It explaines how to setup the ELSA WINNER driver and how to check whether it was installed properly. For more information about how to configure an installed ELSA display driver refer to the Windows help or the help files shipped with the ELSA utilities. ------------------------------------------------------------------------ 2 List of files NOTE Not all of the files listed below can be used by your graphic adapters. Some utilities need especial adapter capabilities and hardware. The directory with the ELSA graphics driver for Windows NT contains the following files: DISK1 Identifier for the first disk DISK2 Identifier for the second disk DISK3 Identifier for the third disk ELSA.HLP ELSA help file ELSA.INF Script file for Microsoft setup program LIESMICH.TXT German version of the file README.TXT README.TXT The file you are reading SETUP.EXE Setup utility SETUP.INI Setup configuration file TXTSETUP.OEM Script file for text setup at boot time Machine-dependent files will be found in directories named named .\I386\, .\ALPHA\ or .\PPC\: graphics display drivers: WINNER.SYS Miniport driver WINNER.DLL Display driver WINNERMB.DLL Multi-Display driver ELSAOGL.DLL OpenGL driver utilities: Note: It is possible that not all subdirectories listed below are available or necessary for your graphics adapter. Subdirectory Dxctrl: CYLINDER.X Data file for DirectX Control DXCTRL.DLL DirectX Control property page DXCTRL.INF Script file for Microsoft setup program ELSA2.PPM Data file for DirectX Control GLOBE.PPM Data file for DirectX Control RAST1.PPM Data file for DirectX Control SPHERE3.X Data file for DirectX Control Subdirectory Glset: GLSET.DLL GLoria Settings property page GLSET.INF Script file for Microsoft setup program GLSET.TEX Data file for GLoria Settings GLSETENG.HLP English help file for GLoria Settings GLSETDEU.HLP German help file for GLoria Settings GLSETRAY.EXE GLoria Settings Tray utility Subdirectory Monctrl: 24H96.TIM Sample Timing file for ELSA ECOMO 24H96 MONCTDEU.DLL Language extensions for MONCTRL MONCTENG.DLL Language extensions for MONCTRL MONCTRL.CPL Control Panel application for monitor settings Subdirectory Videoctr: VIDEOCTR.EXE Video Control application VIDEOCTR.INF Script file for Microsoft setup program ------------------------------------------------------------------------ 3 Installation NOTE This driver was designed to work properly with Windows NT 4.0 only! When using cdsetup.exe in US-english NT 4.0 with german settings, the installation stops in "display properties". In this case you have to install the drivers manually as described in paragraph 3.3. The tools have been installed correctly. We use the typical installation procedure as described in the Microsoft Windows NT manual install the driver also. There are a some possibilities to install an ELSA display driver: - Text setup during NT installation (3.1) - Running the ELSA Setup utility (3.2) - Change the display driver using the display properties (3.3) NOTE The ELSA display drivers are shipped on CD-ROM and can be installed from there. In cases where there is no CD-ROM it may be necessary to create installation disks first (3.4). 3.1 Text setup during system installation The Windows NT Setup is a text based program that let you install Windows NT. During this setup the Screen shows the text >>Windows NT Workstation Setup Setup has determined that your computer containes the following hardware and software components.<< followed by a list of components. The topic >>No Changes: The above list matches my computer<< is highlighted. Don't press ENTER now! Move the highlight to >>Display: Auto Detect<< and press ENTER. You are now able to select a display from the shown list. NOTE We recommend to select >>Standard VGA (640x480, 16 colors)<< now and continue with paragraph 3.2 later on when Windows NT is installed properly! You cannot install from CD-ROM now. You need to have Installation discs at this time of driver setup. For information about how to create driver installation discs from your CD-ROM read paragraph 3.4. To install an ELSA display driver select >>Other (Requires disk provided by a hardware manufacturer)<<. You will are prompted to insert a manfacturer-supplied hardware support disk into drive A. Insert disk 1, and press ENTER. Select an entry matching your system: >>ELSA i386 640 x 480, 256 colors<< for Intel-based machines, >>ELSA Alpha 640 x 480, 256 colors<< for DEC Alpha machines, >>ELSA PPC 640 x 480, 256 colors<< for