how to install them.

			  *  *  *

Section One - ImageAccel Control Panel for PMShell

The ImageAccel Control provides you with flexibility in the
ImageAccel high-resolution display through the selection of feature
options that control things like Desktop and Viewport size, Zoom and
Pan hotkeys, Cursor and Icon size, Power Save mode, and others. Use
the options described below to customize your PMShell desktop with
the ImageAccel Control Panel.

In Release 1.00 and 1.01 of the ImageAccel display drivers, a mini-
control panel was available for WIN-OS2.  That mini control panel is
deleted for Release 1.02 (and later), and all the Control Panel functions
available for both WIN-OS2 and PMShell are integrated into the ImageAccel
Control Panel for PMShell.

NOTE:  Some of the features provided by this new control panel are NOT
available while a WIN-OS2 Seamless or a Command Window session has focus.

After you install this release for the first time, the ImageAccel Control
Panel will pop-up. On some notebook pages are the buttons Default and
Undo.

These buttons affect only the settings on each page. Selecting the Default
button returns the values on that page back to the factory defaults.
Selecting the Undo button returns your previous values for that page.

Make your changes and shutdown and restart for the new settings to take
affect.  Note that you'll have to restart WIN-OS2 if it was running
when you made control panel changes before they'll take affect.  On
subsequent restarts, the ImageAccel Control Panel will be found in the
Minimized Icon Viewer (or minimized to desktop, if you set that option).

Beginners may want to select the default settings for each page before
closing the control panel.  Note that not all changes require a
shutdown and restart.  In those cases, you will not be prompted to do
so, and simply closing the control panel will make the changes take
effect.

NOTE: Selecting a logical DPI of 150 or higher may cause unusual affects
in some applications due to limitations in those applications.

The ImageAccel Control Panel works just like any other OS/2 notebook,
except that it saves your changes each time you turn a page.  Note
however, that your changes may not go into affect until the shutdown
and restart is completed.


Information Notebook Page
---------------------------------------------------------------------------
This page gets information from your installed ImageAccel hardware and
software to aid in troubleshooting.  The following information is
displayed;

   Hardware:            Model, Board Type, Resolution and Monitor Code.
   Display Driver:      Version, Build Rev, Build Date

NOTE: The display driver shown on this page for Release 1.03 actually
shows 1.02 as the installed driver.

On this notebook page, clicking the button marked README displays this
IAREADME.TXT file in an editor window.

Display Settings Notebook Page
---------------------------------------------------------------------------
This is a special notebook page that has two category tabs located at the
bottom left corner of the notebook (near the 'binder').  When you first
click this tab, you'll be in the General category.  This category provides
settings to be used for all display environments - PMShell, WIN-OS2 and
Seamless.  The settings on this page are not individually configurable
for these three display environments.

 General
 -------
  Desktop Size:
   The Desktop Size option selects the virtual desktop size.
   For Color systems your choices are:

   ImageAccel 1600      ImageAccel 1600/76   	ImageAccel 1280/76
   1984 x 1024		1600 x 1280		1984 x 1024
   1600 x 1200					1600 x 1280
   1280 x 1024					1280 x 1024
   1024 x  768					1024 x  768

   Changing the Desktop Size option does not change the appearance
   of the display.

  Viewport Size:
   The Viewport Size option selects the resolution that is actually
   displayed on the monitor.  For example, choosing 1280 x 1024 displays
   1280 pixels horizontally and 1024 scan lines vertically.  For color
   systems your choices are:

   ImageAccel 1600      ImageAccel 1600/76   	ImageAccel 1280/76
   1600 x 1200					1600 x 1280
   1280 x 1024                               	1280 x 1024
   1024 x  768                                	1024 x  768

   NOTE:
   1600 x 1200 resolution is only supported for 76 KHz displays and
   above.
   1280 x 1024 resolution is only supported for 64 KHz displays and above.

   With a Viewport Size smaller than the Desktop Size, only a portion of
   the full Windows desktop will display.  Dragging the mouse to the edge
   of the screen moves the viewport in that direction, and exposes the
   remainder of the desktop.

