In the event of difficulty with your MVME162P2 VME embedded
controller, try the simple troubleshooting steps on the following pages
before calling for help or sending the board back for repair. Some of the
procedures will return the board to the factory debugger environment. (The
board was tested under these conditions before it left the factory.) The self-
tests may not run in all user-customized environments.
