Setting DMA and Display Settings in Windows

Direct Memory Access (DMA) is frequently used for data transfer directly between memory and a peripheral device such as a disk drive.
If you encounter difficulty with your DVD-ROM setup, the DMA might not be turned on.
Check the DMA and confirm that it's turned on.

1. In Control Panel, click the System icon and click the Hardware tab.
2. Select "IDE ATA/ATAPI controllers".
3. Right-click the Primary IDE Channel icon and select Properties.
4. Click the Advanced Settings tab and select the DMA check box (if it’s not selected already).
5. Click OK.

If you get an error about unavailable overlay surface, reduce the display resolution or number of colors.

"Unable to create video window. Please try altering your display settings."

To modify your display settings:

1. Right-click your desktop.
2. Click Properties.
3. Select the Settings tab and make the appropriate changes.