  Logical DPI:
   The Logical DPI option selects the logical dots per inch for use by
   OS/2 and OS/2 or Windows applications.  ImageAccel gives you four
   options:
	96
	120     (default)
	150
	192

   OS/2 and applications use the Logical DPI to determine the size of many
   elements such as rulers and scalable fonts.  The larger the logical
   DPI, the larger the size of these elements.

   Every application uses the Logical DPI slightly differently, so, when
   you change the Logical DPI, some application elements may change size,
   and some may not.

   NOTE:  A number of common commercially-available applications do not
   operate correctly at Logical DPI's above 120 due to defects in these
   applications.  If problems occur, use the ImageAccel Control Panel to
   change the Logical DPI to 120 or below.

  Cursor/Icon Size:
   The Cursor/Icon Size option selects the size of system OS/2 and WIN-OS2
   icons and cursors together (they are not individually selectable).

   The system cursor/icon size is not dependent on the Logical DPI.  The
   choices are:
	Standard     (default)
	Large

 WIN-OS2
 -------
These settings apply to WIN-OS2 full-screen and WIN-OS2 Seamless
environments  only.  Where indicated Full-Screen only, that feature is
not available for Seamless WIN-OS2 or PMShell.

Full-Screen and Seamless Windows System Font:
Select from three choices;
	Standard     (default)
	Large
	Extra-Large

Full-Screen Windows only Cursor Color:
Allows you to select the color of the Full-Screen WIN-OS2 cursor.
This option allows you to select the color which is most comfortable
or noticeable for you.  The choices are;

	Black			White
	Dark Red		Light Red
	Dark Green		Light Green
	Dark Yellow		Light Yellow     (default)
	Dark Blue		Light Blue
	Dark Magenta		Light Magenta
	Dark Cyan		Light Cyan
	Dark Gray		Light Gray

    NOTE:  The WIN-OS2 seamless cursor color is white.  The PMShell
    cursor color is black. These cursor colors are not changeable to any
    other color. This is an OS/2 limitation.

    Full-Screen Windows only ImageAccel Enhanced System Palette:
    This provides the enhanced ImageAccel palette including access to the
    16 hardware gray shades needed for document imaging.  This is the
    default setting.

    Full-Screen Windows only Compatible System Palette:
    Use this option for better palette compatibility when using photo
    editing applications like Adobe Illustrator or Photoshop.
    This setting is not recommended for Document Imaging applications.

Power Save Notebook Page
---------------------------------------------------------------------------
  Enable the power save feature:
   Selecting this feature on supported displays will put the display system
   into power-save mode after the selected time has elapsed with no
   keyboard or mouse activity.  This feature is grayed out if you're
   installed on a system that does not support it (Except for grayscale
   displays - look for Energy Star logo on back of display).  The default
   setting is disabled.

Zoom and Pan Notebook Page
---------------------------------------------------------------------------
 Select Hot Keys:
  The ability to Zoom in on an image is important for any application that
  requires manipulation or analysis of highly detailed images.  For
  example, signature verification on scanned document images, or detailed
  pixel editing for graphics applications benefit from zooming
  capabilities.

  ImageAccel's zoom features allow you to zoom in to any of the available
  zoom levels and back again with a single hot key.  These hardware
  assisted zoom features work in combination with any software zooms
  provided by your application.

  The Select Hot Keys notebook page configures user-definable keys for
  ImageAccel's Zooming and Panning features.  The default for each Hot Key
  is Disabled. Select the Enable option to activate each Hot Key.  You
  may use the pre-defined keys, or choose to define your own key sequences.

