I think that the only option I'm aware of is…to contact Apple (via phone) and ask them for an original set of discs that shipped with Mac Pro 1,1's. There may be a small charge.
I know that some folks have done this previously…but…considering how old this model is (8 years approx.)…Apple may no longer do this. Since about with the "Late 2011" model Mac's…Mac's no longer shipped with these disks.
Apple loves to "move forward"…and they may have discontinued any internal systems for handling these requests. But you never know…you may get lucky!
If you decide to pursue this…please let us know what Apple was able to do…so others with a similar request may benefit.
Long shot but try this. Go to the link, scroll down to Mac Pro and click on Mac Pro 1.1 and a 4.4MB .dmg file will be downloaded. Double click, and drag System folder to left hand pane of Disk Utility, pop in a CD and hit burn and you MAY have a bootable copy of AHT. Good Luck.
I have a mac pro 1.1 what o.s was it running what is the problem you are having please more detail's would be nice and you can't boot from the downloadable version of hardware diagnostics you have to install it and run it.
There are ton's of mods you can do to that model of mac pro including speed boosting the machine so exactly what are you trying to do??
Thanks for your responses. The problem that I am having is browser and finder freezes which forces me to force quit the computer by pressing the power button. I have done several clean installs of the OS, used Disk Utility and Disk Warrior numerous times. The computer will work normally for days and then the problem starts up again and I have to force shut down over and over again. Then it stabilizes for awhile only to start the freezing process all over again. It is not a disk problem because two different disks with the OS on them have the same problem. I am running 10.6.8 because I have software that will not run on later OS. I don't think that it is a RAM problem because I have removed RAM modules (two at a time; there are six), restarting with various combinations of the modules and the problem persists. It is as if the machine has some underlying weakness in some hardware component that is on the edge of failure but still works sometime, most of the time or hardly at all. I have never had this problem with many Macs I have owned through the years. I still have a PowerMac that works just fine but is too slow for what I need to do, process scanned photographs, not to mention that browsers no longer work with Panther. This is why I wanted to run AHT, as a last resort to abandoning this machine which is a big upgrade to the PowerMac.
Here is another wrinkle to this issue. If I boot in safe mode (safe boot), the problem goes away. I guess that means it is a software issue. Suspects include Adobe Flash Player and MacKeeper which I started using recently. In Safe Mode, I can't play video in Firefox, but I really don't care about that. I just want the computer to stop freezing.
