- 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:

-
- 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.
-

-
- 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 "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.
