Hardware installation Install your graphics board as described in the Hardware Manual supplied with your board. 2.3.) Driver installation It is required that you have installed Windows NT 3.5 with a graphics driver for your VGA board. a) In the "main" group start the "Control Panel" program. b) Start the "Display Tool" to select/change the video display. c) In the "Display Settings" window click the "Change Display Type" button. d) In the "Display Type" window you get information on the current display driver. Click the "Change" button. e) The "Select Device" window offers an overview of all display drivers supplied with Windows NT 3.5. Click the "Other" button. f) In the "Install From Disk" window you are requested to insert the installation disk "A:\". If necessary, overwrite the default selection. Click "OK" to confirm. g) The "Select Device" window appears again. At the end of the display driver list there is also the driver for your miro board. Select the "miroCRYSTAL / miroVIDEO (single screen)" driver for all boards supported by this installation disk. Click the "Install" button. Confirm the following warning. h) If you had already installed the driver, you are asked whether you want to install the old or the new driver. Start the installation of a new driver by clicking the "New" button. i) You are requested again to insert the installation disk under A:\. If necessary, overwrite the default. To confirm the installation, click the "Continue" button. When the message about a successful installation appears confirm. Confirm the message telling you that the driver is only available after restarting the computer. j) You can restart the computer immediately by clicking "Restart Now" in the "Display settings change" window. You can also click the "Donīt Restart Now" button to go back to the "Display type" window. To close this window click "Close". To close the "Display settings" window click "OK". Use the Program Manager to restart the system. k) After the restart the driver which has just been installed is active with the lowest resolution (640 x 480, 256 colours, 60 Hz). To change this setting, proceed with 2.4.). If problems occur with the display driver when restarting the system, you can reselect the VGA driver by using the "Windows NT Version 3.5 [VGA mode]" option in the boot menu. If this doesn`t solve the problem use the "last good menu" option to reselect the old configuration. If this does not help either, use the Windows-NT-setup-disk/-CD and the "Emergency Repair Disk" to repair your system. The "Emergency Repair Disk" should include a configuration with a VGA driver "640x480, 16 colors" because your system runs properly with this driver in any case. To repair your system select the "Inspect configuration registry" and "SYSTEM (System Configuration)" options only. If your system uses another display driver, you need the installation disk to enable the "miroCRYSTAL / miroVIDEO" driver again. You can, however, use the driver already installed on your hard disk by clicking the "Current" button (see h)). 2.4) miro Monitor Select - Control Panel extension a) Start the "Control Panel" program from the "main" group. b) To select a monitor, start the "miro Monitor Select"-Tool. c) The title is the name of your graphics board. d) Select your monitor from the "Monitor" list. If your monitor is not listed, select the monitor from the "Multi Frequency" monitors with the frequency which comes close to the frequency of your monitor. e) After a short while you see the "Available Resolutions" list which gives you an overview of all resolutions supported by your monitor and the horizontal and vertical refresh rates. Please make sure that you do not select a horizontal scan frequency which is higher than the horizontal scan frequency of your monitor. f) To confirm your selection, click "OK". g) In the "Monitor Settings Change" window you can restart your computer immediately by pressing the "Restart Now" button. You can also click the "Don't Restart Now" button to get back to the "Control Panel" program. Restart the system using the Program Manager. h) After the restart the selected monitor is active. If the resolutions and refresh rates differ from the settings of the previous monitor, the system will notify you. Then, the 640 x 480 resolution with 256 colors and 31 kHz / 60 Hz is enabled. To change the resolution, proceed with 2.5.). i) Instad of proceeding as described under f), you can abort the tool by pressing the "Cancel" button. In this case, the settings you made will not be enabled. PLEASE NOTE: The "miro Monitor Select" icon is only available in the "Control Panel" program, if a driver installed from this disk is currently active. 