Thanks for Your answer.
It eventually did solve My problem.
Not directly but You told Me to go to the Apple site.
So, I did and searched for the firmware update page.
Apple says its not really possible to update My firmware if the firmware release is the same but they tell You how to update a normal firware update.
I should boot into OS 9 and then restart holding both the Command and start button.
This of course didn't work since I could not boot it into any OS.
But, when I held both the start and Command button it started up right into open firmware, not the first time but the second time it did.
So, PROBLEM SOLVED.
It probably reset the Open Firmware.
Thank for your answer.
