I'm not sure @jimjamyahauk ever installed his. It has been almost 15 years since the start of hte project and he's moved a few times and I think started a family in that period. I'm not sure, but I think his 9700 is stored away and not easy to get to.
Have you tried booting this without extensions (shift on boot)? I've had some weird prototypes that really don't like extensions and freak out when they are enable. Just a thought.
