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" 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 the following order in the rc.local 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" -Ashish