 Zoom In:
  Each time you press the Zoom In Hot Key, the screen enlarges the image by
  one step.  At each level the screen blanks then positions itself so that
  the cursor is approximately in the center of the zoomed display area.
  The table below shows the zooming resolutions available through the Zoom
  In Hot Key for Color displays;

   ImageAccel 1600      ImageAccel 1600/76   ImageAccel 1280/76
   1600 x 1200		800 x  600		1600 x 1280
   1280 x 1024		640 x  512		1280 x 1024
   1024 x  768		640 x  512		1024 x  768
   800 x   600		512 x  384
   640 x   512		400 x  300
   512 x   384
   400 x   300

 Zoom Out:
  Each time you press the Zoom Out Hot Key, the screen shrinks the image by
  one step.  At each level the screen blanks then positions itself so that
  the cursor is approximately in the center of the display screen.  The
  table above shows the zooming resolutions available through the Zoom In
  and Zoom Out Hot Keys.

 NOTE:  You cannot zoom out to a resolution greater than the Desktop Size
 as declared on the ImageAccel Control Panel.

 Zoom Restore:
  Pressing the Zoom Restore Hot Key while in a zoomed mode restores the
  display to the selected viewport size as defined in the ImageAccel
  Control Panel.  Pressing the Zoom Restore Hot Key again returns you to
  the previously viewed zoom level.

 Pan Lock:
  Pressing the Pan Lock Hot Key locks the Viewport at the current position
  on the Windows Desktop.  When locked, moving the mouse to the edge of
  the screen does not move the Viewport.  Pressing the Pan Lock Hot
  Key again unlocks the Viewport and allows panning around the Windows
  Desktop.

NOTE:  See Section 3 for more information on the ImageAccel Control Panel.

        IBM 9521/9527  (supported by the C/11 and C/12 only)

        NOTE:  ImageAccel xc1608C/10 does not support these displays!

     Generic Settings:
     -----------------
     The generic settings choices are renamed for this release.  These
     choices now show the resolution by REFRESH rate of the display,
     instead of the horizontal scanning frequency.  This is to make it
     easier for you to match the appropriate display timing for your
     non-Cornerstone display.

     NOTE:
     We also removed the Cornerstone DualPage 120 Color choice.  For that
     display, please use the generic choice that reads;
           'ImageAccel 1600x1200 at 64Hz'.


	New for Release 1.02 	  	        Was (Horizontal Scan Rate)
     	-------------------------------        	--------------------------

applications running under WIN-OS/2 (Full screen mode only).

*   NOTE:   DO NOT USE THE NATIVE WINDOWS 3.1 DISPLAY DRIVERS
	    WITH OS/2 2.1.  DSPINSTL.EXE automatically installs
	    and configures the PMShell, WIN-OS/2 and SEAMLESS
	    drivers for both Color and Grayscale display
	    systems - no other drivers are needed.

*   NOTE:   IBM COMPUTERS with an XGA daughter card (like the
	    IBM Model 77 with the  Microchannel Bus) REQUIRE A
	    SPECIAL VGA TERMINATOR ATTACHED TO THE XGA
	    VIDEO PORT ON BOOT-TIME FOR OS/2 2.1
	    FULL SCREEN MODE. SEE   SECTION 10 - IBM Model
	    77 Microchannel Configuration for more.
					
Since ImageAccel supports VGA, you can use it with any software
written to the VGA interface standard.

			  *  *  *

Section Three - New Features with this Software Release

1. Support for the IBM 9521 and IBM 9527 displays in included.  Note that
Energy Star mode for these displays is disabled for this release.  These
displays exhibit one known anomaly with the WIN-OS/2 session Screen Saver
Flying Windows which may cause stray horizontal lines to appear on the
screen. This problem has no impact on your system or any other applications,
just hit a key or move mouse and choose another screen saver to prevent this
problem from occurring.

2. This release includes better installation support for OS/2 3.0 WARP
(full version with WIN-OS/2 included), and 'Split Installs' for OS/2 2.1x
or 3.0.  See WARP installation instructions in Section Twelve below.

Split Installs: We built the install scripts using the WARP %WINPATH%
variable to accomodate installations where WIN-OS/2 or DOS is not included,
or when installing WIN-OS/2 onto a different logical drive from the OS/2
core. NOTE: The DSPINSTL.EXE used in this release is from the OS/2 2.11 DDK
toolkit.

