Driverpacks has a project to try to amalgamate the latest version of every known software driver all onto one CD to create an unattended Windows XP setup disk that would work on literally any PC. And it looks like he's making extremely good headway on this project!

So far there are 8 driver packs that make up the entire project, supporting: Chipset, CPU, Graphics, LAN, MassStorage, Sound, and WLAN. The final file, Driverpacks BASE contains all the required documentation and batch files to slipstream the drivers onto a Windows XP setup CD, and even includes an UpdateChecker to ensure everything is as up-to-date as it can be.
