Anyone able to share any information regarding installation of the PA3425U-1BTM Bluetooth Module into a Toshiba Tecra M4. I have the module on it's way, but I don't really want to pull the laptop apart any more than I have to, so it'd be nice to have an idea of what I'm doing, prior to doing it.

Once it's installed, you'll probably have to do a Fn-F8 to turn it on so Windows can load all the drivers, but if you're using a Toshiba image, the driver part should be automatic...
