Correct. System wants to auto-boot from DU0

Initially, pulled the RQDX1 from the last slot, and installed RQDX3 into
empty dual wide position (slot 3, right, seemed odd that it was empty.
 And yes, the system ran prior to this) next to tape controller. Later
reversed process.

Well... if this is indeed a 'can't talk to controller' error rather than a
'bad drive(format)' error, this is oss... At this point, except for the
drive all in the system is back as it was.
