Appendix C. Customizing the device-driver
configuration settings
Windows XP, Windows 98, and Window Me have two device-driver
configuration parameters: Auto Insert Notify and DMA.
The Auto Insert Notify parameter enables the computer to start audio CD
software as soon as a CD is inserted into the CD-RW drive.
The DMA parameter improves computer performance by having the computer
DMA controller handle data transfers from the CD to memory, freeing the
computer 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.
