"Byte-bashing" IDE (for lack of a better term) with a suitable hardware
interface really is quite trivial and doesn't require a great deal of code
(especially PIO mode). The only tricky part is complying with the timing on
the status register - not reading it too *soon* rather than too late - so on
older hardware it's probably not so much of an issue.
So it's probably better to roll your own from scratch rather than attempt to
port the linux driver to os9/nitros09?!?
