So I tried OF at startup and got these lines: bad Bus Info CRC-16 Apple PowerMac8, 2 5.2.5f1 BootROM built on 04/06/05 at 12:46:02 etc. -Al- On Aug 7, 2007, at 1:24 PM, Michael Cashwell wrote: On Aug 7, 2007, at 4:07 PM, Al Ciplickas wrote: This is just my understanding.

Now, I assume the first line is a hint that I have a "bad Bus" somewhere (cpu data bus?). Would the Genius Bar (with an appointment) be able to do any hardware diagnostics? Mike, I'll try the D feature on the CD _if_ I can ever get it to work, but this system is 2 years old. Would the developer MacOS Tiger DVD have the same feature? I do not think so. Each system's diagnostic tool is tightly coupled to that hardware. I've never had any success using anything other than the install/restore disks originally supplied. You might be able to take the machine to a Genius Bar (with an appointment) and they might have the right disks. Can I do anything in the Open Firmware screen to do testing? Not of the sort that the diagnostic tools do. There quite a bit of OF/EFI code being pulled from the disks in those cases that's not present in the boot FLASH. (The disks supply more than just a UI to run the tests.) This email sent to site_archiver@lists.apple.com
