The most boards use the latter method while pontis board uses the former. In the latter case, the address is usually 2 bit, so you can do a wild guess more easily. > Reading the envy24ht-specs didn't help me, yet. > > One more question: Should I merge my code into pontis.c, which would blow it a > bit up, but would avoid duplicate code, or should I open a new > prodigy_hifi.c/h? Depends. Send us a patch, and let's decide this later. Takashi ------------------------------------------------------------------------- Take Surveys. Earn Cash.
