I am working on a 500 MHz iBook G3 with a CD drive, and 3** of RAM. I swapped hard drives with one of my backups, running Tiger with classic, as I wanted OS 9 to run on it. It went smoothly, everything worked, up until I tried to boot into OS 9 by selecting it in startup disk in Tiger. Now, when I turn it on, there is no boot noise, and I just get the blinking "?" logo. Holding down option at startup reveals the Tiger partition, but it will not boot into it, or OS 9. When I clear the PRAM, the boot noise occurs, but it continues not to play it on a regular boot. What's wrong with this comp?
