Appendix C. Customizing the device-driver
configuration settings
Changing the Windows 95, Windows 98, and Windows Me
device drivers
Windows 95, 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-RW drive.
The DMA parameter improves computer performance by having the computer
DMA controller handle moving data 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
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.
3. Select Device Manager.
4. Double-click CD-ROM.
5. Click Properties.
6. Select Settings.
7. Click Auto Insert Notification or DMA.
8. Click OK.
Changing the Windows 2000 DMA parameter setting

1. Select Start-->Settings-->Control Panel.
2. Double-click System.
3. Click the Hardware tab.
4. Click Device Manager.
5. Click on the IDE ATA/ATAPI controller to open up the tree.
6. Double-click the device that corresponds to your CD-ROM port. It is
either "Primary IDE" or "Secondary IDE."
