2.2.) Hardware installation

  Install your graphics board as described in the Hardware Manual
  supplied with your board.


2.3.) Driver installation

  It is required that you have installed Windows NT 3.5 with a
  graphics driver for your VGA board.

  a) In the "main" group start the "Control Panel" program.

  b) Start the "Display Tool" to select/change the video display.

  c) In the "Display Settings" window click the "Change Display Type"
     button.

  d) In the "Display Type" window you get information on the current
     display driver. Click the "Change" button.

  e) The "Select Device" window offers an overview of all display
     drivers supplied with Windows NT 3.5. Click the "Other" button.

  f) In the "Install From Disk" window you are requested to insert
     the installation disk "A:\". If necessary, overwrite the default
     selection. Click "OK" to confirm.

  g) The "Select Device" window appears again. At the end of the
     display driver list there is also the driver for your miro board.
     Select the "miroCRYSTAL / miroVIDEO (single screen)" driver for 
     all boards supported by this installation disk. Click the "Install" 
     button. Confirm the following warning.

  h) If you had already installed the driver, you are asked whether
     you want to install the old or the new driver. Start the
     installation of a new driver by clicking the "New" button.

  i) You are requested again to insert the installation disk
     under A:\. If necessary, overwrite the default. To confirm the
     installation, click the "Continue" button. When the message about
     a successful installation appears confirm. Confirm the message
     telling you that the driver is only available after restarting
     the computer.

  j) 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.

  k) After the restart the driver which has just been installed is
     active with the lowest resolution (640 x 480, 256 colours, 60 Hz).
     To change this setting, proceed with 2.4.).

  If problems occur with the display driver when restarting
  the system, you can reselect the VGA driver by using the
  "Windows NT Version 3.5 [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 this does not help either, use the Windows-NT-setup-disk/-CD
  and the "Emergency Repair Disk" to repair your system. The
  "Emergency Repair Disk" should include a configuration with a
  VGA driver "640x480, 16 colors" because your system runs properly
  with this driver in any case. To repair your system select the
  "Inspect configuration registry" and "SYSTEM (System Configuration)"
  options only.

  If your system uses another display driver, you need the installation 
  disk to enable the "miroCRYSTAL / miroVIDEO" driver again. You can, 
  however, use the driver already installed on your hard disk by 
  clicking the "Current" button (see h)).


2.4) miro Monitor Select - Control Panel extension

  a) Start the "Control Panel" program from the "main" group.

  b) To select a monitor, start the "miro Monitor Select"-Tool.

  c) The title is the name of your graphics board.

  d) 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.

  e) 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.

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

  g) 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 
     Program Manager.

  h) After the restart the selected monitor is 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. To change the resolution, proceed with 2.5.).

  i) Instad of proceeding as described under f), 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.


2.5.) Changing the resolutions

  a) In the "main" group 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.

  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 the monitor?
     - Is the correct resolution specified?
     - Are the arrows in the testscreen margins visible?
     - 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 3.5 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. This option is not available for ISA boards.

  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 to defaults" 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.


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 \WINNT35\SYSTEM32 and the
  miniport driver (extension .SYS) and the configuration 
  files (extension .INI) under \WINNT35\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.

  "TWIN" boards and miroTWINFACE are not yet supported
   by this diskette.
