Max, thanks for the link, but I think that these settings are only for this adapter-model, or am I wrong?

That's a nice barn! :–)

Appleontheapex: I think that re-seating all the connectors may have solved your problem. I've disassembled the 4400 and put it all together again. I'll try to boot it today (yesterday it bacame too late). Thanks! :–)

ArmorAlley, thank you very much for the proposal! :–) Are you sure that it supports this card, and with a "blind" install (I mean, without doing anything to the system? ; of course I can't because of the lacking graphics)

I'll write you a message later, now I have to do some homework! Thanks :–)

Nicolas
