Setup and Installation:
You must install the miroCrystal display driver available from miro Computer Products before configuring the card. Please refer to the online help of the Configure application for an explanation of this process.

The miroCrystal NEXTSTEP driver automatically sets all of the necessary parameters as specified in the Configure application.  It is not necessary to run the MS-DOS version of the configuration software when working with either of these cards under NEXTSTEP. 

When using the Configure application to configure the miroCrystal display driver, you can modify the Display Mode settings by clicking the Select button.  The Width and Height parameters are the width and height of the display in pixels. The Refresh parameter is the refresh rate of the monitor in Hertz. The Color Space parameter is of the form BW:x where x is the number of bits/pixel, and RGB:xyz/w where x, y, and z are the number of bits/component and w is the number of bits/pixel.
 
Known Problems:
The NeXT supplied S3 display driver does not work with these cards. Please use the NEXTSTEP driver available from miro Computer Products.
