I think you are on the right lines here. Where does the resource come from? Are you going to support bus_space_map() and if so, how are you planning to call BUS_ALLOC_RESOURCE? I assume that you will update the alpha version of bus.h too. -- Doug Rabson Mail: d...@nlsystems.com Nonlinear Systems Ltd.
