Sounds more like a system problem. If you didn't read the Mitsi MMCS CD you would have a blue screen with an instruction to insert the disk. I'm not sure what your screen would look like if you need to put in a boot disk (after power disconnect). There is a site dedicated to fixing all these little problems but at the moment they are having some server problems I'll list the link below so you can keep an eye on developments.

Just remember that this system wasn't meant to leave Japan as it was still being developed. We have many Jap imports in NZ and are use to these little problems. Ussually the models are several years ahead of anything else (ABS, trackion control, ECU and many bells + whistles to name a few).
