Doesn't use DMA?! Maybe this card runs in the same way like the rme cards (rme32, rme96, rme9652, hdsp): In this case you copy data from/to the card and set a startbit on the register. After that you get an interrupt. You can read that details in the RME Digi96 document, which you can found on ftp.alsa-project.org. Those cards were alsa using a Xilinx FPGA and I think that they are in some way related to your Marian/Sek'd. (BTW: RME Digi32 was also sold by Sek'd!). I don't know the details about the pdplus driver, but maybe it's also interesting for you, because it can be related in some manner. The first step of writing a driver should be the pci detection without any driver functionality (study that manual "Writing an alsa driver" therefore or look at other pci driver code). And if you can modprobe/rmmod an empty module you can start implementing some functionality to it. martin ------------------------------------------------------- This SF.net email is sponsored by:Crypto Challenge is now open!
