starting problem with an intellistation motherboard

My IBM Intellistaion Z Pro 6865 doesnt start up. The problem being that it is stuck in "power on quick test" mode. While trying to un install a graphics card, ( not the main dislay), the system had been powered down using a "force overide" (holding the power button). So the system trys to startup in quicktest but cant. It stays quicktest untill I "force overide" to turn it off. I think it is tryin use two different hardware configurations at the same time.

So now I believe my only choice is to reset the motherboard in its entirety. I read breifly that the bios can be rest by removeing the internal battery. But that kills the system time which I dont think I want to do.


What should I do to fix this?


FYI: This is not my main computer, so I'm not too worried what happens or has to be done to it.
