Appendix C. Customizing the device-driver
configuration settings
Microsoft 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 the computer performance by having the computer DMA
controller handle data transfers from the CD to memory, freeing the
microprocessor to perform other tasks. For example, activating DMA might
make movies and games run more smoothly because the microprocessor is
allocating more processing time to video.

Windows 95, Windows 98, and Windows Me
