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 3.51 with a graphics driver for your VGA board. PLEASE NOTE: If you dont't have installed Windows NT 3.51, first install it in VGA mode. Do not use the system supplied S3 driver. Continue the installation and install the driver after reboot of the system. 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 3.51. 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 your board and 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 (31 kHz VESA monitor: 640 x 480, 256 colours, 60 Hz). Go on with 2.4.) to select a monitor and with 2.5.) to change the resolution. If problems occur with the display driver when restarting the system, you can reselect the VGA driver by using the "Windows NT Version 3.51 [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" 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.

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 CRYSTALV.DLL under \WINNT35\SYSTEM32 and the miniport driver CRYSTALV.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. 5.) Special hint Please do not try to install drivers or system-relevant tools which are suited for Microsoft Windows 3.x or Microsoft Windows 95. Windows NT 3.51 does not support these drivers or tools. In the worst case, this may cause a system crash. - eof
