My primary computer is a Macbook Pro (late 2011) with Mountain Lion. Recently, I found an old Power Mac (G4?) Cube at my work that had the clicks of death. I happened to have an old 300GB IDE hard drive taken out of an old PC desktop and did the old switcheroo. I did format the old drive (can't remember how) before putting it in the mac. Now of course when it boots, it shows the little mac icon and a question mark. I'm assuming that this means it can't find an operating system, as should be the case. I have a 320GB USB Transcend Drive I used to SuperDuper! my MacBook Pro, thinking I could boot the Power Mac with it. I know now PPC's cannot boot off of USB drives but what are my other options? There is a CD in the drive, I tried putting a copy of 10.8.1 from my install on it, to realize there is no getting it out now. (I guess I haven't tried turning it on and holding the eject key) I don't have a firewire drive available to boot from either. Is there any way to boot off of a network connection? And would I have to buy another copy of 10.8.1 that's compatible with PPC? I know how to change the BIOS on Windows computers to boot in a different order buy I've never had to learn how to do it on Mac. Any help would greatly be appreciated.
