I hope this question hasn't already been beaten to death, but I can't find it anywhere. My question is quite simple: Is there a way to integrate program installations into my automated install. For example I want to see if it is possible to automatically install things like Firefox, WinRar, OpenOffice, etc. Secondly, and along the same lines, is there a way to add drivers that are bundled into an executable file to my automated install, as most drivers are commonly distributed that way now. I hope someone can help me. Thank you.
