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.
