than 4D35s, whose PROMs don't have that command,
  say 'boot dksc(0,1,0)unix initstate=s'. Replace 'dksc(0,1,0)' with
  the appropriate device and partition if your boot volume is something
  other than a SCSI device partitioned in the standard manner; see the
  chapter on the PROM monitor in the "Advanced Site and Server
  Administration Guide".
