I have it working now. took me (quite) some time to find working numbers for port and irq. I tried guessing them using info from aux/pcmcia, /dev/irqalloc and /dev/ioalloc, I suppose I'm not smart at this. Is there a better way? I choose the first default configuration from aux/pcmcia -- naive question alert :-) just curious: Are there in general reasons to favor one over the other? (I attach the output of aux/pcmcia at the end) Somehow this worked more automatic on the bitsy, I recall. Is life easier on the bitsy wrt automatic choosing irq's? Or has more effort (default irq's) been put in for the bitsy? (I know/think more effort has been put in there wrt the possibility of sending a configure command to - what was it? - pcm?ctl ?) Rephrased/Related: just curious: are there intrincic differences between the bitsy and the pc that make things easier in one place and harder in another? For sake of completeness, for my laptop the following (inserted at the right place in sdata.c) made it work. I really have no idea how generally useful the irq is. if(channel == -1) { isa.port = 0x200; /* toshiba tecra 8000 */ isa.irq = 10; /* toshiba tecra 8000 */ channel = pcmspecial("MK5002MPL", &isa); } Axel.
