It gets more complex than that Ed, he is using Mesa cards where the GPIO port pin number isn't generally the number you use in the hal file for a parport number. I needed a spindle run/brake signal on the db25's pin 17, but had to consult the dmesg output to determine the actual address of that pin for a 5i25 interface card. He is using a 5i20 + 2 daughter cards I know nothing about. I am still configuring things as I'm just now bringing it (the 5i25) to life.
