But my question was how do I get hold of the map of the internal parameters on the card mapped to the memory? Meaning what do each of the bit fields in the fxp_cb_config mean? Does Intel make such information public and what is procedure to get this information from vendors? I guess you are the best person to answer such questions. :-) Vinay -- Vinay Bannai E-mail: vinay@agni.nuko.com (408)-526-0280 x 275 (Work) http://agni.nuko.com/~vinay
