I expected as much, this thread was really just wishful thinking. As for corp and vlk being the same, it would seem so. But since I had to different discs with slightly different total sizes I figured their must be a little difference. I wanted to be thorough. Let me ask some add-on questions to this one then. If I want to do this as two discs, one for home and one for pro, what is my plan of attack. I want to use nlite to shrink them all down, can I use the same nlite settings files for all the versions I listed? I also want to apply the driver packs to all of them (BTS using dp base or integrating with nlite), which way is best? I also plan on making them all unattended, does the same winnt.sif apply to all those versions, or do I need a different one for pro and for home? The final question is of course what to use for multiboot, will powerpack suffice? Do I need to do something more custom?
