The board's documentation uses the old x86 > segment:offset notation of 0xDA00:0000, which I think is 0xDA0000. Have you tried 0xDA00 ? This should allow access to the first port. To make use of the second port, try loading the driver with io=0xda00,0xdc00 0xDA00:0200 is another way of saying 0xDA00+0x0200 = 0xDC00 Check the DIP switches and ensure that you have the correct address set.
