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

1.) Don't try to use former miro Windows 3.xx drivers for Windows 95.
    In case you tried to use these drivers make sure that all former 
    miro Windows 3.xx drivers and entries in your SYSTEM.INI file are removed. 

    In the SYSTEM.INI you have to remove the complete entries in the section
    [928.drv], [Twin.right] and [Twin.left]. Delete the following files in Win95 
    if available:

    Del \\OEMMAGS4.*
    Del \\OEMRAIN.*
    Del \\OEMCR32S.*
    Del \\OEMCR24S.*
    Del \\OEMCR16S.*
    Del \\OEMC16SI.*
    Del \\OEMCR8S.*
    Del \\OEMC10SD.*
    Del \\OEMC20SD.*
    Del \\OEMC20SV.*
    Del \\OEMC40SV.*
    Del \\OEMMAG40.*
    Del \\OEMMAG20.*
    Del \\OEMC20TW.*
    Del \\OEMBIBO*.*
    Del \\MAGS4*.DRV
    Del \\RAIN*.DRV
    Del \\CR32S*.DRV  
    Del \\CR24S*.DRV
    Del \\CR16S*.DRV
    Del \\C16SI*.DRV
    Del \\C8S*.DRV
    Del \\1SD*.DRV
    Del \\C20SD*.DRV
    Del \\C20SV*.DRV
    Del \\C40SV*.DRV
    Del \\M20*.DRV
    Del \\M40*.DRV
    Del \\TW10*.DRV
    Del \\TW20*.DRV
    Del \\TWIN.DRV
    Del \\OCTO.MON
    Del \\OCTOVGA.*
    Del \\MAGIC_S4.BMP
    Del \\RAIN_WIN.BMP
    Del \\MINFO.TXT
    Del \\MWINTOOL.INI
    Del \\MSUP*.*
    Del \\MONSEL.*
    Del \\VIRTDLL.DLL
    Del \\MFONTCOM.EXE
    Del \\MIROSCOP.EXE
    Del \\MIROHOOK.DLL
    Del \\MSCOPE*.HLP
    Del \\MPWRSAVE.SCR
    Del \\TWIN*.*
    Del \\MTINT*.*
    Del \\MSIZE*.*
    Del \\WSIZER.*
    Del \\WADJUST.*
    Del \\MIROLOGO.RLE

    Also delete the miroWINTOOL program group and the icons 
    on your Windows95 desktop!!!

2.) In case you are using a miro monitor or a common model please install
    a new monitor file. This installation disk contains this monitor.inf file.
    Make sure that there is no older OEM*.INF monitor file in your Win95\INF
    subdirectory. This subdirectory is hidden, but you can make it visible
    by entering the DIR /a command. All INF files are ASCII files and you
    can read these files with every editor, so please make sure that you
    don't delete required INF files. Look into the file before you delete it!!!
    If you are using the miro monitor files of the original Windows 95 CD,
    please use the miro monitor file of this disk.

3.) Every time you install new display drivers in Windows 95 a new OEM*.INF 
    file will be copied into your WIN95\INF subdirectory. Windows 95 doesn't 
    remove the old *.inf files. Make sure that only the specified OEM*.INF
    file is available. This could prevent many problems!

4.) Remember that all miroVIDEO graphics boards (VIDEO 20SD, VIDEO 20SV,
    VIDEO 22SD, VIDEO 40SV ergo) need an IRQ.

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

        System.ini:
        [Display]
        LinBase=<Address> (MB)

        i.e. 64, 128, or 192

6.) For miroVIDEO graphics boards (VIDEO 20SD, VIDEO 20SV, 
    VIDEO 22SD, VIDEO 40SV ergo) you can switch the hardware
    scaler off or improved.
    The entries are as follows:

        System.ini
        [Display]
        VideoStretch=<Value>

    Default values:
    greatest security            	   : 257
    best video + security                  : 259
    best display quality + security        : 771
    greatest performance                   : 261  <standard>
    best display quality + 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 parameter adaption     [off / on]
    + [0 / 256] for DDB scaling by hardware            [off / on]
    + [0 / 512] for DDB interpolation by hardware      [off / on]

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

    ->If possible, start the miroPINBOARD always starting Windows 95. 
      The miroPINBOARD will correct the entries of Video for Windows 
      automatically. 


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


9.) If it happens that both bus adapter versions will be displayed. Make sure 
    that you select the right bus interface  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 
    won't work. 

10.)Combination of miroVIDEO DC20 and S3 based graphics boards in mainboards 
    with AWARD BIOS:
    868 and 968 S3 chips etc. need a linear adress area of 64MB under Windows 95. 
    The current AWARD BIOS reserves an address area of 32MB for this graphics 
    boards only. In case the memory area of the miroVIDEO DC20 is located directly 
    after the memory area of the S3 based graphics board make sure that there is 
    a memory area of 64MB between the graphics board and the miroVIDEO DC20 
    memory area. You can change the memory area in Windows 95 in your System 
    Control Panel in the Device Manager in the Resources tab.
   
    AWARD has solved this problem with a BIOS update. This BIOS Update can be 
    loaded down from the BBS of the motherboard manufacturers.	

11.)During the installation of Lotus Smart Suite 4.0 under Windows 95 the 
    background bitmap of Lotus won't be displayed properly, but there are no 
    limitations using the functions of this software package. In the next 
    driver release this bug will be fixed.