PowerPCs. Now accept the list, if it matches your computer. Continue the installation following all instructions. Later on you will be asked to change the ELSA installation disks. During the installation you have to restart your computer. It is now bootet in graphics mode. Later on the property page >>Display properties<< is displayed to enable you to change the default resolution. Don't forget to view the test screen before pressing OK! The Windows NT Setup continues and then reboots the system with the selected resolution. NOTE When you want to use all features supported by the ELSA graphics driver and shipped utilities, it is necessary to install the driver again when Windows NT is running! Refer to paragraph 3.2 or 3.3. 3.2 Running the ELSA Setup utility This Setup utility allows you to install the display driver automatically. To run Setup.exe you can either double click on it in the Microsoft Explorer or choose >>Run...<< in the >>Start<< menue of the taskbar. NOTE: Setup.exe cannot be run from diskettes. You have to copy all your installation disks to a directory on a hard disk drive before or start the program from the ELSA WINNERWare CD. 3.2.1 Additional Configuration Options The Auto Setup utility SETUP.EXE reads the file SETUP.INI in which some options may be set. The section [Setup Options] provides the following keys: - QuietInstall=ON/OFF; ON: SETUP.EXE installs the graphics display driver without need for any user input. (default: OFF) - AutoReboot=ON/OFF; ON: After copying the files the machine is rebooted to complete the installation. (default: OFF) The section [Tools] provides a "InstallableFiles" key. There are listed all additional installation script files that are also installed when choosing "Install ELSA graphics display drivers and utilities". These installation script files have to provide a [DefaultInstall] and [DefaultUninstall] section, so that they can be easily uninstalled/installed using "Add/Remove Programs, Install/Uninstall..." in the control panel. 3.2.2 Options and comments - Before running the Auto Setup utility close all running programs and the >>Display Properties<< window. - The Auto Setup cannot install the driver from diskettes. - On slow CD-ROMs a timeout can cause the Auto Setup to stop installation. In that case copy the driver directory to your harddisk and install from there. - Auto Setup only supports Windows NT 4.0 build 1381 in english and german language. - SETUP.EXE can be called with a parameter. This has to be the path and the name of an .INF file. Example: SETUP.EXE D:\WINNER\3000M\WINNT40\ELSA.INF - When more than one Adapter is supported by the .INF file the first item displayed in the Install list box is installed. 3.3 Change the display driver using the display properties (manual installation) You can install a graphics driver using the Display Properties sheet. Open the Display Property sheet. Select the page >>Settings<<, press the button >>Display Type...<< to open the dialog with the same name and select >>Change...<< in the Adapter Type frame. The >>Change Display<<-Dialog opens. Don't look in the Manufacturers or Display list! NOTE The entry >>Elsa WINNER 1000<< in this listbox will install the general purpose S3 driver designed by Microsoft! The entries in the Manufacturers >>S3<< list can be used but may not allways work properly. Here also a general purpose driver is installed! Click the button >>Have Disk...<< to install the ELSA drivers. Windows NT prompts you to enter the disk with the driver or browse the path. Select >>Browse...<< when installing from CD-ROM and locate the file ELSA.INF for the driver fitting your hardware. When installing from disks, insert the first driver disk. Select the >>OK<<-Button now. A list box appears. There choose the entry matching your graphics adapter and press >>OK<<. Confirm the >>Third-party Drivers<< dialog with >>Yes<<. Now the driver files and utilities are copied and installed to your harddisk. When installing from diskettes the >>Insert Disk<< dialog askes you to change the disks. The >>Installing Driver<< window informes you that the driver has been installed. Confirm this message and close all display settings windows until you are asked to reboot your computer. NOTE With Windows NT 4.0 graphic drivers cannot be loaded dynamically. This is not an ELSA limitation. To activate the ELSA driver, the computer has to be restarted so please press >>Yes<< in the >>System Settings Change<< dialog. When you've