3. Several pre-release driver files are included that fix some bugs, but
are not integrated into the installation process.  See Section Four for
more information.

			  *  *  *

Section Four - Problems Fixed with this Software Release

The default installed drivers for this release are the same drivers installed
with Release 1.02.  Please see the 1.02 IAREADME.TXT file for a listing of
the problems fixed in Release 1.02.

For your convenience, we have included a set of pre-release drivers, but 
they are not automatically installed in 1.03.
We have performed limited testing only on these pre-release drivers.

Section Seven  - Known Problems with ImageAccel Hardware

For PC168Ci and PC128Ci Color controllers with revision -006A
or lower:

1. IBM 6091 fixed frequency Displays are not supported as a boot display.

2. Jumper 8, Default Boot Screen, is not functional.

For MC168Ci and MC128Ci Color controllers with revision -003A or lower:

3. IBM 6091 fixed frequency Displays are not supported as a boot display.

4. ROM Shadowing.  If your CMOS or Flash EEPROM settings have
ROM Shadowing enabled in the same space that ImageAccel is
using (default DE000 - DFFFF), then unpredictable results may
occur.  We recommend disabling ROM Shadowing in ImageAccel's
memory space if this is causing problems in your system.

5. BUG525 - Checkit's Colors Are Not Correct in some modes.
This is an ImageAccel limitation.

			  *  *  *
	
Section Eight - Hardware Installation

Installation Notes:
Before installing the ImageAccel controller, disable the VGA
on your computer's motherboard if it does not disable
automatically when it detects a VGA card.  Remove your add-in
VGA card if you have one, or disable ImageAccel's on-board VGA
by removing jumper V to use another VGA source.

*   NOTE:  Refer to Section 10 - IBM Model 77 Microchannel
	   Configuration for instructions for configuring
	   ImageAccel with an  IBM PS-2 Model 77 or any IBM
	   PS-2 machine with XGA on a daughter card.

*   NOTE:  For IBM PS-1 Valuepoint computers (Model 425SX/S)
	   you must disable the motherboard (S)VGA.  To do
	   this, remove jumper 17 on the IBM's motherboard.
	   (IBM informed us that some Valuepoint motherboards
	   silk-screen show this as jumper 13, even though the
	   labels and other documentation show it to be J17).

It is essential that ImageAccel not conflict with either the
memory or I/O addresses of any other controller in your system.
Your ImageAccel controller has been pre-configured for memory
addresses DE00-DFFF and I/O addresses 3B0/3B1.  If you need to
change these defaults, change the jumpers as described in the
User's Guide.

IMPORTANT:  ADDRESS B600-B7FF:
Do not use address range B600-B7FF unless all other selections
create a conflict, as this range inhibits normal operation.

B600 address shouldn't be used because it lies between
A000-C000 (VGA address space).  In any system that doesn't
have the VGA board embedded, ImageAccel will work but will
have problem when VGA mode 13 is used.  This will conflict even
with our own VGA.

In a system with the VGA onboard such as DELL, AST...etc.,
when you "disable" the onboard VGA, it is NOT 100% DISABLED
and will still cause problems.

The symptoms are;
       o  PMShell or WIN-OS/2won't start or return to DOS, OS/2 hangs.
       o  Both VGA or ImageAccel comes up with a blank screen.

Hardware Installation Procedure
-------------------------------
1. Turn OFF and disconnect the computer from the power source.

2. Remove the cover from your computer.

3. Verify the jumper settings.  The factory default settings have
been chosen to work with most system configurations.  If you need
to change these defaults, please refer to the Jumper Configuration
section at the end of Chapter 3, Hardware Installation, of the
ImageAccel Installation Guide.

