General information:

        To use a miroCRYSTAL graphics board the 02E8h address must 
        not be used. This address is used by COM4, and gameport 
        expansions, and by some network boards. In addition, you have 
        to deactivate the VGA on your motherboard (if there is a VGA).

        If the computer does not boot correctly (spec. with an
        EISA graphics board and an Adaptec EISA busmaster SCSI 
        controller 1742) or if the monitor select program does 
        not detect the installed graphics board, these are computer-
        specific problems. To solve these problems, activate ROM 
        shadowing for the Video BIOS, using the motherboard BIOS 
        setup or the corresponding Memory Manager option. For 
        MS DOS 6.0 change the CONFIG.SYS file in the following way:
        DEVICE=C:\DOS\EMM386.EXE ... ROM=C000-C800 ...
        Please also refer to your computer's manual or to the 
        MS DOS 6.0 manual.


Information on the installation:

        When using a miroCRYSTAL 10SD you should consider whether you 
        prefer an extremely high vertical scan frequency or a high 
        processing speed. As a compromise, select a 64 kHz monitor. 
        The resolution of 1024 x 768 pixels with 256 colors is then 
        realized with 75 Hz. This is due to the fact that the 
        miroCRYSTAL 10SD is equipped with DRAMs.

        If you installed a Windows network version, there may occur 
        problems resulting from the configuration. The miro software 
        has to be installed at the work place. The installation program 
        has to be able to copy drivers, applications, and configuration 
        files to the local Windows directory of the computer at the 
        work place. In addition, it is neccesary that the local files 
        SYSTEM.INI, WIN.INI, CONTROL.INI and MWINTOOL.GRP can be
        created/overwritten. With the help of the monitor-select-
        program each work place is adapted to its individual equipment 
        by entering specific data in the OCTO.MON and the three *.INI 
        files mentioned above.

        If you exchange your old graphics board by a miroCRYSTAL 
        graphics board or if you exchange one miro board by the other, 
        you should reconfigure Windows for VGA. In doing so, you avoid 
        that a wrong driver runs on your new graphics board when 
        starting Windows and that your system crashes. Install the 
        driver for the new board in the VGA mode.


Installation under Norton Desktop:

        If you use the Norton Desktop instead of the Microsoft 
        Program Manager, the miroWINTOOLS group (MWINTOOL.GRP) 
        which the installation program generates may not be 
        integrated in the Norton Desktop. To avoid this, start 
        the Program Manager (PROGMAN.EXE) as a symbol before 
        starting the installation program or integrate this 
        group manually in the Norton "Quick Access" group after 
        the installation. To do so, open the drive window containing 
        the Windows directory and the "Quick Access" window 
        and drag the MWINTOOL.GRP file from the drive directory 
        window to the "Quick Access" window. Also refer to your 
        Norton desktop manual.


Information on Windows:

        At the 640 x 480 resolution do not select the option 
        "TV overscan" with miroSUPERSCREEN.
        
        If the icons in one of your program groups are black (or you 
        get an error message concerning this), there are too many icons 
        in this group. Split this group up into smaller ones. This is 
        due to Windows and occurs with 65k/16.7 mill color drivers.

        With CorelDraw you can accelerate the polygon output consider-
        ably by entering in the CORELDRW.INI file in the section
          [CDrawConfig]
            UseClippingForFills=0
       
        If key commands are not accepted after switching to the MS-DOS 
        prompt, press the <ALT> key. Then, Windows checks the state of 
        this key and the following key commands will be accepted.

        In the SYSTEM.INI file in the [386Enh] section, you should add 
        EMMEXclude=A000-FFFF. Then, the whole adapter address range is 
        excluded from the scanning of free memory blocks.

        miroSCOPE has to be closed before calling the MS DOS prompt.
        If you don't do so, you can not switch from the full-screen
        to the windowed mode by entering <ALT>+<RETURN>.

	With miroCRYSTAL 10SD PCI running Microsoft WORD for Windows with 
	Page Preview and selecting 2 Pages sometimes a General Protection 
	Failure occurs.
