Appendix C. Customizing the device-driverconfiguration settings

Changing the Windows 95, Windows 98, and Windows Me

device drivers

Windows95, 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-RWdrive.
The DMAparameter improves computer performance by having the computer
DMAcontroller handle moving data from the CD to memory, freeing the
computer microprocessor to perform more important tasks. For example,
activating DMAmight make movies and games run more smoothly because
the microprocessor will be allocating more processingtime to video.
