2.2.) Hardware installation

  Install your graphics board as described in the Hardware Manual
  supplied with your board. To use miroTWINFACE with two monitors
  having different technical data, connect the monitor with the
  lower resolution to the daughterboard. Connect the second monitor
  to the basic board. If you have two monitors with identical
  technical data, you do not have to connect them as described
  above. The monitor connected to the daughterboard displays the
  boot messages and the fullscreen DOS prompt. Make sure that DIP
  switch 2 is not set to ON.

  It is assumed that the monitor connected to the daughterboard
  is located on the right-hand side of your desktop and the
  monitor connected to the basic board on the left-hand side.
  This allocation can be redefined as described under 2.4.d).
  We recommend this arrangement, however, for monitors with
  different technical data, because then the icons for minimized
  programs are always located at the bottom on the left-hand
  side in the visible screen area.


2.3.) Driver installation

  It is required that you have installed Windows NT 4.0 with a
  graphics driver for your VGA board.

  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 "Display Type" window offers an overview of the currently
     active Display Driver. Please activate the "Change..."-button.

  e) In the "Select Device" 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 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) The titles consists of the name of your graphics board or your
     miroTWINMODULE which is assigned to the left/right monitors.

  d) If the boards are not assigned to the correct monitor, you
     can change this setting using the "Boot messages on left
     monitor" / "Boot messages on right monitor buttons. Select
     the monitor on which the boot messages appeared. After
     changing the setting, the titles are updated according to
     2.4.c). Also, the resolution list may change according to
     2.4.f).

  e) Select 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.

  f) After a short while you see the "Available Resolutions" list
     which gives you an overview of all resolutions supported by
     your monitor and the horizontal and vertical refresh rates.
     Please make sure that you do not select a horizontal scan
     frequency which is higher than the horizontal scan frequency
     of your monitor.

  g) To avoid loading the miroTWINFACE driver, press the "disable
      miroTWINFACE" button. If you disabled the "Disable current
      driver" button, the driver running before (e.g. miroCRYSTAL
      (single-screen) ) or the VGA driver is activated.

  h) To confirm your selection, click "OK".

  i) 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.

  j) 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.).

  k) Instad of proceeding as described under h), you can abort the
     tool by pressing the "Cancel" button. In this case, the settings
     you made will not be enabled.

  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.
  If you disabled the miroTWINFACE driver under 2.4.g), the
  miroMONITOR-Select program for the single-screen operation receives
  another button which activates miroTWINFACE. For the single-screen
  and the dual-screen operation the monitors have to be configured
  individually. There is no synchronisation between both installations.


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 your
     board and your monitor support and the number of colours
     and frequencies. 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 resolution of the basic board. If this resolution
     is higher than the maximum vertical resolution of the
     daughterboard, 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. The
     selected frequency refers to the monitor connected to the
     basic board. Detailed information for both monitors you will
     receive from the "miro Monitor Select" program.

  d) You can also use the "Desktop area" slider, the
     "Color Palette" and the "Refresh Frequency" windows 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/frequency 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 daughterboard.)
     - 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) You can restart the computer immediately by clicking "Restart Now"
     in the "Display settings change" window. You can also click the
     "Dont Restart Now" button to go back to the "Display type" window.
     To close this window click "Close". To close the "Display settings"
     window click "OK". Use the Program Manager to restart the system.

  h) After the restart the new resolution is active.

  i) 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.

  The "Font Size" window allows you to select another font size
  (see d)). If you have not installed the fonts of the selected
  size, you are requested to insert the installation disk under
  A:\. Overwrite the default with the drive letter of you CD drive
  and enter the path \i386. Insert the Windows NT Version 4.0 CD
  in your CD drive so that the required files can be copied to your
  hard disk.


2.6.) miro Video Address (Control Panel extension)

  To accelerate the image output even more, activate the linear
  video addressing function. For this purpose an extension of the
  Control Panel is installed during the installation. Open the
  Control Panel Program and click the "miro Video Address" icon
  to configure the linear video address,

  PLEASE NOTE:
  Keep in mind that problems may occur with motherboards which
  do not decode the addresses completely and in case of address
  conflicts with other memory-mapped expansion boards or with
  the main memory.

