After I installed the IBM International ISDN PC Card in Windows 95, I reinstalled CardWizard for Windows 95. Now the adapter is not properly recognized any more. What can I do?

The device driver installation instructions for Windows 95 state:

Some notebook computer manufacturers install PCMCIA support software such as SystemSoft's CardWizard as part of the Windows 95 package. IBM includes this program with its ThinkPad notebook computer series. This section briefly describes how to remove CardWizard from the system. This software must be removed to ensure correct operation of the IBM International ISDN PC Card.

When you reinstall CardWizard for Windows 95 –even the latest version available– you might see a message from CardWizard like the one illustrated below:

You can get the adapter to work by stopping it in CardWizard, removing the adapter from the PCMCIA slot, and then reinserting it. However, you might have to do this every time you want to use the IBM International ISDN PC Card, regardless of whether you hot-insert the card or cold-start your system. The best solution is to completely remove SystemSoft's CardWizard software from Windows 95 and use the adapter without it.

I have followed the instructions for installing the IBM International ISDN PC Card in Windows 95. I am using Windows 95 OSR 2.x. Whenever I try to hot- plug the adapter, the system freezes. What can be done to solve this?

It appears that there is a problem with the PCMCIA support in Windows 95 OSR 2.x. This problem was not seen in the initial release of Windows 95 and Service Pack 1. If you experience this problem, then the only solution is to cold-insert or cold-remove the adapter, i. e. shut down and turn off your notebook computer, insert or remove the IBM International ISDN PC Card in any PCMCIA slot, and then restart your computer.
