removed the ubuntu disk out of the main drive, and it let me startup tiger from the USB DVD. what do ya know, it booted. Leopard is installed on the main HD.

I added a 256 stick on the bottom, and the machine booted fine from the HDD, it didnt panic so someone must have removed the RAM which is why it was panicing. However, it only sees that stick as 128mb PC100, its a 256MB PC133 high density chip.
