I'm reading the document SQLServer2008FailoverCluster and I have a question from the below paragraph:
Important: If you are applying Service Pack 1 for SQL Server 2008 or later, consider using the new slipstream functionality, not only to reduce the installation time but also to have the benefit of setup fixes. If you are not going to install a service pack, you should apply cumulative updates for SQL Server Setup before you install SQL Server 2008
Please see the highlated portion. Here how can we apply cumulative updates for SQL Server setup before we install SQL Server 2008?
Please clarify me
