Contrarywise, to memory range.

By io range I meant "I/O base", in contrast to "CTL base".

There is no need to apply shifting for CTL. That's why ioport-*
appeared in the first place.

So, a matter of wrong terminology then. The thing that you meant by "I/O" is actually called "command block".

Yes. And IO is the second name.

I'd say the first place in drivers/ide belongs to the historic name "taskfile". The "command block" which is as ATA standard calls it, is hardly used.

It's used widespread in the drivers/ide/.

   Don't remember seeing it.

Now you understand why I'm so reluctant to hanging up different
labels on the single thing? ;-)
