Hm, so let me remind you, what is handled with this configuration: With
these configuration items you will specify, which IDE controller(s) are
present and used in the hardware you are using. Surely you can have very
similar PCs which differ only in the way the IDE channels are
equipped/used. But if you look at two PCs which differ in the harddisk
configuration, you may also find that they have different network
interface cards etc, in which case you will have to use (slightly)
different BSPs again.

Once again, if anybody has an autodetect solution for the IDE driver,
please feel free to implement it in the RTEMS driver. I personally have
no idea how it can be implemented, I have currently no time to
investigate on this matter and I am glad that the problems Angelo has
detected are solved.
