So, I boot, get the ...img, to the screen where I type in 80, 81, 82, and the only one that seems anything like what I want is "Press Enter to start up Darwin/x86 with no options, or you can: but entering anything just takes me back to the prompt. I don't see any choice for OSX DVD. Perhaps I made a mistake with the USB OSX image? Can someone tell me exactly what parameters I need for the USB OSX stick? What partition format do I want, etc. I think that's the issue. I can see both USB sticks in the BIOS, so that doesnt seem to be the issue. Thanks!
