I am working on an iMac right now. When the computer boots i receive:
panic(cpu 0 caller 0x002E598C): Unable to find driver for this platform: "Power-Mac4,2"
Darwin Kernel Version 8.10.2: Wed June 20 21:54:20 PDT 2007; root:xnu-792.22.6~1/RELEASE_PPC
pannic: we are hanging here.....
Then in the background there is the screen with the power button symbole and it says "you need to restart your computer. Hold down the power button for several seconds or press the reset button"
Steps I have Taken
1. First Tried to Boot to a Tiger CD i received from a friend
2. Unable to boot to cd (I press down Control and nothing happens)
3. Tried to replace hard drive. When the CD isn't in the drive it sits on the screen with a little folder showing there is no mac OS installed. Once i place the CD in the Tray it instantly goes to the Kernel panic screen.
Is there possibly something wrong with the computer itself? What is the correct way to boot to a CD? It almost seems like there is something wrong with the computer since i replaced the HD with a blank drive. Any help would be appreciated.
