ddtest will test out your graphics adapter and print out
what it's device driver is telling us. In some of the OS/2 2.1
drivers, OpenGL was getting bad information from device drivers,
which would stop us dead in the water.

Please run ddtest as follows:

    ddtest > ddout


Afterwards  the file ddout should contain text which will help 
us determine if your graphics adapter has a good driver on it.

Thanks,
The OpenGL on OS/2 Team
