I have created all of the settings in nlite just the way I want them for a number of versions of Windows (2ksrd, skadv, 2k3std, 2k3ent) I call a set of custom scripts as part of the install. These scripts execute the same way from each version of the OS, so the only thing I need to change is the scripts (in the $OEM$ directories, and some of the $OEM$ files 1. if I change files in the $OEM$ directories, I do not need to re-run the whole nlite compilations, I should only need to recreate the ISO. Correct? 2. is there a command line I can use to create the ISO directly? I know that there are ISO creation tools such as CDIMAGE out there (I have a copy from WINPE). Is there anythign special that needs to be done with creating the ISO? 3. Can I take the cirestory structure NLITE creates and burn that directly to a CD? Do I need to do anything to make it bootable? Or will it boot by virtue of the file directory structure on it. Thanks in advance for any help....
