Hi Andre, and thanks for this note (and of course, your work on
ide!).

1) I assume you are referring to the HP colorado 14G, and not the
Conner (Seagate) TR-4 8G mentioned in my original note.
2) If so, what could be wrong with the Conner?
3) Where can I find what is supported and what not? The Conner is a
standard TR-4, and I thought that was supported.
4) Can one signal the driver to try qic157 emulation?
5) Separately, Since the Colorado 14G seems so popular, is there any
chance of getting what it is that works currently into the new ide
stuff? After all, it *does* work at present with stock 2.2.x.

Thanks again for all your hard work!
