In Remembrance
If you have an old system, and do not have a CD, or cannot get drivers from anywhere, it would be a good idea to backup all the installed drivers on the system, including the Windows drivers. Or, even if you have the CD, or the drivers, I will still recommend backing up the drivers, and storing them at a safe place, just in case. Its always better to be on the safe side.
