Hello Michael,

I dont have one MacOS Media Cd-rom, the only thing that I have is a
macos8.iso, but I dont know how can I do the boot Media with it. Is
there another way without Media Cd-rom of MacOS or without a cable? My
graphic card is a ATY, mach64.

I appreciate some help,

Thanks a lot,

Marcos
