Mcs9865 win7 driver

A little more information would be helpful. After a liitle investigation I see the MCS9865 is a chipset for a PCI Parallel Port Card. This kind of information would be very useful when submitting a post. Since the chipset was used by more than one manufacturer I'm not sure which of these would be useful for you but you can take a look and see.
