I have an iMac G5 and an iBook SE (Mac OS 9). I've been trying to install OS X on the iBook through Target Boot because my iBook's cd drive is broken. It installs fine but when I try to run the iBook, the question mark folder with the finder comes up and doesn't go away. I've cleared the HD, tried again and it happened again. Does the iBook not have enough RAM, what is causing this?
