Lets say you have all the drivers and XP updates you want on your cd - you're done and the iso is there. Now, you buy a new computer 5 months later -- so you want to add the new drivers and recent XP updates into your old iso. I was thinking - sure, just fire up nlite and add the stuff I need. Problem is, I think the drivers get installed twice - and the amount of drivers I have in there (to handle 6 models of machines) mutiplied by two, means I end up with more than 700MB. Is there a way around this? Do I always have to start with a clean source directory (the original copy of XP) before any of this done?