selected to restart, the system will reboot and the initial installation is finished. NOTE Windows NT 4.0 will now restart in a resolution of 640*480 pixel at 256 colors and 60Hz refresh. When you have updated your driver the previous resolution is taken. Refer to your Windows NT help on how to change the display properties settings. After Windows NT is restarted the dialog >>Registry Editor<< informs you that some information has been entered to the registry. This was done to install the display property pages. Simultaneously the Display Properties sheet opens with the >>Settings<< page and a dialog >>Invalid Display Settings<< that tells you that a new driver was installed and you have to select your preferred display resolution. The ELSA utilities can be installed by clicking with the right mouse button in the Explorer on the appropriate .INF File and selecting "Install...". NOTE: For Deinstallation, choose "Add/Remove Programs" in Control Panel and select the utility you want to deinstall. 3.4 Installation disks You can create installation disks by copying files from the WINNERware CD-ROM or a downloaded file to diskettes. There is not enough space for all files on one disk so you have take three empty disks labeled "ELSA Windows NT 4.0 DISC 1", "ELSA Windows NT 4.0 DISC 2" and "ELSA Windows NT 4.0 DISC 3". Now copy the following files from your CD-ROM to: - Disk 1 ("ELSA Windows NT 4.0 DISC 1"): DISK1 ELSA.INF ELSA.HLP LIESMICH.TXT README.TXT SETUP.EXE SETUP.INI TXTSETUP.OEM I386\WINNER.SYS I386\WINNER.DLL I386\WINNERMB.DLL - Disk 2 ("ELSA Windows NT 4.0 DISC 2"): DISK2 ELSA.INF TXTSETUP.OEM I386\ELSAOGL.DLL I386\GLSET\GLSET.DLL I386\GLSET\GLSET.INF I386\GLSET\GLSET.TEX I386\GLSET\GLSETDEU.HLP I386\GLSET\GLSETENG.HLP I386\GLSET\GLSETRAY.EXE - Disk 3 ("ELSA Windows NT 4.0 DISC 3"): DISK3 ELSA.INF TXTSETUP.OEM I386\DXCTRL\CYLINDER.X I386\DXCTRL\DXCTRL.DLL I386\DXCTRL\DXCTRL.INF I386\DXCTRL\ELSA2.PPM I386\DXCTRL\GLOBE.PPM I386\DXCTRL\RAST1.PPM I386\DXCTRL\SPHERE3.X I386\MONCTRL\MONCTRL.CPL I386\MONCTRL\MONCTDEU.DLL I386\MONCTRL\WONCTENG.DLL I386\MONCTRL\24H96.TIM I386\VIDEOCTR\VIDEOCTR.EXE I386\VIDEOCTR\VIDEOCTR.INF For Alpha- or PowerPC-Installation disks you have to replace the I386\-folder by the ALPHA\- or PPC\-folder with containing files from your CD-ROM. 3.5 Check whether the installation was done properly There are several posibilities to get the version number of the ELSA Windows NT graphics driver and to determine whether the installation was done properly. 3.5.1 Display Properties Open the Display Properties window as described in your Windows NT manual. Select the >>Settings<< page and click on >>Display Type<<. The dialog >>Display Type<< gives information about the installed adapter, the running display driver and the hardware recognized by the driver. NOTE The driver has to be installed to use this feature! 3.5.2 ELSA Monitor Control Open the Control Panel and select the icon >>MonCtrl<<. When running an ELSA driver the version number of the driver is displayed above the OK and Cancel button. 3.5.3 Checking the driver files Use the Explorer to watch the file properties for either one of the files WINNER.SYS, WINNER.DLL or WINNERMB.DLL. The files can be found in the directory System32\Drivers and System32 of your Windows NT. ------------------------------------------------------------------------ 4 Additional Configuration Options 4.1 How to configure the driver In the following the settings of an ELSA graphics driver for Windows NT and the corresponding entries in the registry database will be explained. Changes can be done with the ELSA utilies MonCtrl, GLoria Settings or manually with the registry editor. NOTE Unexperienced users should not make any changes to the registry directly! Use the utilities! 4.1.1 ELSA Monitor Control Start the ELSA MonCtrl utility doubleclicking the "ELSA MonCtrl" icon found in the Control Panel. Changes in MonCtrl will affect the entries in the registry. 4.1.2 GLoria Settings The ELSA GLoria Settings property page allows you to configure the 3D options on ELSA GLoria graphic adapters. 