For a CD to autorun on a PC, it requires the setup of a file called autorun.ini. Here's an example of what the file looks like:
[autorun]
open=foo\bar\index.htm
The first line is telling the system that this is autorun instructions. The second line is specifying the position of the executatable file.
We are not able to make Mac autostart/autorun. OSX does not support this functionality. When a disc is inserted, the disc will be mounted and you can see the disc ID on the desktop.
