------------------------------------------------------------------------

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.
