Problem running Thermal Calibration G5 Quad

http://forums.macrumors.com/archive/index.php/t-1719325.html


So after my fun adventures with my new 2.7GHz G5, I have done lots like rebuilding the LCS. The last thing I did was swap the two CPUs due to heat, and I went to go re-calibrate them with ASD 2.5.7 and the thing says it will take 10 to 20 minutes per processor to calibrate. I've sat here for 40 minutes ago and it's stuck on the same task since 40 minutes that is "Calibration starting on CPU0." With no updates this far into it. Anyone have an idea or two?

I also can't move the mouse cursor, and pressing a key on the keyboard like caps lock, does not light up.

Edit:

Fixed with using ASD 2.5.8

Took about an hour and a half, but all is good now. When opening a program the fans will jump up then back down.



Hello I found the above problem on Macrumours and it is exactly what i am experiencing however when i tried to use ASD 2.5.8 i get a small terminal window come up bottom left saying open firmware with some error found,i tried reset-nvpram and reset-all but system reboots and still wont go into diagnostic test screen,i also removed all the ram bar two sticks and have managed to run ASD 2.6.3 and ran the memory test and they passed fine.

The system boots fine into osx with no problems but i want to calibrate the fans as i re-applied paste and want to ensure everythng is fine.



Can anyone help?

Connect your G5 and plug it in, cross your fingers, and hold down Opt-Cmd-O-F while turning it on from the power switch. If you did this right, one of the front red LEDs will briefly light and then turn off, the G5 will bong and you will enter the Open Firmware prompt. (If you don't get a bong, the CPU is not in place correctly or, horrors, is damaged. Loosen it and remove it. See if it will boot with the old CPU.) Release the keys, type eject cd to open the optical drive, put your ASD disk in, and close the optical drive. On my ASD 2.6.3 disk, I had to type boot cd:,\diags (yes, you need the colon, the comma and the backslash) to start the diagnostic program, the only time your G5 will ever "appear" to boot Mac OS 9. 🙂 The fans will come on full blast; this is normal and the fans will remain loud during the entire diagnostic process.


I think the thermal test has to be done within open firmware but i've tried doing the above but the cd:diags prompt does not load the image from my dvd,i can do devalias and see a tree list of my devices but could do with some help to figure out how to load the test from the dvd.

If it's the Dual Core/PCIe models I think 2.6.3 is needed.


Maybe we can infer what 2.5.7 & 2.6.3 cover by what's before & after what is covered by 2.5.8...


2.5.8 version is compatible with the following Mac models ONLY:


PowerBook G4 (17-inch 1.5GHz), PowerBook G4 (17-inch 1.67GHz),

PowerBook G4 (15-inch 1.5/1.33GHz), PowerBook G4 (15-inch 1.67/1.5GHz), PowerBook G4 (12-inch 1.33GHz), PowerBook G4 (12-inch 1.5GHz),

iBook G4 (Early 2004), iBook G4 (14-inch Early 2004), eMac (USB2.0),

Power Mac G5, Power Mac G5 (June 2004 Series), Power Mac G5 (Late 2004),
