if you do not have a svcpack.inf file, make sure you don't ahve a svcpack.in_ in your I386 folder after nLite. If so, simply EXPAND svcpack.in_ back to svcpack.inf and open in notepad and add to it, then MAKECAB svcpack.inf . Otherwise (I'm sure you have a svcpack.inf if you've used nLite for hotfixes) just simply create the file yourself. Open in notepad, add the required sections and save it. And as a side note, this is more of an ADDING to the CD, and not an Integrating. Integrating/Slipsteaming would be replacing the orignal files with the updated ones.
