I was recently using the program Onyx to verify and repair permissions when my iBook G4 crashed. I tried rebooting, but instead a black screen with the the following messages came up:

Jun 3 13:40:37 init: can't exec /bin/sh for single user: Exec format error
Jun 3 13:41:07 init: can't exec /bin/sh for /etc/rc: Exec format error

I have no idea what happened to my iBook! I tried restarting from the tech tools cd that came with the AppleCare, the Software Install, and the OSX cd. None of them worked. When I put in the Software Install cd, it told me to type in "mac-boot" or "shut-down." The other two cd's didn't boot up at all. I also tried Safe-Boot. Nothing is working right now. I've been trying to troubleshoot this problem all night and I've had no luck. Do I need to take it to a shop? Will the AppleCare Warranty cover software related problems? I don't think it's my hard drive. Well, I hope I can get some feedback on this problem. Thanks.

Try zapping PRAM and have the OS X CD in and boot from it using C. Otherwise hold down Option and choose what to boot from. I had this problem with my iMac. When I did so in running total maintenence, it wouldn't even boot up to Verbose mode, it would just crash. I had to reinstall X.

Yeah, I forgot to mention I tried zapping the PRAM. That didn't work either. Hopefully booting up with the option key held down will work. Tryin' it now. If not I hope someone can answer my questions in this thread!

No go. I'm running out of ideas and patience. I'm reluctant to call AppleCare because a handful of people told me they had to wait and wait, but then again they were idiots, as where I am not ;).

I tried booting from the Software Install Disc 1, Norton Utilities, Tech Tools (AppleCare), OSX 10.2 CD, OSX 10.0 CD, and Disc Warrior. When I try booting from the Software CD, it goes to open-firmware and when I type "mac-boot" and enter, it goes to the same black screen as when I am booting normally.

When you tried to zap pram, did you do it by the cmd-option-p-r way, or by the open firmware way? I'm not 100% sure they're completely equivalent. Try the commands to reset pram/nvram instead of mac-boot at the OF prompt.

The commands are:

reset-nvram
reset-defaults
reset-all

Yeah. Tried both ways. Nothin. I'm thinking there's a problem with the system folder? Although when I hold down the option key at start-up, it recognizes my hard drive, "The Drive of Terror," and when I choose it to boot up, it goes to the black screen with the error text in what I'm thinking is the SUM.

Won't boot from CD, huh.. do you have the Open Firmware password set?
No. I have never fooled around with Open Firmware. I'm assuming if I haven't set or designated a password, there isn't one?

Shooting in the DarK: What about File Vault or the "Master Password"?
Well, I set the master password on open firmware, but to my knowledge and fishing around on my damned computer, It still won't boot up correctly. I still give the command "mac-boot," and from there it says:

invalid memory access at $SRR0 056`094c %SRR1:00003030

and then from there give again the command "mac-boot" and the flashing folder with the question mark appears.

I wasn't looking for you to turn it on, quite the opposite. Sorry if that led you down the wrong path.

What version of OS X are you running? Maybe we can fix the permissions on /etc/rc. Do you have access to another Mac? Maybe we can boot the CD on it and put the iBook in target mode and reinstall the OS.

I have OSX 10.3 freshly installed on my iBook, but when I boot my iBook up the Apple logo appears, and then a pixellated box covers the Apple logo and doesn't load up anything more from there. When I target-mode my iBook, the hard drive appears normal and I can remotely control it too. But my iBook won't boot up past the Apple logo.

You did a clean install? Did you erase the disk first (after backing up your data)? You're having a lot of problem with this. If you've done a clean install and you're still having problems, chances are that this is a hardware problem and requires a trip to a Certified Apple Repair Specialist.