For PC/AT systems the default configuration is:
   I/O address:		3B0 - 3B1
   Memory space:	DE000 - DFFFF
   Display type:	DualPage 120 (DualPage 120i controller)
      DualPage 150	(DualPage 150i controller)
      Autosync		(Color controllers only)
   Boot to:		High Resolution display
   On-board VGA:	Enabled

For Microchannel systems the default configuration is:
   Display type:	DualPage 120 (DualPage 120i controller)
      DualPage 150	(DualPage 150i controller)
      Autosync		(Color controllers only)

4. Install the Display Controller in a 16-bit expansion
slot, or the Video Adapter Slot for Microchannel systems.

5. Using the video cable supplied with your system, connect
the 15-pin connector to the High Resolution connector on the
installed Display Controller.  For PC/AT bus controllers
this is the UPPER connector.

*   NOTE:  For proper operation of PC/AT bus controllers, the
	   high resolution display MUST be connected to the
	   UPPER connector on the ImageAccel controller.

6. Connect the other end of the video cable to the display.

For Color controllers only:  Connect the five BNC connectors at
the other end of the video cable to the back of the display
as follows:

 Cable Color             Display Connector

 red				R
 blue                           B
 green				G
 refer to marking on cable	H
 refer to marking on cable	V

*   NOTE:  To ensure high resolution display quality,
ImageAccel requires that you use the 15-pin to 5 BNC video cable
supplied with the color controller.

7. Connect the power to the display and the computer and
power both units ON.

For Microchannel systems:
The system error 165 will appear on the display. When prompted
for the Reference disk, Insert OS/2 2.1 Display Driver for ImageAccel
disk one (it contains the file @80A6.ADF) to re-configure your
Microchannel system for ImageAccel.

Section Ten - IBM Model Microchannel Configuration

ImageAccel Microchannel display adapters include a VGA Terminator
and an IBM PS/2-XGA BOOT DISK for ImageAccel that are required
to get ImageAccel running without using a separate XGA or
multisync display.

The IBM Boot disk for ImageAccel is used ONCE, to get the
Model 77 to recognize and boot ImageAccel.  The VGA Terminator
is required at BOOT TIME, to change the XGA adapter into VGA
mode, so ImageAccel can run OS/2 properly.

CAUTION:  You must leave the VGA Terminator attached to the XGA
display port at BOOT TIME.  If you don't, then PMShell full
screen prompts will paint your screen black (type ALT + HOME
to remedy  this temporarily, changing the Full screen mode to
a Prompt window).


IBM Model 77 Setup
-------------------
NOTE: Leave the XGA card in the proprietary IBM primary video slot.

Step 1: Install the ImageAccel Display adapter into the IBM
	PS/2 Microchannel video slot (2).

*   NOTE:  If you add or remove any other adapter cards to your
	   system, you have to keep the VGA Terminator
	   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 VGA Terminator (3012682-002) onto the XGA
	display adapter port. (Contact Cornerstone Technical
	Support for information on obtaining the VGA Terminator).

Step 4: Boot the PC with the IBM PS-2 Boot disk for ImageAccel
	and VGA TERMINATOR installed. (Note: The Boot disk is
	not a DOS diskette - its not readable by DOS).

	Follow all the prompts for Automatic Configuration.
	Remove the IBM PS-2 Boot diskette and re-boot.

	The system error 165 will appear on the display. When
	prompted for the Reference disk, Insert OS/2 2.1 Display
	Driver for ImageAccel disk A: (it contains the file
	@80A6.ADF) to re-configure your Microchannel system for
	ImageAccel.

	Follow the Automatic Configuration instructions and
	the PC will reboot.

*   NOTE:  Once the Microchannel system has read the ImageAccel
	   setup file (@80A6.ADF), you may remove and add other
	   ImageAccel boards without running Automatic
	   Configuration again.  The @80A6.ADF file works
	   for all ImageAccel display adapter boards.

Now your system is ready for you to follow steps in Section 11.

			  *  *  *

Section Eleven -  Installing OS/2 2.1 Display Driver for ImageAccel

This procedure assumes that you have OS/2 2.1 installed on your
system, running in VGA mode on the ImageAccel display system.

If you install OS/2 on ImageAccel using the XGA driver supplied
with OS/2 2.1, no cursor will appear on the ImageAccel display.

Follow IBM's instructions for installing OS/2 2.1 to VGA before
attempting the steps below.

