The following document provides an overview of the Righteous 3D.



HARDWARE OVERVIEW

The Voodoo Graphics based 3D Accelerator is a PCI 3D Accelerator. 
Voodoo Graphics 3D accelerators only provide 3D functionality and
cannot be used as a primary display adapter. An existing graphics 
card or motherboard graphics chip is required. Simply insert the
card into an available PCI slot. Connect the pass-thru cable between
the Righteous 3D and your other 2D card: the monitor connects 
directly to Righteous 3D. In this manner the Voodoo card by default 
passes the video signal from the 2D card to the monitor. When 3D
acceleration is required, Righteous clicks into operation and begins 
processing video data. The switch to 3D rendering is controlled from 
either Glide or the Direct3D drivers and is transparent to the user. 

The Righteous 3D card possesses the following:

	Processing Chip:  3Dfx Interactive Voodoo Graphics chip
	On Board Memory:  4MB EDO: 2MB for Texture Mapping and
			  	   2MB for Polygon Mapping. 

The following processors and architectures are supported:

	*  Intel Pentium		
	*  Intel PentiumPro
	*  Intel Pentium II
	*  Intel 486 (not supported by many titles)
	*  Cyrix 6x86
	*  Cyrix 5x86
	*  AMD K5
	*  AMD K6
	
The Righteous 3D does work in conjuction with AGP video cards.
 


SOFTWARE OVERVIEW

The Righteous 3D supports the x86 platform. 

	* Windows 95 or higher (Direct3D and Glide)
	* DOS 5.0 OR HIGHER (Glide)
	* Windows NT 3.51 or higher (Glide on x86 systems only).
		Windows NT does not currently support the Righteous 3D at 
		the hardware level: only at the software level. 
	*  As a minimum, DirectX 2.0 or greater must be installed to use 
		Direct3D.
	*  The Righteous 3D supports DirectX 5.0, which can be downloaded 
		from www.orchid.com.
					
It bears mentioning that DirectX and Glide are composed of a suite of
multimedia system components and device drivers. As such, the various 
components possess differing versions. An upgrade in one component
does not mean that all components are upgraded. Bear this is mind when
new driver versions appear.



GLIDE

Glide is 3Dfx's native API and is supported by 3Dfx Interactive, Inc. 
(see www.3dfx.com for more information.) 

Glide titles will not run without a 3DFX based accelerator card, such
as Righteous 3D.

Other API's are supported by using Glide as a layer. These APIs
include Renderware, Brender, GLQuake Driver (3Dfx's GLQuake Driver). 
And don't be affraid of trying increased refresh rates. Many customer's
experience great results even at 120hz (check you monitor's documentation
prior to setting higher refresh rates).



DIRECT3D

Direct3D (a Microsoft supported API) is implemented as a secondary
device driver. (see www.microsoft.com/mediadev for more information).

Microsoft's Direct3D API can refer to two modes of 3D display:
	
	1) Retained Mode (refers to 3D in a window). 
	2) Immediate Mode (refers to full-screen 3D). 

The Righteous 3D only accelerates the Immediate Mode of	Direct 3D.



SUPPORTED SCREEN RESOLUTIONS

Righteous 3D supports the following resolutions.
	
	* 512x384 resolution (72, 75, 85 and 120 hz)
	* 640x400 resolution (70, 75, 85 and 120 hz)
	* 640x480 resolution (60, 75, 85 and 120 hz) 
	* 800x600 resolution (60, 75, 85 and 120 hz) w/o z-buffer

Note:  Individual applications may or may not use z-buffering. If an 
application uses a z-buffer it will be unable to run on Righteous 3D at 
800 x 600. Check your application's documention to determine whether it
uses a z-buffer.

Higher resolutions in Direct3D (such as 1024 x 768) are possible, but
come at a cost--they will not be accelerated by Righteous 3D. Without
acceleration, texture data gets reduced and pixelated. Another side 
effect is reduced frame rate.



RUNNING RIGHTEOUS 3D UNDER WINDOWS NT:

Windows NT does not support Direct3D at the hardware level:
only at the software level, as of version 4.0 (service pack 3).
Direct3D applications will run under NT, but true 3D graphic
acceleration will not occur.

Running Glide on Windows NT requires Windows NT Workstation 3.51 or 
higher. Windows NT Workstation 4.0 is required to run any 3Dfx Demos
as DirectInput and DirectSound. 3Dfx Runtime drivers may be obtained 
from 3Dfx Interactive Inc. at www.3dfx.com. 

