Hi Stevo,

No problem, we're here to help each other

Like Estrayk has shown you.
Just type those commands in the open firmware and it should boot.
To quicken the boottime I've set my "timeout" to 500 instead of the standard 3000. And it isn't important to write down "/pci/ide/disk@0,0:0"
You can suffice with "/disk@0,0:0"

Bye,

Spidey
