Hi Everyone. I wonder if you chaps can help at all.

I don't know what happened exactly but about 3 days ago i booted my iBook and was presented with the "You need to restart your computer. Hold down the Power button for seconds or press the Restart button.

However more alarmingly I was also presented with the following:

================================================== ====================

panic(cpu 0): 0x400 - Inst access
Latest stack backtrace for cpu 0:

panic: We are hanging here...

================================================== ===================

This also happens when I try to boot either Mac OS X Jaguar or Panther. Problem is I shouldnt have Panther installed so before I send the laptop back to apple i need to format the HDD entirely. Here is the spec of my laptop:

G3 800Mhz
128Mb 100Mhz SDRAM (And 256Mb SO-DIMM from Crucial installed)
30Gb HDD
ATI Radeon 7500 32Mb GPU
12" LCD Screen
Airport Card
Combo Drive

Ive removed the airport card and the SO-DIMM memory but that hasnt made a difference. Ive reset the P-CACHE and NV-CACHE (using Apple-Ctrl-P-R) according to apples website. The apple hardware test detected an error while performing the internal memory test. Im fresh out of ideas, can you help chaps?

Thanks for your time
Daniel

Boot on OS X CD1, and launch disk utility from the Installer menu. Then repair disk & permissions.

If it's not enough, you should try to do a clean install...

Hi.

Thanks for the reply but the iBook wont even boot off the Mac OS X CD at all. For some bizarre reason it brings up a Unix command prompt but I dont know any commands that can format the HDD.
