In my previous article we have discussed about Basic slipstream setup, now Im going to write a article on Merged Drop slipstream setup. In this method you will be merging the service pack with the base setup prior to the installation there by altering the source or base setup files. The merged setup package can be reused multiple times and you can burn it in DVD or copy it to a network share. However the main thing is that you need to TEST this setup package before promoting it as the core setup or live setup copy.
