Appendix C. Customizing the device-driver configuration
settings
Windows XP 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.
