1	Introduction

	This file explains how to install and configure an ELSA graphics
	driver for Windows NT.

1.1	Requirements
	This software runs on every ELSA PCI-Bus graphics card.

1.2 	List of files

	The directory with the ELSA graphics driver for Windows NT
	contains the following files:

	TXTSETUP.OEM	Script file for setup at boot time
	OEMSETUP.INF	Script file for Microsoft SETUP.EXE
	WINNER.SYS	ELSA Miniport driver
	WINNER.DLL	ELSA Display driver
	WINNERMB.DLL	ELSA Multi-Display driver
	WINCTRL.CPL	Display control application
	WINCTRLD.WRI	German manual for WinCtrl
	WINCTRLE.WRI	English manual for WinCtrl
	WINCTDEU.DLL	Language extensions for WINCTRL
	WINCTENG.DLL	Language extensions for WINCTRL
	README.TXT	The file you are reading
	LIESMICH.TXT	German version of the file README.TXT
	DISK1		Identifier for the first disk
	DISK2		Identifier for the second disk
	ELSAOGL.DLL	ELSA OpenGL driver


1.3 	How to determine the driver's version number

	There are a few posibilities to get the version number for an
	ELSA NT graphics driver.

1.3.1 	Using the Control Panel

	Start the control panel (CONTROL.EXE) and select the icon
	"Display". There, click the button "Change Display Type". In the
	following dialog the version number is displayed in the box
	driver information.

	NOTE	The driver has to be installed to use this feature!

	NOTE	Due to a non-ELSA problem the version number is only
		displayed in an US-english installation if Windows NT.

1.3.2 	Using WinCtrl

	Choose the Icon "ELSA WinCtrl" in the control panel. Above the
	exit-buttons the  version number is displayed.

	NOTE	The driver has to be installed to use this feature!

1.3.3 	Using the File Manager

	Use the File Manager 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.

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

2	Installation

	NOTE    To install the ELSA drivers, use the typical installation
		procedure as described in the Microsoft Windows NT
		manual.

2.1 	Installation during system installation

	During the first or a new customized installation of Windows NT
	you will be asked to accept the hard- and software components.
	In this text screen titled "Windows NT Workstation Setup" setup
	tries to determine your computers hard- and software.  Here
	don't accept "The above list matches my computer" and select the
	line after the text "Display:".  In the following screen select
	"Other (Requires disk provided by a hardware manufacturer)".
	You will be sked to insert a disk into drive A:.  Insert disk 1,
	press ENTER and select one of the provided resolutions.  Accept
	the list, if matches your computer.  Continue the installation
	following all instructions.  Later you will be asked to change
	the diskettes.

	During the installation you have to restart your computer.  It
	is now bootet in graphics mode.  Later on the dialog "Display
	settings" enables you to change the default resolution. Read
	chapter 3.

	NOTE	If you select Express setup you´re not able to change
		the display driver.  In this case read chapter 2.2.

	NOTE	You cannot install from CD. You have to create
		installation disks (2.3).

2.2 	Later installation

	Open the "Control panel" window in the "Main" program group
	and select "Display" to start the "Display Control Application".
	Click on "Change Display Type..." and select "Change..." in the
	upcoming "Display Type" dialog. A "Select Device" dialog appears
	where you can see the already available device drivers
	(Listbox: "Models").

	NOTE    The entry "ELSA Winner 1000" in this listbox will
		install the general purpose S3 driver designed by
		Microsoft and NOT the ELSA drivers!

	NOTE	The installation from CD ROM is not possible.
		Please copy all files from the subdirectory
		\WINNT35 on a disk or your harddisk.

	Choose "Other..." to install the ELSA drivers. Windows NT
	prompts you to enter a path where it can find the drivers.
	Change the default "A:\" to the path where to find the
	driver files e.g. "D:\WINNER\2000PROX\WINNT35\I386" or to the
	corresponding directory and confirm with "OK".
	The "Select Device" dialog's "Models" listbox is now extended
	by an ELSA specific entry: "ELSA WINNER Vxxx". Highlight this
	entry and click on "Install".

	IMPORTANT       A simple "OK" at this point will discard
			your selection.

	Please confirm the "Installing Driver" box and select "New"
	in the "Windows NT Setup" dialog to ensure that the new drivers
	will be loaded. Continue if the path for the WINNER display driver
	files is correct. Now the driver is installed. Afer that the
	"Installing Driver" box should appear and inform you that the
	drivers were installed successfully. Confirm the following
	dialog.

	NOTE    With Windows NT 3.51 graphic drivers cannot be loaded
		dynamically. This is not an ELSA limitation.

	To activate the ELSA driver, please press "Restart Now",
	otherwise select "Don't Restart Now".
	When you've selected "Restart Now", the system will reboot and
	the initial installation is finished.

