Micro Channel Configuration 6. Installing the Windows NT Display Driver 7. ImageAccel Control Panel 8. Known Problems with the Windows NT Display Driver 9. Known Problems with Windows NT and Windows Applications Windows NT 4.0 is supported with this release. This release does not support Windows NT 3.5 or Windows NT 3.51. This is the final Windows NT 4.0 ImageAccel 1 display driver release. No Windows NT 4.0 ImageAccel 1 display drivers will be developed in the future. * * * 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 3 - System Hardware and Software Compatibility Hardware Compatibility: For information about the particular computer hardware or operating system that you are using, consult the documentation provided with your computer.

Software Compatibility: Microsoft Windows NT 4.0 and all Windows applications. Since ImageAccel supports VGA, you can use it with any software written to the VGA interface standard. * * * 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 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 Micro Channel 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 Micro Channel systems, and replace the computer cover. 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 Micro Channel systems: The system error 165 will appear on the display. Insert your Reference Disk and re-configure your system for the ImageAccel Display Controller. * * * Section 5 - Micro Channel Configuration The Hardware Installation section above steps you through the hardware installation procedure.

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.
