I was not clear but what I want is something that works for long-term
production systems. It seems that DoC is unsuitable in the long term due
to DoC limitations and M-systems lousy attitude.

I'm thinking in terms of what a company like could ship to
users. The IDE-FLASH would have to be either slave on the primary channel
or master on the secondary channel. But wouldn't a slow IDE-FLASH on
either channel make the other device run slowly? I thought this used to
be the rule -- the IDE bus ran only as fast as the slowest device?
