System Controller Selection (J22)

The MVME2603/2604 is factory-configured as a VMEbus system
controller by jumper header J22. If you select the "automatic" system
controller function by placing a jumper on J22 pins 2 and 3, the
MVME2603/2604 determines whether it is the system controller by its
position on the bus. If the board is in the first slot from the left, it
configures itself as the system controller. If the MVME2603/2604 is not to
be system controller under any circumstances, place the jumper on J22
pins 1 and 2. When the board is functioning as system controller, the
LED is turned on.
