Well, I did look a lot MOL code but didn't use it for now. I won't reuse
MOL OF code, because I don't want to have hardcoded stuffs, but
something that acts really like the open-firmware and will be able to
boot any OS, just like Bochs BIOS does for PC's.
But emulated hardware from MOL will be helpfull someday. For now, I want
to concentrate on booting Linux for Prep hardware. Because it's mainly a
PC with a PPC CPU, it's a real good target to debug CPU emulation
problems without taking care of emulated hardware. Then, I want a
standard and nowedays PPC platform, not only Macs, near OpenPPC
standard. So I did an open-pic emulation, ... MOL code will be helpfull
to emulate some Mac platforms, but as it says, it seems to me that's
it's too much Mac & MacOS dedicated to help until I got full stable
basics.
