DEFAULT CATCH!, code=300 at SRR0: 5555554 SRR1: 40003030 typing 'mac-boot' gets me to a white screen with black lines all down it. It just hangs there. I tried zapping the PRAM but it didn't help. The hard drive has been making those *click click* 'I'm about to die' sounds for a while. I'm assuming its the hard disk . I have another iBook with a failed logic board I can take the HD out of but in case its not I don't want to take it apart just yet. Opinions?
