Creating a merged (slipstreamed) drop containing SQL Server 2008 RTM + Service Pack 1

Today, I am going to show you how to create new source media that will slipstream the original source media and SQL Server 2008 Service Pack 1. Once you have created this drop, you can install SQL Server 2008 SP1 in a single step! These instructions are included with the Service Pack 1 release but there are some issues with the documentation that will be addressed in the next revision of the on-line documentation. There is not a lot of user interface that indicates you are slipstreaming, but there are a few clues, see at the bottom for screen shots.
