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 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.

     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 "mirosing.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.

  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.

  a) By using the Icon "My Computer", you can start the "Control Panel"
     program.

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

     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.).

     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.

     the "Test" button and confirm.

     in the "Display settings change" window. You can also click the
     "Don´t Restart Now" button to go back to the "Display type" window.

     window click "OK". Use the Program Manager to restart the system.

  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.



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 \WINNT40\SYSTEM32, the miniport
  driver (extension .SYS) under \WINNT40\SYSTEM32\DRIVERS 
  and the configuration files (extension .INI) under 
  \WINNT40\SYSTEM32\DRIVERS\MIRO\TIMING.


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 box 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.
