I use Nlite all the time and maybe I can help a little. I remove all the drivers and then add all of my drivers--chipset, display, modem, network, and monitor. I cannot integrate the sound driver because you can't do it with soundblaster. You have to add it after the install. Since you have onboard sound maybe you removed something that prevented it from working. Keep trying. I can do it very fast now since I've done it so many times. My XP Pro installs are about 300MB.
