# Windows 95: Card and Socket Services

To use the Madge 16/4 CardBus Adapter, you need to be running Microsoft Windows 95 v4.00.950B (or later; the B indicates that the software is from Microsoft's OEM Service Release 2). You can check the version number by running the System applet from the Control Panel. If you are using an earlier version of Windows 95, contact your PC supplier.
