The “board” must be yours and not a one that comes with a system. It should
be done in such a way that it will not be picked up by any of the Microsoft
supplied drivers, which include a lot of standard devices. You can test and
work using the PortIO code since it will “own” those ports. This is good
for testing, but I would never recommend you attempt to release a product
using one IO per IoCtl. You could make it more inefficient by adding a few
hundred wait states to the card itself, but not a good idea.
Look at www.pcisig.com for info about doing a card. It will be expensive,
but you can join and gain access to vendors that make PCI chipsets. They
can also test your designs, or so I hear. I am a software type, but have
worked with hardware folks for several years, on and off.

It may be used within a product.
