Sorry, Zion -- I'm afraid I haven't heard of that problem, either. I successfully installed XP on my Macbook Pro back in July or so, but I don't have all of the hardware complications you have with all of your extra drives, etc.

I haven't spent a lot of time on the Apple forums, but I would also recommend the MacRumors forums -- it's a great community, and I've seen many problems solved there.

Good luck, and keep us posted on what happens! I'm interested to see how the problem gets resolved.

Take care,
Sojourn