4.1.3 DirectX Settings On graphic adapters that support Direct Draw the ELSA DirectX settings property page allows you to configure Direct Draw options. Direct 3D is not supported with Windows NT until now. 4.1.4 Video Control The ELSA Video Control utility allows to configure the video output on graphic adapters with Trio64V2-DX oder Virge-DX. 4.1.5 Registry Editor Windows NT stores its configuration information in a database that is organized in a tree type format. The Registry Editor enables you to inspect and modify the Registry. To run Registry Editor, run REGEDT32.EXE (in the SYSTEM32 directory). The entries for the ELSA WINNER graphics driver are placed in the window HKEY_LOCAL_MACHINE in the path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WINNER\. 4.2 Multi Screen Options Some ELSA graphics adapters can be used in a multi screen mode. Two or more adapter cards and just as much monitors are driven from one computer. This will result in an enlarged desktop. A list with graphics adapters that support multi screen is found in 4.2.3. 4.2.1 Installing multi screen There is no special multi screen installation. After you have placed a second ELSA graphics adapter into your computer the Control Panel offers you new extended resolution in the "Display" utility. NOTE There is no special information that multi screen is enabled. You can only see this in the extended resolutions. 4.2.2 Configuration of the multi screen mode The entries "DesktopOnMaximize" and "ReverseScreenOrder" in the registry database influence the multi screen operation. NOTE Look for the frame "Multi Screen Options" in the MonCtrl utility. 4.2.2.1 DesktopOnMaximize This switch adjusts how dialogues and windows are displayed on the N screens. NOTE Look for "Maximize on all screens" in the MonCtrl utility. 0x0: When maximizing a window it be displayed only on the left screen. Dialogues will appear on the left screen. Advantage: Dialogues and windows aren't split by screen borders. Disadvantage: Dialogues always appear left, even if the application runs on the right screen. Position settings of MDI-applications (e.g. Microstation) will be lost after a restart of the program. 0x1: When maximizing a window it fills out all N screens. Advantage: Position settings of MDI-applications (e.g. Microstation) will be restored after a restart. Disadvantage: Dialogues and windows may be displayed on screen borders. 4.2.2.2 ReverseScreenOrder This entry exchanges the order of the N screens. NOTE "Reverse screen order" in the MonCtrl utility. 0x0: The order of the adapters is 1, 2, ..., N 0x1: The order of the adapters is N, ..., 2, 1 4.2.3 Supported graphic adapters Until now only combinations of equal ELSA graphics adapters from the following list are supported: GLORIA 4 GLORIA 8 GLORIA M GLORIA L WINNER 1000 AVI WINNER 2000 Pro/X NOTE You can only use adapters with the same memory equipment. 4.3 Monitor Timings With timing files made for your monitor you may: - Install new resolutions for a better usage of the possibilities supported by your monitor. - Modify new timings for a given resolution. NOTE Look at the frame "Monitor timings for:" in the MonCtrl utility. 4.3.1 Configuring the monitor timings The registry entries belonging to the monitor timings are placed in the subfolder WINNER\DeviceX\. 4.3.1.1 Monitor.Select This entry selects how the timing file shall be used. Ignore: All entries in the timing file will be ignored. Prefere: Resolutions listed in the timing file will be favored. If the driver supports the same resolution as listed in the timing file, the timings of the file will be prefered. Driver resolutions without correspondence in the timing file are not affected and displayed. Exclusive: All standard resolutions of the driver are thrown away. Only the new timings of the timing file are offered in the "Display"-Tool. 4.3.1.2 Monitor.Name In Monitor.Name a string to identify the timing entries is stored. This should be an identifier for ypur monitor, e.g.: ELSA GDM-17E40T 4.3.1.3 Monitor.Timings This entry containes binary data with the monitor timings taken from the timing file. These values are written by the MonCtrl utility. 4.3.2 TIM file format A file with timing entries has the extension ".TIM". It has to be placed in the SYSTEM32 folder of your Windows NT. The files containes lines with ASCII text and can be modified with every editor (e.g. NOTEPAD.EXE). The first line names the timing list (e.g. "ELSA GDM-17E40T"). This is the string displayed in MonCtrl an stored in Monitor.Name. In each of the following lines one timing is defined. Every line containes 14 comma separated values. The meaning of the values is (in correct order): - xRes: Number of pixels in X direction (e.g. 1024). - yRes: Number of lines in Y direction (e.g. 768). - Bpp: Number of bits for each pixel, for colors (e.g. 16). - Hz: Refresh