                    ===========================

General information:

        To use a miroCRYSTAL graphics board the 02E8h address must 
        not be used. This address is used by COM3, 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:

        If you have problems to install from diskette you can also 
        copy them into a directory on your hard disk.Then, assign a 
        drive letter to this directory with the SUBST command. Please 
        refer to the MS DOS manual.

        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.

        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 some cases lines remain on the desktop. To avoid this, enter
        VXPBLT=1 in the SYSTEM.INI file under [928.drv].

        In exceptional cases additional expansion boards may cause that 
        the graphics driver does not function properly. 
	For example network problems, modem problems or a sticky mouse cursor.
	In these cases enter the line FIFO=1 under [928.drv] in the 
	SYSTEM.INI file.

        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 some PCI systems, especially the old ones compatible with 
        PCI Rev. 1.x, bus disturbances may occur in conjunction with
        miroCRYSTAL 20SD. To adapt the graphics board to the PCI bus 
        speed, enter
          PCIHIGH=0
        in the SYSTEM.INI file under [928.drv]. You recognize these 
        disturbances by individual faulty pixels.
        
        To achieve optimal performance under MS Video for Windows,
        change the driver parameters in the WIN.INI file in the
        [drawdib] section to 
	"5,0,0,0" 	fuer 8  Bit
	"5,5,5,5" 	fuer 15 Bit
	"5,5,5,5" 	fuer 16 Bit
	"5,0,5,5" 	fuer 24 Bit 
                
        Some applikations like
		PC Paintbrush 1.0
		CCAM
		IRON HELIX
		Quick Time Picture Viewer
	use not Windows komform bitmaphandling.       
        In these cases the bitmaps look chopped.
        Please add under [928.drv] in the SYSTEM.INI file the line
        DDBCACHE=0
        
        Do not use miroSCREEN ADJUST with fixedfrequenzy monitors.
        Please do not change the adjustments too far, because this can
        destroy your monitor.

	It is not recommended to use the miroSCREEN-Adjust tool together with 
	a fixed-frequency monitor. If you change the image size, the video 
	mode might not comply with the monitorīs characteristics. Do not change
	the monitorīs size and position in a way that the settings differ too 
	much from the default setting, because then your monitor might be damaged.

	When the message "This is no miro driver" appears, no suitable miro 
	graphics driver is active. miroPINBOARD does not support any resolution 
	with 16 colors  and any TrueColor for 1 MB miro graphics boards.

        If you get a parity error or a page fault, please change th folowing
        line in the system.ini in the [928.drv] sektion
        LinBase=1024

	With paintbrsuh sometimes small freehand lines may have wrong width.
