Installation of miro drivers for Windows95:

Attention: Please don't try to install the miro drivers by running the
           install.exe program. Use the 'change display properties' from
           your control panel.

To install the miro drivers, proceed as follows:

* If you have not done so already, start your computer
* Open the Control Panel
* Click on Display
* Click the Settings folder
* Select Change Display Type... .The Change Display Type windows appears.
  Here you can change the graphics board and the monitor type.
* To select another graphics board, click on the "Change" button.
* Click "Have Disk..." To specify the disk drive from which you install 
  the drivers: default is drive a:\.
  Now there will be displayed the following model either
  "miro S3 Graphicadapter/PCI", or  "miro S3 Graphicadapter/VLB".
  In case both options will be displayed, please select the model which 
  is corresponding to your miro graphics adapter and click "ok". 
  The computer is restarted. After the restart the new resolutions are 
  available.





In case of problems please watch the following hints:

1.) In case Windows 95 doesn't start VLB computers, you can change the base-
    address for the linear memory adressing:

        System.ini:
        [Display]
        LinBase=<Addresse>

        i.e. 40320, or 60000

2.) For video graphics boards (Video 20SV, Video 40SV, Video 20SD, Video 40SV
    ergo) you can switch the hardware scaler off or improved.
    The entry are as follows:

        System.ini
        [Display]
        VideoStretch=<Value>

    Standardvalues:
    greatest security            : 257
    best video + security        : 259
    best optic + security        : 771
    greatest performance         : 261  <standard>
    best optic + performance     : 775

    The Value can be calculated as follows:
      [0 / 1]   for DIB scaling by hardware            [off / on]
    + [0 / 2]   for DIB interpolation by hardware      [off / on]
    + [0 / 4]   for DIB scaling parameteradaption      [off / on]
    + [0 / 256] for DDB scaling by hardware            [off / on]
    + [0 / 512] for DDB interpolation by hardware      [off / on]

3.) A DIB-engine driver is not usable for Video for Windows, but the
    optimized drivers can be fully used, if the Pinboard will set the 
    entries depending on the selected display mode in the Win.ini file.

    -> If possible start the Pinboard always starting Windows 95. The Pinboard
       will correct the entries of Video for Windows automaticly. 


4.) Using the miro Pinboard it could happen that, the switching from the
    virtual modes into the real modes doesn't work at once. In this case we
    recommend to switch first into the real mode resolution (640 x 480) and
    after this into a higher resolution.


5.) For the miroCRYSTAL 20SV the highest resolution of 1408 x 1024 in 8 bit is in
    Windows 95 at this time not available. This resolution will be available
    with the next driver update. t couls happen that a resolution will be offered
    in the Controlpanel, but you can't switch to this resolution. This means
    Windows 95 will fall bach to the earlier resolution.

6.) During the installation of a miroVIDEO 20SD in Windows 95 it could happen
    that both busadapter versions will be displayed. Make sure that you select
    the right businterface, that means either PCI, or VLB, depending of the bus-
    interface of your miro graphics board. Otherwise the miro graphics board can't
    be installed for Windows 95 and the drivers doesn't work.
