How could I extract drivers from installers?

Here is my problem: I am making ready to vlite a windows install cd, and I’d like to integrate the pc manufacturer’s original drivers in the iso. However, these come as exe auto-installers, which I can’t use for my purpose. Is there a way to extract the drivers from the installers? I seem to remember there was a program that did just that, but the name escapes me.
Thank you for your help,
