Hello mates!
Some good and some bad news.
I had a few days free and after trying a lot of things I know what the problem is.
Seems one of the CPU was died ( or semi died)
I exchanged them by luck and voilà...It works again!

Now Im a bit afraid why it died and I looking to the temperatures.
Morphos shows 72 grades Centigrades in one cpu and 53 in the other.
What are normal temperatures in a 2.0 ghz G5?

Another problem was that after reseting all type of things seems that I need to recalibrate temperature sensors.
Fans are loud until Morphos starts.

I have tried to use Apple CD to calibrate it but it cant...It sais I have to change cpus. (dont know if where the correct cd version).

And another problem. I cant enter OpenFirmaware. Seems it cant recognise muy keyboard at startup (it is the same I used always).

But hey! I think It is a good sign it runs MorphOS.

Hope you can bring me some ideas.
