Solved my problem with a new hard drive and the retail os x 10.4 install dvd by using target mode and my iBook to remote install. After the install, software update ran and updated my os to 10.4.11 and suddenly all problems have gone away and machine is working. Thanks to all who helped. I never did get an answer to my question, what does "invalid memory access" mean? Now that the machine is working I guess it doesn't matter, still just curious.

When trying to boot from the installation disk I get the message that I can't install Mac OS x on this computer, this is after the language choice screen. I've been told that it is because my version (X 10.4.1) is too early for the intel macbook pro and that I need 10.4.6 or later. I have ordered the restore dvd's from ifixit that are for the A1150 pro and just waiting delivery. Is this version stuff causing my problem with my hard drive cooperating? I have also tried a new hdd (wd160 gb) but just get a file folder with a ? in the flashing at me. Tiger (10.4.1) will install and boot from the new drive when formatted in the apple scheme but not when formatted in the GUID scheme (when using an ibook g4 and fire wire remote install) it says that mac osx cannot boot from it. I'm hoping all this is because of the ppc/intel compatibility and sooner or later I can get my pro back without having to take it to an apple repair shop. Last three of serial are VJ2. So is the problem compatibility of the intel machine?
