Important hints for the installation:
=====================================

1.) Do not try to use the miro Windows 3.x drivers under Windows 95.
    If you have done so already or tried to do it, make sure that all
    old miro Win 3.x drivers and entries in the SYSTEM.INI file have been
    removed.
    
    
2.) If you use a miro monitor or a multifrequency monitor,
    we recommend you to use the Monitor.inf file provided on this installation
    CD. Using the Monitor.inf file ensures that you use specially suited 
    monitor parameters. In the "Display Properties Window", select 
    "Change Display Type". Click "Change" to go to the monitor selection window.
    Click the "Have Disk" button and "Browse" to go to a file selection window. 
    Select the installation CD to change to the installation directory
    for miroMEDIA 3D. The mirodisp.inf and miromon.inf files are automatically
    entered. Click "OK" to go the miroMONITOR selection list. 
    Select your monitor. 

    Hint:    Please do not try to boost your monitor performance by selecting
             values which exceed the monitor´s characteristics. In doing so,
             you will damage your monitor. miro does not take on liability 
             in such cases.                                     

    Please make sure that your Win95\INF directory does not include old OEM*.INF 
    monitor files. This INF subdirectory cannot be listed by typing the  
    DIR command but by typing DIR /a. These INF files are ASCII files which 
    you can view using any editor. Before removing such files make sure that 
    you do not delete the wrong files. If you use the miro monitor files from 
    the original Windows 95 CD, please use the monitor files from this 
    installation CD.


3.) Each time you install graphics drivers Windows creates a new 
    OEM*.INF file in the Win95\INF subdirectory. Windows 95 does not remove, however,
    the old OEM*.INF files. Please make sure that only the current OEM*.INF
    files are contained in this directory and remove the old files. In doing so,
    you can avoid many problems.


4.) With the current Windows 95 version it may happen that  Windows 95 starts with 
    an error message (only 16 colors are offered) after installing
    miroMEDIA 3D. In this case, Windows 95 does not recognize the S3 Virge processor. 
    After installing the miro software this will not happen again.
    
    If it is however not possible to set the resolution and the number of colors
    correctly, you may use the miroTool kill3d.exe.
    This tool resets your computer to the state it was in before the installation 
    of the graphics hardware. After restarting Windows you can install your 
    graphics hardware as described above.

    Please only use the kill3d.exe program if it is absolutely necessary. 
    It is no substitute for the standard deinstall program which is located in the 
    miroMEDIA 3D program group.                                 


5.) If you have to update the drivers or to reinstall the software, remove the
    old miro software using the deinstall program. Before deinstalling all system files
    close the miroPINBOARD.    




LIMITATIONS
==========================================================================
In general, this graphics board does not support dual-screen configurations 
(Twinface) together with other graphics boards!!!


640x480         If you cannot switch to TV mode in this resolution, use the
                miroPINBOARD to enable TV Underscan.

miroSCREEN      Do not use this tool with fixed-frequency monitors. Do not adjust
ADJUST          image sizes and positions which deviate too much from the default 
                settings.
                You cannot use miroSCREEN ADJUST together with MPEG or TV output.

                While miroSCREEN Adjust is enabled, avoid changing the resolution 
                with miroPINBOARD or Windows95.

                It is not possible to change the image size with miroSCREEN Adjust
                under VGA2TV. You can, however, adapt the image size to your TV set.
                Extreme image positions result in distortions. Only use 
                miroSCREEN Adjust in the TV mode if your TV image is not centered 
                correctly.   

DirectX         You will be notified by a DirectX application that the used driver
                has not been tested with DirectX.
                When you are requested if you want to replace the driver by a tested 
                one, please answer NO.
                After having installed games under Windows 95, check if the miro driver
                is still active after restarting the system.    
                If not, enable or install the driver again.


Xing! Player    If you want to output an MPEG movie on a TV compatible device,
                first start MPEG on your computer monitor and then switch to 
                TV output. In addition the hardware acceleration in the XING Setup
                should be turned off.
                Do not use the virtual TV screen during playback.
                
                        

AVI & TV        If you want to play back an AVI movie in the full-screen mode on TV,
                enable VGA2TV under DOS.

Windows 3.x     miroMEDIA 3D is the first graphics hardware generation which is adapted 
                with its wide function range to a special system environment that is 
                Windows95 because Windows 95 is the first operating system which
                integrated the "DirectX" concept. In future, WindowsNT is possibly
                the next system which integrates "DirectX".
                
                For this reason, no Windows 3.x drivers are provided for miroMEDIA 3D.
                In case you need to use Windows 3.x anyway, you can download 3.x drivers
                via the miroBBS system or the internet.

Windows NT      see Windows 3.x

VGA2TV          using VGA2TV (see manual) and switching to the DOS fullscreen box
                it may appear a wrong char set. Type "mode co80" to get the correct 
                80x25 text mode.


Other limitations
=========================================================================

miro Computer Products AG always endeavors to support a wide range of languages.
Because not all manufacturers share this opinion, the "Xing!" Player
and "DirectX" is only supplied in English.
