Appendix C. Customizing the device driver configuration settings

Microsoft Windows 2000 Professional has 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.
