Writing a new driver for a DAQ Card - help needed

Hi Everyone,

First off all, I am very new to driver writing.

I want to write a driver for a Humusoft MF 614 Card for comedi.
I already wrote a simple kernel module which got the card talking using
outb() commands with the baseaddress. I have the full documention with all
registers & addresses.

I read the whole Comedi Documentation a couple of times, but still it
confuses me. Especially Chapter 5 (Writing a Comedi Driver).
I modified the skel.c driver a bit and wanted test it.

I have two big problems:
1. I fail at Chapter 5.6 "Integrating the driver in the Comedi library".
There is no file "comedi/Config.in" where I have to add the "dep_tristate"
line.
I downloaded several different versions and also from CVS, but I simply do
not find that file. Where is it?

2. To make DAQ Card talking, I have to add the base addresses and registers
to the skel.c driver. The sourcecode of skel.c uses arguments like
"dev->iobase" + "SKEL_DIO_CONFIG", but where do I set that arguments?

Your help is very appreciated, thank you very much in advance.

Peter
