I've tried several times woth several type de OSX Install Discs to install Snow Leopard 10.6.3 on a MacBook Pro Core i5, apparently it doesn't work it must be 10.6.4 or higher.

So I wonder how to integrate/merge an OSX Combo update into the install disc/image so that it installs OSX 10.6.5 directly. (Like we can do with Windows Service Packs)

Thx in advance.
