Section 1 - Overview of ImageAccel
ImageAccel integrates high resolution, fast speed image
decompression, scale-to-gray image enhancement, and
extremely fast Windows acceleration on a single chip.
Ultra-fast Windows Performance
With ImageAccel's on-chip Windows acceleration you can open,
close, move, size and scroll windows with blazing speed.
ImageAccel was specially designed to maximize overall
Windows performance.
Scale-to-Gray
ImageAccel's built-in scale-to-gray engine enhances image
quality lost in the scanning and scaling process. Resulting
images are easy to read, with no performance loss.
Hardware Assist for Document Imaging
The ImageAccel Display Controller incorporates hardware assist
for decompression, scaling and rotation of bi-tonal document
images. This provides exceptional image display rates without
the cost of traditional hardware-based decompression.
VGA Support
For PC/AT bus systems, non-Windows applications use ImageAccel's
on-board VGA, which can display on either the high resolution
display or on a separate VGA display connected to the ImageAccel
controller. ImageAccel's on-board VGA provides 640 x 480
resolution, and 16 colors out of a palette of 262,144.
For Micro Channel bus systems, ImageAccel provides VGA
compatibility by attaching to the VGA controller on the system
motherboard.
* * *
Section 2 - New Features with this Software Release
1) Full Microsoft Native Display Setup Support
The driver is installed using the Windows NT Display Settings
setup found in the Windows NT Display Properties.
2) Overscan option is provided in the ImageAccel Tab of the
Display Properties for the Cornerstone DualPage 120 Grayscale
Display. Overscan is enabled as the default. NOTE: The
DualPage 150 display does not include an overscan option.
The display is from bezel to bezel for this display.
3) Cornerstone Imaging Contact Information is provided in the
ImageAccel Tab of the Display Properties in the INFO page.
4) Hide ImageAccel Icon - The ImageAccel Icon in the Windows NT
taskbar represents an application that is currently running. You
may remove the ImageAccel icon from the taskbar if you wish by
clicking the option marked "Hide Desktop Icon" in the ImageAccel
control panel. Your zoom and panning options will remain in
effect. You may later access the ImageAccel control panel
through the ImageAccel Tab in the Microsoft Display Properties.
5) U.S. EPA Energy Star Compliance - The ImageAccel Power Save
feature is software that switches the display to Power Save Mode
(lowest power consumption) after a user definable time period in
which you have not used the keyboard or mouse. The Power Save
feature is only available with Energy Star compliant Cornerstone
displays. Most of these displays are identifiable by the Energy
Star logo on the back of the display. The Power Save feature is
compliant with the VESA DPMS standard for power management.
6) ImageAccel Zoom Hotkeys - 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. The Zoom Hotkeys are disabled as the default. You may
enable them through the ImageAccel Tab of the Display Properties.
7) 32bit toolkit Scale to Gray support including applications
built on the High Level 32 bit Toolkit v. 4.0 and Low Level 32 bit
Toolkit Release 3.00 GA.

* * *
Section 4 - 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: For IBM PS-1 Valuepoint computers (Model 425SX/S, 56,)
we strongly recommend disabling the motherboard
VGA. To do this, remove jumper 17 on the IBM's
motherboard.
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. Do not use address range B600-B7FF unless all
other selections create a conflict, as this range inhibits
monochrome VGA operation (the DOS command MODE MONO).
If you use an ImageAccel Controller with a monochrome MDA or
HGA controller, you can not use I/O address 3B0 and memory
address B600-B7FF. In addition, you need to add VGA MonoText=0
to the [386Enh] section of your SYSTEM.INI file.
Hardware Installation Procedure
1. Ensure that the system is configured for VGA mode (640x480x16
or 256 Colors)
2. Turn OFF the computer.
3. Remove the cover from your computer.
4. 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

Section 6 - Installing the Windows NT 4.0 Display Driver
If the ImageAccel Windows NT 4.0 display driver is being
installed for the first time, you must first start
Windows NT in VGA (640x480) mode before proceeding. If an update
installation without a display/adapter configuration
change is being performed, it is not necessary to revert
back to VGA before installing the display driver. If the
display/adapter configuration is changing and an
update installation is being performed, we
recommend that you first uninstall the existing
ImageAccel display driver before proceeding.
The ImageAccel Control Panel automatically runs the first time
you run Windows after installing the ImageAccel software.
NOTE: Be sure to complete the hardware installation before
you begin the following Windows NT Display Driver
installation. The system will hang during boot if the
adapter's switch settings are incorrect.
NOTE: Using the Windows NT 4.0 "DETECT" feature in the
Display Properties Change Display Type page will install a
standard VGA driver from the Microsoft Windows NT 4.0 CD.
To acquire ImageAccel functionality, you must follow
the following installation instructions.
CAUTION: Be sure that all other applications are closed
before proceeding. If other applications are running while
new display drivers are installed, the system may not
function properly or may hang.
1.Right click on the desktop and pick
"Properties" to bring up the Display
Properties window. Choose the "Settings"
tab.
2.Select the "Display Type" button. A display type
dialog box will appear. Select the "Change..."
button in the "Adapter Type" section of the box.
3.A "Change Display" dialog box will open. Select the

NT should be restarted. You can restart
the system at that time or later, depending
on your needs. NOTE: Selecting an
inappropriate display type may distort the
screen or bring up the VGA display driver
instead. If this occurs, simply reinstall the
correct display if the display can be read,
otherwise, select the VGA display from the
boot menu upon powering up the system.
6.Restart Windows NT.
NOTE: After restarting Windows NT, a
Windows NT "Invalid Display Settings"
dialog box will appear with the
following information: "A new graphics
driver has been installed. The old default
display resolution has been temporarily
used by the system. Use the display
option in the Windows NT Control Panel
to select your preferred Display
Resolution." This message is a
misleading message generated by the
operating system. Select OK to ignore
the message and continue.
7.Choose your desired settings through the
Windows NT Display Properties "Settings" and
"ImageAccel" Pages. Some changes to the
Control Panel default settings require you
to restart Windows before the changes
