   This is just a guess, but I'd say it means you need to run the 
   reference disc again, so the system's configurations catch up with the 
   new memory you've installed.  This is your "setup-type" program, if you
   like.

   But I have not looked up this code, so I can't promise you don't have
   a genuine problem.
