Appendix C. Customizing the device-driver
configuration settings
Windows 95, Windows 98, and Windows Me 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 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 will be allocating more processing time to video.