Although hardware accelerated Direct3D is not currently available for 
Windows NT, it's expected to be available for Windows NT 5.0. 3Dfx is 
committed to providing Direct3D drivers once hardware accelerated 
Direct3D support is available in Windows NT.

 

TROUBLESHOOTING

1)  Try placing your 2D video card in PCI slots 1 or 2. Place the 
	Righteous 3D card in either PCI slots 3 or 4. You might also 
	consider leaving one or more open slots between them, if possible.

2)  It is always a good idea to double check video card insertions into 
	the motherboard, and note that all cables are properly in place. 
	It's also possible that your monitor cable is not the correct
	type for the Righteous 3D. See Appendix A in your owner's 
	manual for the proper pin-out information to determine whether
	your cable is correct. 

3)	For those loading a game card for the first time, the proper 
	installation of Righteous 3D involves two important steps prior 
	to loading any games: 1) loading the drivers, and 2) loading DirectX. 

	For those experienced gamers who have Glide, Direct3D and DirectX 
	already loaded, the installation of the Righteous 3D drivers should 
	be enough for successfull 3D acceleration. 

	It's important to note that DirectX should not be uninstalled from 
	any operating system. Also note that one cannot reinstall earlier 
	versions of DirectX over later versions.  	

4)	After loading the Righteous 3D drivers, you can determine whether 
	they are correctly loaded by following this procedure. From the 
	Desktop, click START--FIND--FILES AND FOLDERS, and key-in the 
	following at the prompt: 

			c:\windows\inf\r3dsetup.inf  <enter>

	If Window's locates r3dsetup.inf the in c:\windows\inf 
	subdirectory, you have successfully loaded the drivers
	(Go to step 5 if r3dsetup.inf was not found.)

5)	To load the Righteous 3D drivers while in Windows 95, let's
	start from the Desktop. Proceed to CONTROL PANEL--ADD NEW 
	HARDWARE--NEXT--NO (Don't let Windows search for new hardware)--
	NEXT--(toggle down to SOUND, VIDEO AND GAME CONTROLLERS)--
	(click the HAVE DISK option)--(place your Righteous 3D
	cd into your cd-rom).
	
	Windows should find your Righteous 3D hardware at this point.
	Click OK to begin loading the drivers. 

6)  When trying a 3D game, and you experience system lock-ups 
	or blank screens, try the following.  Go into CONTROL PANEL-- 
	SYSTEM--DEVICE MANAGER--SOUND, VIDEO AND GAME CONTROLLERS-- 
	RIGHTEOUS 3D--PROPERTIES--RESOURCES. Uncheck the box 
	"Use Automatic Settings", then adjust memory settings from the
	"F-range" to the "D-range." Make sure that such a move does not
	raise a conflict with another device. Reboot your system and retry 
	the game. 

7)  If your primary video card has 3D capabilities and your not certain
	which card is providing 3D support, note the following: When the 
	Righteous 3D is invoked it emits one or more audible clicks. 

8)  If you discover in DEVICE MANAGER that SOUND, VIDEO AND GAME CONTROLLERS 
	does not contain an entry for the Righteous 3D. Check to see if a 
	device called PCI MULTIMEDIA VIDEO DEVICE is listed under 
	OTHER DEVICES. If so, try removing it and restart your system. 

9)  If a game is coming up with a distorted display or with random geometric
	shapes, try adjusting your refresh rates to a lower level. Most
	2D video cards come with applications that allow these adjustments:
	and so does Righteous. Note the Righteous 3D tab in CONTROL PANEL--
	DISPLAY. The settings for refresh rate between your 2D and Righteous
	should be the same. Check your monitor's documentation to ensure
	that it can handle the changes.

	It's also a good idea to set your resolution to 640 x 480 and colors
	to 16-bit (65K colors) if the above problems occur.

10) If your standard video card contains the old S3 video chip (prior to
	S3 Virge) and your experiencing video freeze, random shapes or 
	random colors, try the following changes. In CONTROL PANEL--
	ADD/REMOVE PROGRAMS, remove an item called "S3 Refresh" from your 
	system. Reboot and try a game. If problems persist, remove your 
	current video drivers (as supplied from manufacturer) and reload 
	using Windows 95 supplied drivers. (CONTROL PANEL--DISPLAY--SETTINGS--
	ADVANCED PROPERTIES (or CHANGE ADAPTER TYPE)--CHANGE--SHOW ALL DEVICES.)