1.  We STRONGLY recommend that you edit CONFIG.SYS so that OS/2
    boots directly to the command line prompt:

	  PROTSHELL=C:\OS2\CMD.EXE

    This allows for recovery back to VGA (SVGA or XGA) when
    necessary.

    NOTE: If you keep a backup of your system, AND you've
    successfully installed the ImageAccel high resolution drivers,
    it's safe to restore booting to PMShell.

2.  We also STRONGLY recommend you set your restart option.  Add
    the following line in your CONFIG.SYS before the line that
    reads "SET AUTOSTART = ...."

	  SET RESTARTOBJECTS=STARTUPFOLDERSONLY;

    Type PMShell to start Presentation Manager.

3.  After you verified PMShell runs in VGA/XGA, we STRONGLY
    recommend you completely back-up your VGA (SVGA,XGA)
    configuration BEFORE installing ImageAccel high resolution
    display drivers.  This will allow you to return to VGA/XGA
    without losing the current desktop.  The following steps
    will preserve the current VGA settings.

    Install OS/2 and all applications, including and Windows
    applications.

    Make a backup copy of the following files;

	OS2\OS2.INI
	OS2\OS2SYS.INI
	OS2\MDOS\WINOS2\WIN.INI
	OS2\MDOS\WINOS2\SYSTEM.INI

    At the command prompt, type

	copy OS2\*.INI *.VGA
	copy OS2\MDOS\WINOS2\WIN.INI WIN.VGA
	copy OS2\MDOS\WINOS2\SYSTEM.INI SYSTEM.VGA

Your system is now prepared to install OS/2 2.1 display drivers
for ImageAccel.

ImageAccel's OS/2 2.1 High Resolution Driver Installation
---------------------------------------------------------

*   NOTE:   If you have any difficulty with this installation of
	    the OS/2 2.1 Display Driver, run the DSPINSTL.EXE
	    program again and choose the VGA Display Driver.  If
	    you have the same or similar problems installing
	    OS/2 2.1 for VGA, contact IBM for installation
	    support.

 1.  Run PMShell (VGA mode) and then insert the OS/2 2.1 Display
     Driver for ImageAccel disk 1 in drive A:.

 2.  Log on the A: drive: (or double-click on the A: drive
     Icon in PMShell).

 3.  From Drive A:, type DSPINSTL.EXE and press [ENTER]

 4.  Select Primary Display, then Click the OK button.

 5.  Select your display type from the list, then Click the
     OK button.

 6.  Select the display resolution from the list, then Click the
     OK button.

 7.  Insert ImageAccel driver diskette #2 when prompted.

 6.  The Display Driver Install dialog box will reappear.
     Click on Cancel.

 8.  Remove the diskette from drive A: and shut down then cold
     boot your system.

*   NOTE:   The first time you boot the PMShell desktop,
	    ImageAccel drivers builds a large data file, setting
	    up the parameters for your display.  For 486
	    machines, this process may take up to two minutes.
	    For 386 machines, this start up mode takes longer.

	    No disk activity will occur during this process.
	    Subsequent starts will be much quicker.

 9. After you have installed the ImageAccel high resolution
    display drivers, and you've run PMShell to verify that the
    install completed successfully, we strongly recommend that
    you make a back-up copy of your ImageAccel settings by
    preserving the following files;

    This will allow you to return to ImageAccel without losing
    the current desktop.  The following steps will preserve the
    current ImageAccel settings.

    Make a backup copy of the following files;

	OS2\OS2.INI
	OS2\OS2SYS.INI
	OS2\MDOS\WINOS2\WIN.INI
	OS2\MDOS\WINOS2\SYSTEM.INI

    At the command prompt, type

	copy OS2\*.INI *.IA
	copy OS2\MDOS\WINOS2\WIN.INI WIN.IA
	copy OS2\MDOS\WINOS2\SYSTEM.INI SYSTEM.IA
			
			  *  *  *
	
Section Twelve - Installing OS/2 3.0 WARP with ImageAccel

Personal WARP vs. full WARP 3.0:  For full WARP 3.0 - that is the version
that INCLUDES WIN-OS/2, no special installation instructions are needed;
simply follow the normal installation procedure. For Personal WARP 3.0 -
the version that DOES NOT include WIN-OS/2, follow the steps below.

