Hi all,

I am helping a friend with his iMac G4 and have run into some trouble. It had the stock hard disk which was failing, so I removed it and replaced it with a 250 GB drive. Now that the machine is all re-assembled I can't get it to attempt to boot. I press the power button and get a chime. The Caps Lock key blinks, the screen goes to grey and that's it. I can hear the hard disk spinning up and performing a head-check/alignment.

I have reset the PRAM. The HDD was set to CS/Cable Select just like the stock Apple drive.

Does anyone have any suggestions?

Thanks!
