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.

Changing the Auto Insert Notify and DMA parameters for Windows 95, Windows 98, and Windows Me

To change these parameter settings from the Windows 95, Windows 98, or Windows Me desktop:

1.Click Start --> Settings --> Control Panel.

2.Double-click System.

4.Double-click CD-ROM.Select the device driver for the CD-RW/DVD-ROM Combination Drive.

5.Click Properties.

6.Click Settings tab.

7.Select or clear the Auto insert notification check box, the DMA check box, or both.

8.Click OK.
