Are you sure it is going to the floppy and not a cdrom drive? If it is going to the floppy either something new and crazy has come out or someone at dell should be fired, lol. That is a cdaudio cable used when playing audio cds without using cpu time. It is a direct connection from the cdrom drive to the sound card so no system resources are used to play audio. That was useful when your computer didn't have much processing power but nowdays that is completely useless. Not only are computers much faster but cd audio is being phased out and replaced with mp3, wma, ogg, etc and mp3 players.
