When i install my Nokia Card Phone 2.0 on my W98 machine, I am asked to insert my phonecard. Once i do that, W98 tells me that i have found new hardware, then my computer freez / hangs. I have installed the latest drivers for my card.
RE: Nokia Card Phone 2.0 Install W98
If the installation fails you should start it again and check if it could be completed at second try. If you did this and it still did not work, there could be a problem with the PCMCIA drivers and you should check if you can update them on your PC.
Another thing that might work is to install the Nokia Card Phone 2.0 to you PC before powering the PC and starting the software installation. This might allow you to complete the installation without error on the installation phase.
