miroCYSTAL 3D
============


Important hint for DC30 and PCTV users:
=======================================
The recent introduction of Microsoft´s DirectX technology has made it
possible to use the free memory of a graphics board for an overlay by
transferring the video data directly via the PCI bus. In addition, 
DirectX introduces many new functions which are especially suited for 
computer games.

New technologies, however, may also lead to problems. On some earlier
systems the combination of DirectX-3, the optimized miro drivers, and 
the DC30 board may cause trouble.
For this reason, miro has decided to offer two driver concepts: 
the optimized ones and drivers which have been especially designed for 
Digital Video applications.
For this reason digital Video users (DC20, DC30, PCTV) will find a 
special Digital Video driver version in the \Disksets\DVEDRV\ directory
on the installation CD.


This CD contains the following components in addition to the system software
miroCRYSTAL 3D:

        Windows 95						
        ----------
	1. DirectDraw compatible Display Driver      
	2. Microsoft DirectX
        3. Microsoft DirectVideo

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 miroCRYSTAL 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
    miroCRYSTAL 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 miroCRYSTAL 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!!!



miroSCREEN      Do not use this tool with fixed-frequency monitors. Do not
                adjust image sizes and positions which deviate too much from
                the default settings.
                
Adjust          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     miroCRYSTAL 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  miroCRYSTAL 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 "ActiveMovie"
Player and "DirectX" is only supplied in English.
