- An IDE controller is a near-zero chip solution in an ISA machine, but it
- is not a bus master. It is only a tiny additional pain in the butt in
- the A600/A1200, but this is because all the same perversions needed to
- be implemented to support the PCMCIA card.

- I don't follow this logic at all.
