The MVME7100 control registers are described in the MVME7100 Programmer’s Reference.Prior to installing PMC modules on the MVME7100 baseboard, ensure that all switches that are user configurable are set properly. To do this, refer to Figure2-3 or the board itself, for the location of specific switches and set the switches according to the following descriptions
