When I saw the title, I thought it was going this way.
Or, more specifically, a driver to turn an IDE port into GPIO pins that PC programs can control. Closing the gap on making a feature-complete Windows 95 arduino core.
I think you can do this directly, the linked project just tells the kernel "this is a parallel port here", and it just uses normal I/O instructions. The IDE port is already exactly that, though I think the data-direction register controls the whole port at once, rather than one bit at a time.