frequency in Hertz (e.g. 79). - PxClk: Pixel clock in kHz (z.B. 95455). - Ht: Horizontal total in pixels (e.g. 1312). - Hfp: Horizontal frontporch in pixels (e.g. 16). - Hsw: Horizontal sync-width in pixels (e.g. 96). - Hbp: Horizontal backporch in pixels (e.g. 176). - Vt: Vertical total in lines (e.g. 800). - Vfp: Vertical frontporch in lines (e.g. 1). - Vsw: Vertical sync-width in lines (e.g. 3). - Vbp: Vertical backporch in lines (e.g. 28). - If: Interlaced flag (should allway be 0). With the given examples the file would look as follows: ELSA GDM-17E40T 1024,768,16,79, 95455, 1312,16,96,176, 800,1,3,28, 0 1024,768,32,... NOTE On the ELSA drivers CD-ROM there is a DOS utility (WINSETUP.EXE) to find out the timings for your monitor. 4.4 Gloria/OpenGL settings The following descriptions are only meant for the ELSA Gloria 4/8 graphic adapters. They belong to the 3D extensions supported by the OpenGL graphics interface. NOTE For all entries there is a correspondence in the GLoria Settings utility in the frame "GLoria Options" 4.4.1 ICD extensions The following parameters of the Installable Client Driver (ICD) affect the behaviour of the 3D functions on the Gloria. 4.4.1.1 ICDInterface.Disable This switch enables or disables the OpenGL support by the ICD driver. NOTE "Disable 3D-Extensions" in GLoria Settings. 0x0: OpenGL will be supported by the Gloria (default). 0x1: Software-OpenGL (no GLint) or OpenGL using 3D-DDI 4.4.1.2 ICDInterface.ExportAlpha Allows the hardware to use the softwares alpha channel. With Programs which don't use the alpha channel this may cause an performance loss up to 25 %. NOTE "Use alpha channels" in GLoria Settings. 0x0: The driver doesn't export an alpha channel (default). 0x1: The driver exports an alpha channel. 4.4.1.3 ICDInterface.NumberOfDisplayBuffers This switch enables and disables DoubleBuffering. The entry stands for the number of buffers. NOTE "OpenGL buffers" in GLoria Settings. 0x1: Only one display buffer is used; no DoubleBuffering. 0x2: DoubleBuffering enabled (default). 4.4.1.4 ICDInterface.SizeOfBuffer This is used to control the size in longs of the shared memory block allocated to each individual rendering context. This buffer is used when DMA is disabled or the entire DMA buffer is in use. After the next restart this change will take effect. NOTE "Interface buffer size" in GLoria Settings. Valid values: 0x100 to 0x10000, the default is 0x10000 (64 kB). 4.4.1.5 ICDInterface.SupportSingleBufferedGDI This flag decides how GDI and OpenGL commands are handled in the same window in the front buffer. NOTE "GDI in single buffered modes" in GLoria Settings. 0x0: GDI commands cannot be drawn in OpenGL windows. 0x1: OpenGL and GDI can simultaneously use the front buffer (default). 4.4.1.6 ICDInterface.SupportDoubleBufferedGDI Lets OpenGL export the ability to let OpenGL and GDI draw in the back buffer. NOTE "GDI in double buffered modes" in GLoria Settings. 0x0: GDI commands cannot be drawn in OpenGL windows (default). 0x1: OpenGL and GDI can simultaneously use the back buffer. (recommended for 3D Studio MAX) NOTE It exports the flag but all GDI calls are drawn in the front buffer! 4.4.1.7 ICDInterface.SupportOverlayPlanes This switch enables the driver to support overlay planes, which are e.g. used by Softimage. NOTE "Support Overlay Planes" in GLoria Settings. 0x0: No support for overlay planes (default). 0x1: Overlay planes are supported. 4.4.1.8 ICDInterface.VBlankWait This switch enables the driver to turn on the wait for vertical blanks when swapping OpenGL buffers. NOTE >>Wait on Vertical Blank<< in GLoria Settings. 0x0: Swap buffers is not syncronized with vertical blank (default). 0x1: The driver waits for vertical blanks. 4.4.1.9 ICDInterface.PageFlipping In True Color the driver provides a page flipping mode when swapping OpenGL buffers instead of blitting. 0x0: Don't use page flipping anyway. 0x1: Driver uses page flipping instead of blits when possible (default). 4.4.2 GLint-DMA settings The parameters of the GLintDMA group configure the DMA capabilities of the GLint. 4.4.2.1 GLintDMA.NumberOfBuffers This is used to determine the number of individual DMA buffers that can be in use at any one time. After the next restart this change will take effect. NOTE "DMA buffers" in GLoria Settings. Valid values: 0x0 to 0x4, the default is 0x4. 4.4.2.2 GLintDMA.NumberOfSubBuffers Used to control the ICD drivers subdivision of the DMA buffer. NOTE "DMA subbuffers" in GLoria Settings. Valid values: 0x0 to 0x9, the default is 0x5. 