I have just bought a second hand Dual 867 G4 with Mirrored Drive Doors. Its works perfectly except for the fact that I CAN'T GET IT TO BOOT IN OS 9!!!! I have now even tried wiping the whole drive (an 80gig in 2 partitions) making sure I checked the "install OS 9 drivers" box when I did this. It wont boot from an OS 9 CD or anything. I'm guessing I may need to get the original MDD OS 9 CD. Anyone know where I can get it from. Apple sy they can't help me. PLEEEAAASE HELP!!!
