Lenovo 43N3201 manual Enabling DMA for Windows XP, Enabling digital audio extraction

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.

2.Click Control Panel.

3.Click Switch to classic view.

4.Double-click System.

5.Click the Hardware tab.

6.Click the Device Manager button.

7.Click the IDE ATA/ATAPI controller to expand the tree.

8.Double-click on the controller where your CD/DVD Burner is located (Primary IDE or Secondary IDE).

9.Click the Advanced Settings tab.

10.Select the appropriate Transfer Mode pull-down that corresponds to the CD/DVD Burner location (Device 0 for Master, Device 1 for Slave).

11.Select DMA if it is available.

12.Click OK.

Enabling digital audio extraction

Your system must be properly configured to play back digital audio from this drive. There are two setting 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.
