Solving Startup Problems

In the event of difficulty with your MVME240x VME Processor Module,
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 selftests may
not run in all user-customized environments.