  PLEASE NOTE:
  For the driver for Windows NT 4.0 and a computer with PCI bus
  your system activates this option automatically. If any problems
  occur with your motherboard (e.g. older motherboards with PCI
  bus and Vesa Local bus), disable this option. All other
  adjustments of this tool will be ignored by the driver.

  Use the "Linear Video Addressing enabled" and the
  "Linear Video Addressing disabled" buttons to switch the
  linear video addressing function on/off:

  - "Linear Video Addressing enabled" switches this option on.
    Then the video memory of the graphics board is unsegmented
    and can be accessed by the display driver under the address
    specified under "Physical address".

  - "Linear Video Addressing disabled" switches this option off
    (default setting).

  The linear video address is specified under "Physical address".
  This address can be overwritten with a hexadecimal value. Make
  sure that the new address is aligned with 8 MB (example of
  sequence of increasing addresses: 7400.000 - 7480.000 - 7500.0000).
  (Default setting: fe00.0000)

  Use the arrow buttons beside the display window to increase /
  decrease the video address in 8 MB steps.

  The "Reset" button enables the default settings.

  Confirm your settings by clicking "OK" and close the
  "configuration of linear video address". The settings take
  effect after the computer has been restarted. If the address
  you entered is not aligned correctly, you cannot close the
  window using the "OK" button. Correct the setting or click
  "Cancel" to abort.

  If problems occur with the display driver when restarting
  the computer, start the system with another driver as
  described under 2.3) and switch the linear video
  addressing function off.

  PLEASE NOTE:
  The "miro Video Address" icon is only available in the "Control Panel"
  program, if a driver installed from this disk is currently active.


2.7.) Positioning windows

2.7.1.) through Windows NT 4.0

  Windows NT 4.0 has the capability to align windows.

  When clicking the Maximize button the window is maximized to
  a size which is determined by the virtual resolution of the
  smaller monitor which is connected to the base board. Maximized
  and normally sized windows can be moved independently of each
  other, the system always remembers their last position. Dialog
  boxes appear on one of both monitors.

  By default, this option is switched off. It can be switched on
  as described under 2.7.3.).

  NOTE:
  In case of incompatibilities with apllications you use, you
  cannot use this option.


2.7.2.) miroTWINFACE control - Program for positioning windows

  Along with the miroTWINFACE drivers, a program for controlling
  the window positions is copied to your hard disk. This program
  extends the possibilities for positioning windows the driver
  offers. When this program is active, dialog boxes, which
  otherwise appear on both screens. appear on the screen where
  the mouse cursor is located. When clicking on the Maximize
  button, the window is maximized on the screen, where the
  mouse cursor is currently located.

  Add the "MTWINCON.EXE" program which is located in the
  "WINNT\SYSTEM32" directory using the Drag and Drop function
  of the Explorer to one of your program groups. If you
  include the program in the Autostart group, the program is
  active immediately after you have logged in. After the program
  has been started, it is available as an icon on your desktop.
  For information on how to configure miroTWINFACE control, refer
  to 2.7.3.). To close the program, select the "Close" command
  in its system menu or log out.

  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 apllications
  you use, you cannot use miroTWINFACE control.


2.7.3.) 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).

  To configure the positioning of the dialog boxes, click on the
  "Dialog alignment" button (default = off).

  The "Alignment by System" button lets you switch on the Windows
  NT 4.0 alignment function (default = off).

  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".

  If you changed the "Alignment by System" option, you can restart
  the system by pressing the "Restart Now" button in the "Alignment
  Settings Change". You can also go back to the "Control Panel"
  program by pressing the "Dont restart now" button. Restart the
  system using the Program Manager.

  NOTE:
  You can also use both options: the Windows NT 4.0 and the
  miroTWINFACE control alignment. In case of incompatibilities
  with other applications, one or both options cannot be used
  available.


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 File Manager to delete the display driver
  (extension .DLL) under \WINNT\SYSTEM32 and the
  miniport driver (extension .SYS) and the configuration
  files (extension .INI) under \WINNT\SYSTEM32\DRIVERS.


4.) In case of problems

  In case of problems with the VGA DOS box in the
  fullscreen mode ask your dealer or miro for an update
  of the BIOS-ROM. In some cases an unsynchronized image
  may stabilize by switching between the window and the
  fullscreen mode of the VGA DOS box.

  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.


4.) 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.