	NOTE    Windows NT 3.51 will now restart in a resolution of
		640*480 pixel at 256 colors and 60Hz refresh. To change
		this resolution use the "Display" application (refer
	   	also the following chapter "3. Changing the resolution
	 	after installation").

	NOTE	The OpenGL driver is automatically installed with the
		Windows NT 3.51 driver.

2.3 	Installation from diskettes

	If you don't have any installation disks, you can create these
	using your CD-ROM or a downloaded file. There is not enough
	space for all files on one disk you have to create two disks.
	Name the first disk "ELSA Windows NT 3.51 DISPLAY DRIVER DISK 1"
	and copy the following files onto it:
		DISK1
		TXTSETUP.OEM
		OEMSETUP.INF
		WINNER.SYS
		WINNER.DLL
		WINNERMB.DLL
	Name the other disk "ELSA Windows NT 3.51 DISPLAY DRIVER DISK 2"
	and copy the following files onto it:
		DISK2
		ELSAOGL.DLL
		WINCTRL.CPL
		WINCTDEU.DLL
		WINCTENG.DLL
		LIESMICH.TXT
		README.TXT

2.4 	Installation from CD-ROM or harddisk
	If you wish to install the driver from CD-ROM or a harddisk,
	all files have to be located in one common directory. The path
	has to be inserted when asked for the location of the driver
	during installation.

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

3	Changing the resolution after installation

	Start the "Display" dialog, it's "Display Settings" gives you
	the chance to adjust 4 parameters.

	- The "Color Palette" contents selections from "256 Colors" to
	  "True Color" depending on the "Desktop Area".
	- The "Desktop Area" depends on the "Refresh Frequency" and
	  the "Color Palette".
	- The "Refresh Frequency" allows you to select various refresh
	  rates.
	- The "Font Size" lets you select large or small fonts.

	NOTE	The "Font Size" selection appears only when you
		have installed Windows NT with "american" language
		settings.

	After selecting a new graphic mode you can check this mode for 5
	seconds.  If the test screen is OK, then select "YES".  Otherwise
	select "No" and make another selection.  Now the well known
	"Display Settings Change" box reappears where you have the
	choice to "Restart" the system or not.

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

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 WinCtrl utility
	or manually with the registry editor.

	NOTE	Inexperienced users should not make any changes in the
		registry directly!  Use the WinCtrl utility!

4.1.1 	Registry Editor

	Windows NT stores its configuration information in a database
	that is organized in a tree type format.  Registry Editor
	enables you to inspect and modify the Registry.  To run Registry
	Editor, run REGEDT32.EXE (in the SYSTEM32 directory).  You can
	also use the menu "Tools"/"Registry Editor" in the application
	"Windows NT Diagnostics" found in the "Administrative Tools"-
	program group.  To edit a value, simply double-click on it to
	invoke an edit dialog.

	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\.

4.1.2 	WinCtrl utility

	Start the ELSA WinCtrl utility doubleclicking the "ELSA WinCtrl"
	icon found in the Control Panel. Changes in WinCtrl will affect
	the entries in the registry.  A manual for the WinCtrl utility
	can be found in the file WINCTRLE.WRI.

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
		WinCtrl 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 WinCtrl
		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 WinCtrl utility.

	0x0: 	The order of the adapters is 1, 2, ..., N (default)

	0x1:	The order of the adapters is N, ..., 2, 1

4.2.2.3 VerticalScreenOrder

	With this switch you can force the screens to be arranged
	vertically instead of horizontally.

	NOTE	"Vertical screen order" in the WinCtrl utility.

	0: Screens are arranged horizontally (default)

	1: Screens are arranged vertically


4.2.3 	Supported graphic adapters

	Until now only combinations of equal ELSA graphics adapters
	from the following list are supported:

	GLoria-L/MX

	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 WinCtrl
		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 WinCtrl
	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 WinCtrl 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 WinCtrl
		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 WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	0x0:	GDI commands cannot be drawn in OpenGL windows
		(default).

	0x1:	OpenGL and GDI can simultaneously use the back buffer.

	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 WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	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	"Disable Fast Clear Pages" in WinCtrl.

	0x0: 	Fast clear planes are used (default)

	0x1:	Fast clear planes are disabled

	NOTE	For MicroStation this switch has to be set!

4.4.4 	OpenGL.UseHiQualityTexture

	This switch affects the precision and resolution for
	texture mapping.

	NOTE	"High Quality Textures" in WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	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 WinCtrl.

	0x0:	No texture compression

	0x1:	Texture compression by 1/4

	0x2:	Texture compression by 1/16

	0x3:	Texture compression by 1/64

4.5 	DCI

	The driver supports primary surfaces.  In Windows NT 4.0 this
	support will be dropped.

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.
