I already looked at that image --- the AHT-BootInfo (the only Mac OS ROM-ish file on that CD) script does boot, but its a smoke-and-mirrors trick. It executes a file called 'exec' and that file is coded in Objective-C which came from Next which means its not what we're looking for. It only looks like OS9 because thats the way they wanted it to look. It could be that somthing in the ROM-to-RAM dump that we need to merge from BootX that just wont jive on a new mac. There's something else making MacOSROM not boot on a OSX machine, but I am starting to believe something in OpenFirmware is refusing to boot that file. I have found that booting directly from OF gives more detailed information than the "System Picker". I'll keep on messing with it though.

And I'll grab that image -- I had downloaded the same image for the Powerbook G4 Aluminum.

I think if it is possible to boot OS9 from a OSX-only machine, it'll be tricky.
