Apr 7, 2014 10:50 AM in response to boliddeby rccharles,I do not know why the fans are running like crazy nor do I know why you could not boot with your orginal cd.
What did hardware test indicate? How were the fans when you run the hardware test?
Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime.
Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:
reset-nvram
set-defaults
reset-all
"The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

Apr 8, 2014 1:38 PM in response to boliddeby rccharles,This is a mystery to me.
When you run diagnostics, what does that say? Did you run the memory testing?
You sure you have the correct install disc for your machine?
Did open firmware start up and did commands like
printenv
work?
You could pull out memory sticks and see if it was a memory problem?

What do you mean by this?
You could try a linux ppc distribution like Debian or Fedora. At least you could see that the cd booted.
Could try an external firewire drive. Could try target disk mode.

Apr 11, 2014 4:19 AM in response to rccharlesby bolidde,Hello Robert,
I can not do the test because I do not know ppc linux distribution and I do not have a firewire external drive. Target modes, verbose, single user do not work or I go the wrong way: (
It's weird that it starts on test drive and not on the OSX disk hardware
And I think it is unfortunate that this G5 will finish at the bottom of the cellar unfortunately
for me.
In any case, thank you for your help.

Apr 12, 2014 12:21 PM in response to boliddeby BDAqua,Hi Vincent, Robert asked for ideas here.
Only thing I can think of is to disconnect the Hard Drive & see if Single User then boots up, or if it can then boot from the Install Disc.
