This is an older broadcom driver that I edited to include these wifi b/g cards which were previously unsupported in Vista, Vista 64, windows 7, windows 7 64, server 2008, and server 2008 r2. Just unpack, then open device manager. Right click the device and choose Update driver. Then tell windows to you want to choose the location of your driver and it point it to the directory you unpacked the driver in. If you get a message about unsigned driver select install anyway. That's it!! Hope everyone enjoys!
