NOTE: The drivers on the disk have been developed for "Windows NT Workstation Version 4.0" (build 1381). Compatibility with other versions of Windows NT version is not guaranteed. ATTENTION: 1. The current driver version supports no single frequency monitors, so never connect a single frequency monitor to one or both graphics boards. IN THE WORST CASE, THIS MAY DESTROY YOUR SINGLE FREQUENCY MONITOR. 2. If you use two monitors having different technical data: AFTER INSTALLATION, NEVER EXCHANGE THE MONITORS BY EXCHANGING THE CONNECTIONS TO THE GRAPHICS BOARDS. IN THE WORST CASE, THIS MAY DESTROY YOUR MONITORS. 1.) Disk contents 2.) miroTWINFACE dual-screen configuration 2.1.) Supported boards 2.2.) Hardware installation 2.3.)

During system start, the motherboard bios scans all PCI slots and assigns the first graphics board it finds as bootboard. The scan direction of PCI slots can vary form mainboard to mainboard, so it is not possible to determine the bootboard before you have installed the hardware. 2.1.) Supported boards 8 Bit (256 colors) / 16 Bit (65k colors) / 24 Bit (16,7M colors): - miroCRYSTAL VR4000 + miroCRYSTAL VR4000 ATTENTION: The current driver version is suited only for combinations of graphics boards mentioned above. Do not try to install another combination of graphics boards. IN THE WORST CASE, THIS MAY DESTROY YOUR HARDWARE. 2.2.) Hardware installation Install your graphics boards as described in the Hardware Manual supplied with your boards. Both graphics boards must be installed onto the same PCI-bussystem. It is assumed that the left monitor is connected to the bootboard. It could be necessary to exchange this assignment LATER (see 2.3) because the bootboard is unknown just now. ATTENTION: If you use use two monitors having different technical data: NEVER EXCHANGE THE MONITORS BY EXCHANGING THE CONNECTIONS TO THE GRAPHICS BOARDS. IN THE WORST CASE, THIS MAY DESTROY YOUR MONITORS. 2.3.) Driver installation It is required that you have installed Windows NT 4.0 with a graphics driver for your VGA board. If you have already installed one graphics board with the appropriate single driver, please continue at a), too. a) By using the Icon "My Computer", you can start the "Control Panel" program. b) Start the "Display-Tool". Switch to the "Settings" section. c) Please choose the "Change Display Type" button. d) The "Change Display" window offers an overview of the currently active Display Driver. Please activate the "Change..."-button. e) The "Select Device" window offers you an overview of all display drivers supplied with your Windows NT 4.0 Installation. Please select the "Have Disk..."-button. f) In the "Install from Disk" window, please choose the driver and directory containing your installation software. You can search your drivers by using the "Browse"-button. Only files with the filename extension ".inf" are displayed. The file you have to look for is named "mirotwin.inf". g) After selecting the proper file, you choose the installed graphics board from the "Change Display" window. Select your board and press "OK" or doubleclick the appropriate entry in the list. h) Select "YES" in the "Third-party Drivers" messagebox. The driver files are now being copyied to your harddisk. i) Close the "Display Type" and the "Display Properties" windows and reboot the computer. j) After the restart the driver which has just been installed is active with the lowest resolution (31 kHz VESA monitor: 640 x 480, 256 colours, 60 Hz). Go on with 2.4.) to select a monitor and with 2.5.) to change the resolution. If your Desktop is exchanged: a) Exchange the order of your monitors by exchanging them on your table. or b) Shut down your system. Switch your Computer off. Exchange the connections to your graphics boards. Restart your System. ATTENTION: In case you use two monitors having different technical data: AFTER SUCCESSFULL INSTALLATION ( 2.3) and 2.4)), NEVER EXCHANGE THE MONITORS BY EXCHANGING THE CONNECTIONS TO THE GRAPHICS BOARDS. IN THE WORST CASE, THIS MAY DESTROY YOUR MONITORS. NOTE: If problems occur with the display driver when restarting the system, you can reselect the VGA driver by using the "Windows NT Version 4.0 [VGA mode]" option in the boot menu. If this doesn`t solve the problem use the "last good menu" option to reselect the old configuration. If your system uses another display driver, you need the installation disk to enable the miro driver again. 2.4.) miro Monitor Select - Control Panel extension a) By using the Icon "My Computer", you can start the "Control Panel"-program. b) To select the monitors, start the "miro Monitor Select"-Tool. c) Choose "Boot messages on left monitor" or "Boot messages on right monitor" depending on which monitor the boot messages appeared. If you are not sure, you may restart the system with the "RESTART NOW"-Button. d) Select for both boards your monitor from the "Monitor" list. If your monitor is not listed, select the monitor from the "Multi Frequency" monitors with the frequency which comes close to the frequency of your monitor. e) To confirm your selection, click "OK". You can abort the tool by pressing the "Cancel" button. In this case, the settings you made will not be enabled. f) In the "Monitor Settings Change" window you can restart your computer immediately by pressing the "Restart Now" button. You can also click the "Don't Restart Now" button to get back to the "Control Panel" program. Restart the system using the taskbar. g) After the restart the selected monitors are active. If the resolutions and refresh rates differ from the settings of the previous monitor, the system will notify you. Then, the 640 x 480 resolution with 256 colors and 31 kHz / 60 Hz is enabled for both screens. To change the