I am honestly curious (for my own satisfaction) as to what the natsemi docs say the delay code should do (can't imagine they say "use io port 80 because it is unused"). I don't have any copies anymore. But mere curiosity on my part is not worth spending a lot of time on - I know you are super busy.

I hope that the solution turns out to simplify matters, and hopefully to document the intention of the resulting code sections a bit more clearly for the future.
