miroMEDIA 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 
miroMEDIA 3D:




        Windows 95

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!!!



miroSCREEN      Do not use this tool with fixed-frequency monitors.
ADJUST          Do not 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 NOTE: 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. I 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          When 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.
