I can't find any options to configuring autoplay on multiple disks.
Here's what we would like to accomplish. For cd1: Install or launch. For cd2: Launch or request cd1.
This can be done but you need to manually create the autorun.inf file for the second disk. For the second autorun you can create an exe file or call a VBscript that verify the disk label (see label entry in autorun.inf) and prompt to insert the expected disk.
