It's SP2. Can't believe I forgot about the slipstream! I was going to make one that had the drivers install on it, just never got around to it. I know a good pack of drivers, http://driverpacks.net/. It installed some of the hardware on another computer I worked on. Combine the drivers with driver forge and you have an installer for your drivers.
For the slipstream I'm using nLite, but don't you need to add the drivers in a ".cab" file? I don't know how to make that. I did use a tool to make it, but it didn't work for some reason. I don't remember what the command was to execute. Will nLite accept the 7z files that come from the driverpacks site?
