I have not spent much time looking for it yet, because I have not started on the drivers yet. The only driver I have started on was the MUX driver, and I was unable to locate documenation so far, but I have not given up yet. > I have problems with my spare time, but I am also interested in writing > drivers (especially for my machine !) > Which drivers will you write ? > MUX ?, SCSI ? (parallel port ?) I have a bunch of cards, so pick one that you want to work on, and I can start on a different one. I've been working on the MUX lately, but with your PDC patch, I'm kinda leaning towards the skunk or wizard scsi card. I have a stack of cards that to work on, so feel free to grab the one that suits your fancy :) - Ryan > Bye > Christoph > > > > Ryan Bradetich wrote: > > > > Hello Christoph, > > > > I have integrated your patch into my tree, and have been testing out the > > patch on my C200+ and the K460.
