Software Deployment

Hello,
i tried to make a silent installation of Sysmark 2007. (I also did it with Sysmark 2004--> running without problems).

1. For sysmark2007 i succsessfuly create .iss file, i do it like this -->> c:\setupfolder\setup.exe -r -f1c:\setupfolder\setup.iss
setup run itself, and i after few second quite, and see that setup.iss was created

2. First trouble - sysmark2007 using 2 CD, and during the silent installation, setup ask me to insert 2nd CD...
And now i don't even know what to do?
Maybe i need run full setup with ->setup

Thanks for help or ideas!
