I assume I could've written in German, however then the others don't 
understand what we're talking about...

Ah, OK I see.

I would be really, really grateful for that. Then maybe I can find out 
what is wrong with the card. I was wondering already what the TCA650 was 
doing on the card.

My email address given in this posting is the real one.

Well, I haven't used slot 7 so far, so I think it might not be

in a slot.

Thanks a lot in advance.
