Appendix A. Customizing the device driver configuration
settings
Microsoft Windows Me and Windows 2000 Professional have two device-driver configuration parameters:
Auto Insert Notify and DMA.
The Auto Insert Notify parameter enables the computer to start playing or accessing the disc
automatically after being inserted in the drive. The DMA parameter improves the computer performance
by having the computer DMA controller handle data transfers from the CD to memory, freeing the
computer’s microprocessor to perform more important tasks. For example, activating DMA might make
movies and games run more smoothly because the microprocessor is allocating more processing time to
video.
