You don't need to integrate any service pack, your copy of windows comes with sp1 already. You can call addon a pack, because basically it's the same thing. Here's the integration process with screenshots http://24.14.156.63/nfm/page/updatepack/integration.html Those links may not be valid in the future, I'm still playing around with server. I'am too late,http://24.14.156.63/nfm/page/updatepack/integration.html is invalide now. Anyway, I have problem. In nlite, it has integrate driver.How do i use it?I have 64-bit motherboard chipset,but i can't find the .inf document.In Taiwain, we have Super XP and Auto xp. I don't know if your country have those CD.Nlite can not create Super xp or auto xp,because it can not integrate softwares.In super xp, softwares can automatically install bt itself.By the way , could you provide some link about forum?.I not native speaker.It will spend alot of time for me to find the forum.I think that foum will alot of resource for me to learn. The forum in Taiwain , it provide alot of file to download ,but a little about teaching.