Depending on the file dates for your version of WARP, some ImageAccel
installation files may be older that the ones on you system.  If so, you
will be asked if you want to replace them during the install process.
You may answer either Yes or No, and the installation will proceed
normally.

RECOMMEND STEPS to Install Personal WARP
----------------------------------------
This release provides Personal WARP display drivers for WARP's PMShell,
and WIN-OS/2 Seamless.  Since Personal WARP requires native Microsoft
Windows 3.1, you must use ImageAccel's native Windows 3.1 drivers for that.

The recommended procedure follows.  Note:  Like all OS/2 installations, it's
important to get EVERYTHING - mouse, SCSI, hard drives, etc. - working in VGA
before attempting to install the IA high-resolution driver.

NOTE:  Personal WARP does not include Windows.  To get Windows, you must
install native Microsoft Windows 3.1 BEFORE installing WARP. (We do not yet
have a procedure for installing WARP followed by Win 3.1).  Windows for
Workgroups seems to work just as well as Windows 3.1.

1. Install DOS

2. Install Microsoft Windows 3.1 to VGA.  Get all devices running in VGA.

3. Run ImageAccel's NATIVE Windows 3.1 Setup program from Release 1.05.
Test Native Windows 3.1 before installing WARP to be sure everything
is running normally.

4. Install OS/2 3.0 Personal WARP.  Get all devices running in VGA.
NOTE:  Warp seems to have problems supporting (recognizing) some
third party devices.  If you cannot get your device working in VGA, it
will not run in ImageAccel either (trackballs, large hard-drives, odd
network cards, etc.).  These are WARP limitations.

5. From the OS/2 Release 1.02 for ImageAccel, run our DSPINSTL program
from your floppy diskette.  When complete, shutdown and restart.  When
you reboot, you should come up to high-resolution in WARP.  However,
Windows will not yet be configured.

6. Execute the following command from a command prompt;

XCOPY \OS2\MDOS\WINOS2\SYSTEM\*.* \WINDOWS\SYSTEM

NOTE:  If it is different, you must substitute the actual name of the
directory where you installed Microsoft's Windows.

(We do not yet have a way of detecting where the user installed Windows
3.1, so this step is manual.  We are looking at ways to make this step
better for 1.02, however, we will not delay 1.02 for that.)

7. Shutdown and reboot.

You should now have FULL driver support for WARP.  The WARP install
program writes two special entries to the \WINDOWS\SYSTEM\SYSTEM.INI file
to support Full-screen and Seamless Windows from WARP.  They are;

	SYSTEM.INI
	[BOOT]
	sdisplay=IA_SEAM.DRV
	fdisplay=IA.DRV

If your entries don't match these, then Win 3.1 will not work correctly
under WARP.  If the files that these entries are pointing to are not
in the right place, then it won't work (Step 6 does that).


PERSONAL WARP 3.0 KNOWN PROBLEMS
--------------------------------
1.  Clipboard
The Clipboard functions work differently in Personal WARP than in OS/2 2.1x.

You can CUT/COPY/PASTE text or graphics from a full-screen program to another
full-screen program, or from a seamless program to another seamless program,
or from a PMShell program to another PMShell program.  The WARP clipboard is
separated for each session.  You cannot clipboard copy from say, full-screen
to seamless, or even Full screen to PMShell.

In OS/2 2.11, you can CUT/COPY/PASTE from Seamless to PMShell, or from
Fullscreen to Seamless, and vice-versa, etc.

This may be a WARP limitation - we'll investigate.

2.  ImageAccel Control Panels
With OS.2 2.1x, our OS/2 control panel for ImageAccel controls BOTH WIN-OS/2
settings, plus the PMShell settings.  Because WIN-OS/2 does not exist in
WARP, our PM control panel automatically disallows changes to the full
screen Windows side, and will only manage the PM and Seamless settings.
(NOTE: setting a large ICON for PM will give Large Icons in Seamless but
not in full-screen).

