ISA DAQ board

Hi!

I have an ISA DAQ Board and so far there´s no COMEDI driver available. I want 
to use the board with RTLinux.

- Is there a chance that my card could work wit Comedi´s standard ISA driver?

If not, I will have to wirte a new driver. I´ve so far read the Comedi manual 
and "howto wirte a driver" notes, took a look at skel.c. But still I don´t 
quite know where to start.

Maybe some of you could give me some hints, how they wrote their drivers and 
where they startet. That´d be very nice :) And two more important questions:

- Which important things do I need to know from my board (except the 
standards like I/O address etc)? (Because manufactures normally don´t give away all 
their secrets in manuals :))
- Can I use the existing WIN3.11 driver to build a RTLinux driver from that?

Thanks very much!

Mike
