Yamaha CRW2200S manual About DMA Settings Setting of Transfer Mode

E-IDE (ATAPI) Connection Set Up

15When using Windows 95/98/98 Second Edition/Me, follow Step 14 to open the “Device Manager” window, then double-click on the “YAMAHA CRW2200E” icon to open the “YAMAHA CRW2200E Properties” window, and click on the “Settings” tab to select it. A screen similar to the one below appears. Make sure that the “Sync data transfer” check box is not checked. (There is no need to set the “Sync data transfer” check box if it does not appear.) By checking the “DMA” check box, you can enable high-speed data transfer between the CRW2200 drive and the computer. However, depending on your computer system, this may cause operations to become unstable. If this occurs, uncheck “DMA.”

* This is a screen shown in the Windows Me environment.
