Appendix C. Customizing the device-driver
configuration settings
Windows Me has 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.
Enabling DMA for Windows Me
To change the DMA parameter settings from the Windows Me desktop, do the
following:
1. Click Start --> Settings --> Control Panel.
2. Click on view all control panel options.

4. Click the Device Manager tab.
5. Double-click CD-ROM.
6. Click on the drive that you want to modify.
7. Click the Settings tab.
8. Click to select the DMA check box.
9. Click OK.
