The [mci] section of the SYSTEM.INI file lists the device types installed in the system. If you have a particular device type installed more than once, the device type names in the SYSTEM.INI file have integers appended to them. This creates unique names for each MCI device type entry. For example, if the “cdaudio” device type is installed twice, the names “cdaudio” and “cdaudio1” are used to create unique names for each occurrence of the device type. Each name usually refers to a different CD audio player in the system.
