"anybody know a way i can be shure windows will be able to find them?"

Let me be blunt. Windows XP has no such feature. And "driver finder" programs are a disaster. What this means is when we elect to reinstall this OS we get to learn how to install Windows and find drivers. The 2Wire drivers are installed MUCH LATER in the install process so be sure to read your Dell Docs at (I can't supply a link because the model of the Inspiron is something I can't find in this discussion along with what CDs you have to work with). But Dell does document how to reinstall the OS.
