Let me understand though, are you collecting the boards for delivery to cameron, or you plan to do the testing yourself ? In the former case, people (especially from europe) might prefer to send cards directly to cameron... Speaking of chipset and support: i would try to prioritise work as some of the chips listed are so old that supporting them is practically useless. > cs4231 no no yes the 4231 is only a codec, i think it lacks the ISA interface chip which is different on different cards and needs special initialization in some cases. > opti925 no no yes > opti931 no no yes i have the data sheets for the 931 and probably 925, they are ps/pdf files sio i can mail them to cameron. > yamaha ymf711 no yes ? > yamaha ymf715 no yes ? > yamaha ymf719 no no ? the 711 and 715 are supported in the old "pcm" driver -- apart from a couple of register writes to set the mixer volume, it is a fairly good emulation of the 4232 so it works well. The 719 is undocumented andunfortunately some of the undocumented pieces refer to the control of the mixer. cheers luigi -----------------------------------+------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
