   PURPOSE   
   To instruct Cornerstone customers on the installation of the ImageAccel   
   video controllers with IBM XGA video controllers in PS/2 computers.   
      
   ACTION   
   When installing the ImageAccel Micro Channel video controller, you must   
   leave the installed XGA controller in the computer. This is necessary   
   for the ImageAccel video controller to frame grab XGA signals for DOS use.   
      
   The ImageAccel video controller must be installed in the secondary video   
   slot. When the computer is booted, the ImageAccel controller will not be   
   seen by the computer due to the XGA BIOS ROM, until the PS/2 Reference   
   Disk is used to install the ImageAccel configuration file.   
      
   If you are installing a Cornerstone Color Monitor, you will need to   
   attach the monitor to the XGA controller to run the PS/2 Reference Disk.   
   After setting the configuration for the ImageAccel controller, you can   
   then attach the monitor to the ImageAccel controller. Remember, you must   
   leave the XGA controller in the computer.   
      
   Installing a Cornerstone monochrome monitor requires the use of a VGA \   
   XGA display to run the reference disk. After setting the configuration   
   for the ImageAccel controller, you can then remove the VGA \ XGA display   
   and use the Cornerstone monochrome monitor as the primary display. You   
   must leave the XGA controller in the computer.   
      
   UPDATE 8/11/1993   
   Cornerstone now has a VGA Terminator to make the XGA controller act like   
   a VGA   
   controller in Windows. Cornerstone also has a configuration Boot   
   diskette to make the Cornerstone ImageAccel controller the primary video   
   controller. To obtain the VGA Terminator connector and Boot diskette,   
   please contact Cornerstone Customer Support.   
      
   If you have any questions regarding the installation of ImageAccel video   
   controllers in PS/2 computers with XGA video controllers, please contact   
   the Cornerstone Customer Support at at the phone numbers below
