OK, First I want to thank those who replied. But I guess I wasn't specific enough. I'm creating a new build of XP Pro with SP3 integrated, and I want to eliminate 1394 networking entirely. I know nLite can do it for me, but I then don't learn anything, and beside that, the rest of my builds, both CD\DVD or networked, have always been built manually, by yours truly. Sure I've made my share of mistakes, but I try and learn from them, hence my desire to do it all myself. An addition to my previous questions: As long as the INF files that configure the "1394 Net Adapter" aren't loaded during Windows setup, do I really have to elminate the other files, like .SYS or .DLL etc.? Thanks again.
