We tried that too :-}  Without BIOS initialisation, the chip won't work.

The x86 emulation approach was led by a company,
but I seems they got to know the chips well enough in the meantime to
program them directly...

The emulator was based on x86emu, and the last time I saw it was in one
of the {linux,free}bios projects. I actually ran it once with a M6 BIOS
on a PPC,
but it didn't work right away and I didn't wanted to dig in there at the

While I would be interested to hear about any progess you can make with
