All the time we travel , or for others reasons we leave our computer´s drivers at home, it is important to have always a second option, if eventualy we need to format or make some PC´s configuration.
One of these days i found a very interesting tool that maps all hardware containing on our PC.
The software called My Drivers is an utilitary described by the author as a
