I've proved with 2 different isdn cards in mandrake 9.2. Both worked properly in 9.1 and 9.0, but in this one, the mandrake control center appears empty. In the init, the services for rdsi and ippp0 are active. The wizard/assistant, detects it and suposely configure it, but when you are going to connect. The fields are empty. It says that ther is no internet connection created. Run the wizard. I've done exactly the same in 9.1 and 9 and it worked. I think is a problem in mandrake control center. The card is not the probleme cause it detected it properly, and in previous versions it worked. (both cards isdn).