resolution, proceed with 2.5.). ATTENTION: When you reconfigure your system (e.g. exchanging the graphics boards, removing one graphics board, changing slot positions, exchanging monitors or monitor connections to the graphics boards) please select for BOTH monitors the "31KHz VESA monitor" BEFORE changing your hardware-configuration. After succesfull reconfiguration of your system, choose the appropriate monitors as described in 2.4). PLEASE NOTE: The "miro Monitor Select" icon is only available in the "Control Panel" program, if a driver installed from this disk is currently active. When you remove one of the installed graphic boards the appropriate miroMONITOR-Select program for the single-screen operation will be used. 2.5.) Changing the resolutions a) By using the Icon "My Computer", you can start the "Control Panel"-program. b) Start the "Display" tool to select/change the video display. c) The "List All Modes" button lists the resolutions and the number of colours your board and your monitor support. Frequencies are chosen automaticaly. Double-click to select a resolution. PLEASE NOTE: For miroTWINFACE for Windows NT version 4.0 the horizontal resolutions are added, the vertical resolution is the maximum vertical value of both boards. If this resolution is higher than the maximum visible vertical resolution of the second board, the remaining screen area is displayed virtually, the workspace can be moved by moving the mouse cursor toward the upper or the lower screen margin. d) You can also use the "Desktop area" slider and the "Color Palette" window to select a resolution. Keep in mind that the settings are interdependent. If you select an invalid setting, the other options change so that a valid setting is restored. e) To check the selected resolution in a testscreen, click the "Test" button and confirm. - Is the selected resolution displayed on both monitors? - Is the specified resolution the resolution of the visible screen area? - Are the arrows in the margins of the testscreen visible? (In the virtual mode the arrows are not visible on the monitor connected to the second board.) - Are the coloured and the hatched areas displayed correctly? f) After five seconds the testscreen disappears and you see the workspace again. If the resolution on the testscreen is OK, confirm the "Testing Mode" window with "Yes". g) Click the "OK" Button, the new resolution is active. h) If you do not like the resolution, click "No" in the "Testing Mode" window. After another message has appeared, you are back in the "Display Settings" window. Select another resolution and continue with e) or close the Display Tool by clicking the "Cancel" button. 2.6.) Positioning windows 2.6.1.) miroTWINFACE control - Control Panel Extension This extension is copied together with the "miro Monitor Select" extension. Open the Control Panel Program and click the "miroTWINFACE control" icon to configure miroTWINFACE control. To configure the positioning of maximized windows, select the "MAXIMIZE alignment" button (default = off). When this option is active, when maximizing a window, the window is maximized on the screen, where the mouse cursor is currently located. To configure the positioning of the dialog boxes, click on the "Dialog alignment" button (default = off). If active, dialog boxes are aligned on the screen, where the mouse pointer is currently located. To confirm, click "OK" and close the "configuration of miroTWINFACE control". Now, the selected settings are saved and will be used by every application which will be started. To abort the configuration, click on "Cancel". NOTE: Not all windows can be controlled by miroTWINFACE control. This phenomenon is inherent in the system and must not be regarded as a failure. In case of incompatibilities with aplications you use, you cannot use miroTWINFACE control. 2.7.) PanControl Tool If the vertical resolution on one board is higher than the maximum visible vertical resolution of the second board, the remaining screen area is displayed virtually. The workspace can be moved by moving the mouse cursor toward the upper or the lower screen margin. This behaviour can be enabled or disabled using the PanControl-Tool. For installation, create a shortcut to the file WINNT\SYSTEM32\DRIVERS\MIRO\TOOLS\Panctrl.exe. A doubleclick onto the shortcut will enable/disable panning if a virtual resolution is active. After system start or changing the resolution, panning is always activated. NOTE: It is possible to assign an arbitrary shortcut key to the PanControl Tool. Rightclick the shortcut and then click "properties". Click the "Shortcut" tab. In the "Shortcut Key" Box type the shortcut key. 3.) Deleting drivers Delete drivers you do not need anymore by enabling another driver using the Display Tool of the Control Panel program and by restarting the sytem afterwards. Then, use the Explorer to delete the display driver (CRYSTALV.DLL) under \WINNT\SYSTEM32, the miniport driver (CRYSTALV.SYS) under \WINNT\SYSTEM32\DRIVERS, and the configuration files (extension .INI) under WINNT\SYSTEM32\DRIVERS\MIRO\TIMING. The file userhint.exe should be deleted under WINNT\SYSTEM32\DRIVERS\MIRO\TOOLS. 4.) In case of problems The VGA DOS boxs only supports the resolutions available for a 'standard VGA', e.g. display modes of up to 320x200 pixels with 256 colors or 640x480 pixels with 16 colors. If a DOS application tries to use a higher resolution, the VGA DOS box, or, in the worst case, the hole system might crash. 5.) Special hint Please do not try to install drivers or system-relevant tools which are suited for Microsoft Windows 3.x or Microsoft Windows 95. Windows NT 4.0 does not support these drivers or tools. In the worst case, this may cause a system crash. - eof
