I was wondering about this since we have a machine that recently keeps
losing it config (after being turned on and off).  Only some of the
things would be wrong, e.g. amount of memory.  The professor has a
habit of turning the machine off because it's too noisy.  When running
EX CONFIG, the machine complains with a WARNING: battery bad or data
corrupted.  Also, the clock is usually behind in time.  I was hoping
that replacing the batteries (readily available?) would fix the problem.

Does this mean that there is something wrong with the machine besides
just a dead battery?  The CPU board was replaced some time ago when the
machine was hanging.  However, Apollo never did determine exactly the
cause.

I have swapped disk between machines.  It has never stopped the
machine from booting even without first running CHUVOL.  It warns
you in no uncertain terms that the ids are different and asks if
it should proceed.  It really thinks you should run CHUVOL first.
