** Note: If you intend to run Windows with 256 Colors at a resolution of 640x480 pixels or use an Apple Multiple Scan Display, Apple 16-Inch RGB or VGA display with 16 colors at a resolution of 800 x 600 you must install a display driver for the program you are using. See "Installing Video Drivers" page 39 of the User's Guide for more information.

From page 39 of the User's Guide: "Installing video drivers", select "Windows 3.1" as the application during the installation process.

If you are working with two monitors, make sure that both monitors are connected before starting the Macintosh and DOS Compatibility Card. The monitor dedicated to the Macintosh environment should be connected to the video port on the back of your Macintosh. The monitor dedicated to MS-DOS should be connected to your DOS Compatibility Card.

Troubleshooting

Symptom
Interference and no video on 13 or 14-in. display.

Solution
When you have a monitor dedicated to the DOS Compatibility Card, it must be connected to the DOS Compatibility Card prior to turning on your Macintosh. If the monitor is not connected first, you will only see the interference. In the PC Setup control panel, the monitor selection displays 16-in. The 14-in. is not available. To correct this problem, shut down your Macintosh. You must shut down your computer, restarting it will not correct the problem. Once the computer is turned off, turn it back on. You can now open the PC Setup control panel and set the Display to 14-in. and start the DOS Compatibility Card.