Because the native Windows 3.1 driver is actually fully installed, including
our Win 3.1 IA control panel, it will control the full-screen session only.
If you want the PM/Seamless settings to match to the full-screen Windows,
you have to make the same settings in both control panels.

It's possible to get things out-of alignment, if for example you set large
system font for PM/Seamless and small fonts for Full-Screen Windows. We
recommend you make settings match for both environments, or strange
results may occur.

3.  Scale-To-Gray
Scale-to-Gray is supported in EXACTLY the same manner as in OS/2 2.1x.
I.E.:
	PMShell		Supports S-T-G in hardware
	Seamless	Supports S-T-G in SOFTWARE only
	Full Screen	Supports S-T-G in hardware

			  *  *  *

Section Thirteen - Installation of ImageAccel Displays in a CID Environment

At the time of this Release, CID installation instructions for 1.02
had not been finalized.  Therefore, no instructions are yet available
for installing ImageAccel Release 1.02 into a CID environment.

Please use the Release 1.01 display drivers for installing ImageAccel
into a CID environment.  The instructions for that are in the Release
1.01 IAREADME.TXT file included with that release.

Call Cornerstone Tech Support at the numbers listed below for up to date
information on CID support for this release.

Section Fourteen - Tips and Troubleshooting

1. VGA Restore / ImageAccel Quick Reinstallation Procedure

NOTE: This process may not preserve ALL of your Desktop settings.
See Section 11, above, or the ImageAccel Installation Guide for
details on ensuring all your Desktop settings are preserved.

If it becomes necessary to reinstall ImageAccel, or you need to
restore VGA quickly, use the following process (NOTE:  Be sure
to type the following EXACTLY, or you may damage your OS/2
installation).

1.  Change to the \OS2\DLL directory
2.  Type 'Del CTI*.*     CAUTION: entering the wrong keys here
    can kill OS/2, forcing a reinstallation of OS/2.
3.  Change to the \OS2\IMAGACCL directory
4.  Type Del *.*           CAUTION: entering the wrong keys here
    can kill OS/2, forcing a reinstallation of OS/2.
5.  Shutdown OS/2 and reboot. Run PMShell

Your OS/2 2.1 system will come up in VGA mode.

2. WIN-OS/2 Program Installation

It is usually safest to install Windows 3.x programs in VGA mode.
(then switch back to the ImageAccel high resolution drivers once
you've verified the Windows program is running in VGA mode).

When installing Windows applications under WIN-OS2, ALWAYS respond
NO to updates for your CONFIG.SYS or AUTOEXEC.BAT entries.

3.  WordPerfect Print Preview

You have to setup WordPerfect to use the VGA driver for the Print
Preview to work in OS/2.  This will not change the PMShell driver
settings.

	1.  In OS/2 Full screen, type WP <filename>
	2.  Press Shift-F1 keys to get the setup screen
	3.  Select 3 for display
	4.  Select 5 for graphics screen type
	5.  Select IBM 640x480, 16 colors

4.  Lotus 1-2-3 - Setting up Expanded Memory for very large
spreadsheets

Setting up very large spreadsheet EXPANDED MEMORY space causes
memory error messages.  To prevent this you must EXCLUDE the
ImageAccel memory space. Refer to page 308 in the booklet
"OS/2 2.1 - Using the Operating System".

ImageAccel default memory space is DE000-DFFF.  You must exclude
this space when assigning extra expanded memory for Lotus 1-2-3.
All versions of Lotus 1-2-3 use expanded memory and look in the
C000-CFFF range to find it.

If you set ImageAccel to CE000-CFFF, this is a direct conflict
with Lotus 1-2-3.  The recommended DOS settings are;

EMS_MEMORY_LIMIT 12
MEMORY_INCLUDE_REGIONS 		C0000-CFFFF
MEMORY_EXCLUDE_REGIONS		D0000-DFFFF (ImageAccel
default)
