ASTDEL indicates that something in the OS caused a machine 
check interrupt.  Does DECW$CONFIG mean it is the DecWindows 
config process that bombed?  Can you get the OS to boot in 
non-windows mode, and try to log in from a serial terminal?  
If DecWindows is blowing up, it could be that the graphics 
adapter has a problem, is set to the wrong address, or is a 
different type than the software is expecting.  You might 
unplug and reseat all mezzanine boards and cycle all DIP 
switches to make sure it is not just a bad connection.
