Appendix A. Customizing the device driver configuration
settings
Microsoft Windows Me and Windows 2000 Professional 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
computer’s microprocessor to perform more important tasks. For example, activating DMA might make
movies and games run more smoothly because the microprocessor is allocating more processing time to
video.
Enabling DMA for Windows XP
To change the DMA parameter setting from the Windows XP desktop, complete these steps:
1. Click Start , and then click Control Panel .
2. Click Switch to classic view on the left side of the Control Panel Window.
3. Double-click System .
4. Click the Hardware tab, and then click the Device Manager button.
5. Click the IDE ATA/ATAPI controller to expand the tree.
6. Double-click on the controller where your CD/DVD Burner is located (Primary IDE or Secondary
IDE ).
7. Click the Advanced Settings tab.
8. Select the appropriate Transfer Mode pull-down that corresponds to the CD/DVD Burner location
(Device 0 for Master, Device 1 for Slave).
9. Select DMA if it is available.
10. Click OK .
Enabling digital audio extraction
Your system must be properly configured to play back digital audio from this drive. There are two
settings that must be configured. One setting is in the device properties, and a second setting is in
Windows Media Player.
To set the device properties, complete these steps:
1. Right-click on My Computer , and select Properties .
2. Select Device Manager from the Hardware tab. In Windows Me, the Hardware tab shows the Device
Manager directly without clicking the button, as shown in the figure below.
