RE: pci 6025E and 8255 support

Some things I forgot, You will have to do a rmmod of all the current modules
and reload them, the 8255 line with it compiled correctly on an lsmod should
look something like this:

8255                    3776   0 [ni_pcimio]

and yes it will be device 3, with 24 IO points.

Hello -- 

I have successfully been using the ni_pcimio driver with my 6025  
card, and now wish to begin using the digital I/O features as well. 

the following output from the "lsmod" program is:  
-bash-2.05b# lsmod 
Module                  Size  Used by    Not tainted 
ni_pcimio              28544   0 
mite                    4684   0  [ni_pcimio] 
8255                    3520   0 
comedi                 23956   0  [ni_pcimio 8255] 

the following output from the "info" program is:

how can I gain access to the 8255 subdevice? Does it is subdevice 3 ?  

Thanks,
