Absolutely right idea. I thnk the DS2438 is the prefered configuration chip (It has many functions).

The first involves a DS2409 Hi. I've been pretty quiet on this list so far, so I feel a bit awkward jumping in right here. Anyways, I have another suggestion for identifying aggregates. You can put an EPROM device such as the DS2505 into each aggregate device and place information on that EPROM describing the components on that device. The device could contain a magic code to indicate it belongs to your system, then a device identifier to indicate which type of aggregate device it is (assuming you have more than one type) and finally a list of addresses of the individual devices that make up the aggregate device. The address of the DS2505 could be used to uniquely identify each aggregate device. In fact, if this became a frequent request, it might be possible to add a pluggable architecture into OWFS to handle these aggregates automagically when a DS2505 is detected with the magic word -- but I'm probably getting way ahead on this now. ttyl srw ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
