I downloaded the ASD 2.5.8 and it works on my Power Mac G5 Dual 2.0 GHz.

The tests were all OK, 0 error.

But MorphOS/Mac OS X still can't boot.

I have tried to disconnect the DVD: same result.
I have tried to remove the lithium battery: same result.
I have tried to remove the keyboard/mouse: same result.

In Open Firmware, the command "reset-all" do nothing. While a "ok" is displayed for the the command "reset-nvram", the "ok" never happen (waiting 8 minutes) with "reset-all".

I have also tried the command "Command + Alt + P + R" to erase the PRAM. It show a black screen and never reboot. And after a reboot, same result.
