   ===================== Cornerstone  Imaging =====================   
      
   PS/2's with XGA on a daughter card (not on motherboard) have   
   2 known problems with Fixed Frequency displays like the ImageAccel   
   Color 21/76, Color 19, and all ImageAccel Grayscale displays.   
      
   Following is a description of the fixes we've developed for these   
   problems.  These fixes are available now in LIMITED quantites   
   for customers who request it.  These parts will be included in   
   ImageAccel controller boxes in October 1993.   
      
   The problem descriptions;   
   -------------------------   
   Problem #1.   
   On any IBM PS/2 with an XGA or XGA-2 display adapter daughtercard   
   (IE: PS/2 Valuepoint Model 77), installing Fixed Frequency displays   
   is difficult without a separate XGA-compatible display attached for   
   the system configuration.   
      
   NOTE:  If you have a multisync ImageAccel display, you can use it   
   for the XGA compatible display to setup your ImageAccel card, and   
   then switch the video cable from the XGA card to the ImageAccel   
   card when the MicroChannel configuration setup is complete.   
      
   Problem #2.   
   Once ImageAccel is configured and installed, and Windows 3.1 is   
   running, changing to a DOS window or DOS Full-Screen shows   
   garbage on the screen (this is documented in the ImageAccel   
   READ.ME file for Release 1.01 and 1.02).   
      
   NOTE: This problem does not occur with the OS/2 display driver   
   for ImageAccel.   
      
   The FIXES:   
      
   Problem #1 Solution   
   -------------------   
   Step 1: Install the ImageAccel Display adapter into the IBM   
   	PS/2 mocrochannel video slot.   
      
   	NOTE: If you add or remove any other adapter cards to   
   	your system, you have to keep the connector installed on   
   	the XGA card, and boot using the boot disk to re-run the   
   	configuration program again.   
      
   Step 2: Put the diskette labeled "IBM PS/2-XGA BOOT DISK for   
   	ImageAccel" into the A: drive. (Contact Cornerstone   
   	Technical Support for information on obtaining this   
   	diskette).   
      
   Step 3: Place the Special connecter (we provide) onto the XGA   
   	display adapter port.   
      
   Step 4: Boot the PC with the ImageAccel boot disk and special   
   	connector installed. (Note: This is not a DOS format   
   	diskette - its not readable by DOS).   
      
   	Follow all the prompts for Automatic Configuration.   
   	Remove the ImageAccel Boot diskette and re-boot.   
      
   	When prompted for the ImageAccel configuration file, put   
   	the Windows 3.1 Display Driver disk 1 into drive A:.   
      
   	Follow the remaining instructions and the PC will reboot.   
      
   	DOS should now be running on the ImageAccel display.   
      
   Problem #2 Solution   
   -------------------   
   NOTE: The file PS_XGA.BAT is located on all Release 1.03   
   diskettes in uncompressed form.  You must manually copy this   
   file from the Release 1.03 diskettes to your \Windows\System   
   directory for this fix to work.   
      
   Step 1: Install the Windows 3.1 XGA driver.   
      
   	While in the Windows directory, type SETUP from DOS.   
      
   	Insert the diskette labelled "IBM PS/2 XGA Device Drivers-   
   	DOS, Windows and AutoCAD Support" (V 2.02). This disk is   
   	supplied with your IBM computer.   
      
   	NOTE:  Cornerstone tested the V2.02 XGA driver for this fix,   
   	but previous versions of the XGA driver should work as well.   
      
   	Select the Display entry under the System Information   
   	window, and scroll down to the bottom of the list.   
      
   	Select the entry: "Other (requires disk provided by a   
   	hardware manufacturer)"   
      
   	When prompted, enter: " A:\WINV31" and press enter.   
      
   	A list of XGA drivers will appear.  Select the one shown   
   	as "IBM XGA v2.02 640 x 480 256 color". (you may use any   
   	VGA driver listed with 256 Colors and 640 x 480 parameters).   
      
   	NOTE: If you are using an XGA driver other than the V2.02   
   	driver listed, you'll have to edit the batch file and rename   
   	the line in PS_XGA.BAT: XGAVD202.386 to your XGA driver   
   	to reflect the driver version you're using.   
      
   	Exit to DOS when this step is complete.   
      
   Step 2: Install the ImageAccel Display Driver.   
      
   	You have to rename IASETUP.INF file to OEMSETUP.INF on   
   	distributed ImageAccel Display Driver diskette.   
   	Follow the usual steps in the Manual for installing   
   	ImageAccel.  Don't run Windows yet.   
      
   Step 3: Copy the file PS_XGA.BAT from disk 1 of the Windows 3.1   
   	display drivers for ImageAccel into the \WINDOWS\SYSTEM   
   	directory.   
      
   	In the \WINDOWS\SYSTEM directory, run the DOS batch file   
   	called: "PS_XGA.BAT".   
      
   	Run Windows.
