Hi!
My PM G5 model 11.2 does not startup. I can hear the chime, they grey screen shows up and then there is a map with the questionmark blinking on the screen. By pressing the "open tray" button on the keybord nothing responds? Any clue.
Does it boot into any of these modes?
Holding Option/alt key at bootup.
Holding SHIFT key at bootup.
Target mode...

Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

We might get clues with verbose mode...
Hi BDAqua!
Tried out your suggestion with no luck. I had hopet that I could find the HD on the PM G5 through Firewire target disc mode, but the PM G5 went off. I connected the G5 to a MBP (intel) but no luck there. I replaced the G5s broken PSU with a PSU from another working similar modell G5 with a broken logic board. Had to take it apart completely and reassemble the machine. I pressed the SMU on the logic board before I fired up the machine. Have checked all the cables, but I cannot even perform a diagnosis and thermal calibration during ASD 2.6.3.
Have replaced the RAM with other RAM with no success.
Any further suggestion!
During startup, when I pressed the option/alt key the machine did response but the image that appear is not showing any Harddrives, only a right arrow and a circle with arrow. When pressing the right arrow agrey screen appears with the text on top;
Invalid memory access at XSRRO: 00000000. ff84604c XSRR1: 10000000.0200b030
Then they welcoms me to the Open Firmware and I get a message to continue type "mac-boot" and press retur. When doing that the machine continues to the grey screeen I had before and a filemap with the blinking questionmark.
Any clue about the message in open firmware? I did switced the Rm with other RAM and tested it. I even repaced the RAM within the slots now in 2-2.
Hmmm, sounds like maybe a logic board problem.
If you're sure the RAM is good, try the Hair Dryer trick...

No power light at all...

It can show on any G5, and even many other computers & electronic devices of the period.

Open Firmware and I get a message to continue type "mac-boot" and press retur.
Reset the NVRAM.
The machine should then restart and, hopefully, boot normally.
Look at this link http://support.apple.com/kb/HT2248
Does the installed RAM meet the requirements?
Are the RAM modules matched sets?
You said the RAM is installed in slots 2-2. Why not slots 1-1?
How many RAM modules are installed? If 4, just boot with 2 modules in slots 1-1.
Cheers, Tom 😉
To Texas Mac Man.
Yes the RAM meets the requirements, it was pulled from another same modell G5.
RAM was also placed in matced pairs, I tried out slot 1-1 first but the same issue.
Now I have 2x2 GB in RAM slot 2-2.
Thanks japamac.
Tried your suggestion, the machine responded and when typing reset-all and pressed return the machine restared but unfortunately the same issue again. The blinking filemap with the questionmark.
Other suggestion?
The one thing that is strange is that I cannot get the drive for the VD to open. pressing open on the keyboard, and the machine does not response. also tried holding down the button on the mouse during startup, but the door for the cd-drive does not open. I had hoped that I could start the machine from the install CD?
You'll have to pull down the flap covering the drive tray, then using a straightened paper clip, push the tray open via a small hole located in the front of the optical drive (typically lower, right hand side).
I did as you wrote and inserted the OSX 10.5 cd and started the machine up, but I could not hear that the cd-drive even started to spin. Tried both holding the C and then D keys down during startup, but there were no reaction ini the cd-drive.
Try rebooting & holding Option/alt key at bootup.
