PCI DDA08/16

Hi...we have been trying to get a Measurement Computing DDA 08/16 board to 
talk to a simple process that writes a waveform to all analog output 
channels...in addition to this we are also trying to write a square wave 
over two digital lines to synchronize our code...the 8255's on the PCI DDA 
08/16 should be accessible...however while loading the driver we notice 
two messages pop up saying 

"8255 support not configured -- disabling subdevice"

i guess this prevents us from finishing the requirement on the current 
assignment...the board seems to respond ok on low frequency signal 
generation...is there anything we need to change on the 
install/config...our modules are loaded in order as
8255,cb_pcidda,cb_pcidas,kcomedilib,comedi after which we run the 
comedi_config command for the two boards in our rc.local as...

"comedi_config /dev/comedi0 cb_pcidda"
"comedi_config /dev/comedi1 cb_pcidas"