4.4.2.3 GLintDMA.SizeOfBuffer This is the total size of the DMA buffer which is devided up amongst the individual processes that use DMA. After the next restart this change will take effect. NOTE "DMA buffer size" in GLoria Settings. Valid values: 0x100 to 0x10000, the default is 0x8000 (32 kB). 4.4.2.4 GLintDMA.CachedBuffers This switch enables the driver to cache GLint data in the processors cache. Though the GLint reads all date from the main memory, differences between memory and cache may appear. After the next restart this change will take effect. NOTE "Cached DMA" in GLoria Settings. 0x0: forces uncached DMA 0x1: forces cached DMA 0x2: let the driver decide whether it uses cached or non cached DMA (default). 4.4.3 OpenGL.UseFastClear This value affects the usage of fast clear planes. When running multi-threaded applications it may be necessary to disable the useen of the fast clear planes. After the next restart this change will take effect. NOTE "Use Fast Clear Pages" in GLoria Settings. 0x0: Fast clear planes disabled. 0x1: Fast clear planes enabled NOTE For MicroStation this switch has to be set! 4.4.4 OpenGL.UseHiQualityTexture This switch affects the precision and resolution for texture mapping. 0x0: Normal precision and resolution 0x1: High precision and resolution 4.4.5 OpenGL.SupportSoftimage This switch fixes corrupted menue and window borders in Softimage 3.01. Use this switch only when running Softimage 3.01! NOTE "Support Softimage" in GLoria Settings. 0x0: Softimage fix not activated (default) 0x1: Softimage fix is active. 4.4.6 OpenGL.SupportSoftimage351 This switch enables functions especially to support Softimage 3.51. Use this switch only when running Softimage 3.51! NOTE "Support Softimage 3.51" in GLoria Settings. 0x0: Softimage 3.51 fix not activated (default) 0x1: Softimage 3.51 fix is active. 4.4.7 OpenGL.DisableMipMaps This switch allows the user to force rendering performance when using textures by disabling the mipmaping. This overrules every applications OpenGL command for texture filtering. At the same time you will lose accuracy. NOTE Slider "Texture Quality" in GLoria Settings. 0x0: Mip-Maping is enabled 0x1: Mip-Maping is disabled 4.4.8 OpenGL.TextureCompression This value is used to reduce the texture size actually downloaded to the texture memory on the graphics board by simply shrinking the texture. This will enhance the rendering performance. At the same time you will lose accuracy. NOTE Slider "Texture Quality" in GLoria Settings. 0x0: No texture compression 0x1: Texture compression by 1/4 0x2: Texture compression by 1/16 0x3: Texture compression by 1/64 4.5 Additional Options 4.5.1 EnableDeviceBitmaps This value is used to turn on and off the usage of device bitmaps. When enabled the driver supports more performance. 0x0: Device Bitmaps disabled 0x1: Device Bitmaps enabled (default) 4.6 ELSA POWERlib ELSA offers optional for the programmer the toolkit POWERlib for creating your own applications using the ELSA graphics board for graphical output. This tool is available for Windows NT. ------------------------------------------------------------------------ 5 Known Problems - If the application under OpenGL requests "Double Buffering" and the GLoria cannot realize it anymore (1024x768x32 bpp), software emulation will be automatically installed. To force hardware OpenGL you have to disable double buffering in your application! - The driver cannot run on a system where a COM4 port is installed. - Don't use the standard S3 display driver. While setup detects your computers hardware choose cancel to avoid the installation of the S3 driver. - No mouse cursor: You have installed the S3 driver shipped with Windows NT. - When running an OpenGL application and switching from DOS box to DOS fullscreen and back, the OpenGL-Application crashes. The same happens changing the Display Properties. In that cases the driver is initialized by Windows NT loosing all information about running OpenGL tasks. - Installing the driver in from diskettes as described in the >>Text Setup<< paragraph doesn't acivate all 3D and Direct Draw settings. You have to install the driver for new after the Windows NT setup is finished. - When the ELSA graphics board is not recognized try another PCI slot. Some board manufacuters have implemented PCI slots that are not PCI compliant. ------------------------------------------------------------------------
