Where to add an answer file to the Windows 8 DVD media

Hi,

I would like to use my answer file when manually building computers from the Windows 8 DVD media. Where does the answer need to be stored on the Windows 8 DVD so that Setup will use its settings during the installation process? The last time I did this was with Windows XP so I'm not sure if this ability exists with Windows 7 or 8.

Thanks,

Rob
