We had a similar trouble here, only running System V R2.2 on a VAX 730.
The problem was not with switch settings, but was a trouble with the
physical drive. I think its call the maintenance folks time (sorry to say)

This message is quite correct. There is only switch settings for the csr,
not the vectore ( as in other old DEC products ). The csr HAS to be
correct otherwise the system wouldn't even get this far, and the vector
address is downloaded to the board.


By the way, we retired the VAX 730.