2.5.) Changing the resolutions a) In the "main" group start the "Control Panel" program. b) Start the "Display Tool" to select/change the video display. c) The "List All Modes" button lists the resolutions your board and your monitor support and the number of colours and frequencies. Double-click to select a resolution. d) You can also use the "Desktop area" slider, the "Color Palette" and the "Refresh Frequency" windows to select a resolution. Keep in mind that the settings are interdependent. If you select an invalid setting, the other options change so that a valid setting is restored. e) To check the selected resolution in a testscreen, click the "Test" button and confirm. - Is the selected resolution/frequency displayed on the monitor? - Is the correct resolution specified? - Are the arrows in the testscreen margins visible? - Are the coloured and the hatched areas displayed correctly? f) After five seconds the testscreen disappears and you see the workspace again. If the resolution on the testscreen is OK, confirm the "Testing Mode" window with "Yes". g) You can restart the computer immediately by clicking "Restart Now" in the "Display settings change" window. You can also click the "Donīt Restart Now" button to go back to the "Display type" window. To close this window click "Close". To close the "Display settings" window click "OK". Use the Program Manager to restart the system. h) After the restart the new resolution is active. i) If you do not like the resolution, click "No" in the "Testing Mode" window. After another message has appeared, you are back in the "Display Settings" window. Select another resolution and continue with e) or close the Display Tool by clicking the "Cancel" button. The "Font Size" window allows you to select another font size (see d)). If you have not installed the fonts of the selected size, you are requested to insert the installation disk under A:\. Overwrite the default with the drive letter of you CD drive and enter the path \i386. Insert the Windows NT Version 3.5 CD in your CD drive so that the required files can be copied to your hard disk. 2.6.) miro Video Address (Control Panel extension) To accelerate the image output even more, activate the linear video addressing function. For this purpose an extension of the Control Panel is installed during the installation. Open the Control Panel Program and click the "miro Video Address" icon to configure the linear video address, PLEASE NOTE: Keep in mind that problems may occur with motherboards which do not decode the addresses completely and in case of address conflicts with other memory-mapped expansion boards or with the main memory. This option is not available for ISA boards. Use the "Linear Video Addressing enabled" and the "Linear Video Addressing disabled" buttons to switch the linear video addressing function on/off: - "Linear Video Addressing enabled" switches this option on. Then the video memory of the graphics board is unsegmented and can be accessed by the display driver under the address specified under "Physical address". - "Linear Video Addressing disabled" switches this option off (default setting). The linear video address is specified under "Physical address". This address can be overwritten with a hexadecimal value. Make sure that the new address is aligned with 8 MB (example of sequence of increasing addresses: 7400.000 - 7480.000 - 7500.0000). (Default setting: fe00.0000) Use the arrow buttons beside the display window to increase / decrease the video address in 8 MB steps. The "reset to defaults" enables the default settings. Confirm your settings by clicking "OK" and close the "configuration of linear video address". The settings take effect after the computer has been restarted. If the address you entered is not aligned correctly, you cannot close the window using the "OK" button. Correct the setting or click "Cancel" to abort. If problems occur with the display driver when restarting the computer, start the system with another driver as described under 2.3) and switch the linear video addressing function off. PLEASE NOTE: The "miro Video Address" icon is only available in the "Control Panel" program, if a driver installed from this disk is currently active. 3.) Deleting drivers Delete drivers you do not need anymore by enabling another driver using the Display Tool of the Control Panel program and by restarting the sytem afterwards. Then, use the File Manager to delete the display driver (extension .DLL) under \WINNT35\SYSTEM32 and the miniport driver (extension .SYS) and the configuration files (extension .INI) under \WINNT35\SYSTEM32\DRIVERS. 4.) In case of problems In case of problems with the VGA DOS box in the fullscreen mode ask your dealer or miro for an update of the BIOS-ROM. In some cases an unsynchronized image may stabilize by switching between the window and the fullscreen mode of the VGA DOS box. The VGA DOS boxs only supports the resolutions available for a 'standard VGA', e.g. display modes of up to 320x200 pixels with 256 colors or 640x480 pixels with 16 colors. If a DOS application tries to use a higher resolution, the VGA DOS box, or, in the worst case, the hole system might crash. "TWIN" boards and miroTWINFACE are not yet supported by this diskette. - eof
