I recently loaded linux yellowdog onto my G4 2x450. After successfully installing and using for quite some time, I decided to take out the hard drive which was in my computer and replace it with a new one. My intention was to put a fresh install of os 10.2 which i just purchased. All I'm getting confronted with after the computer is booted is an apple logo then a circle with a line going through it. Now the problem... List of symptoms and things i've tried. a.When force booting from CD you can hear it spin up , but it slows down again and eventually we get a screen that alternates betwen a folder and a question mark. b. I tried another cd drive, same thing. I disconnected the data cable from the hdd and connected it to the cd tried to boot, same thing. c. Norton Utilies cd wont boot. d. I've tried my working cd drive on my working data cable on all his ide controllers, it will not boot. e. Removed all pci devices except video card. f. Reseated all ram, then tried booting with each individual module g. Hdd also seems to spin up but doesent sound like it's being read. h. Tried zapping pram I dont know what else to try, any help greatly appreciated.
