I was using my iBook in the living room, and when I got up, my dog jumped onto the keyboard and knocked it off the couch while it was open. Now, whenever I turn it on, it loads the screen with the apple logo and the swirling loading icon, then goes right to the kernel panic screen that tells me to restart my computer in four languages. I've tried resetting the PMU and zapping the PRAM. Is there any easy way for me to fix it, or should I take it to the shop I got it from? (which will service it for free, but is a good distance from my house) EDIT: I can boot into Single-User Mode. It informs me that the root device is mounted read-only. I ran: sudo chmod -R u+rwx /, which took about an hour, but did not seem to change anything. Does anyone know the command that would make it so my drive is no longer Read Only?
