2) Click Setup.
3) Follow the on screen prompts.
4) After installation you may need to reboot the system.



Troubleshooting Voodoo Graphics
-------------------------------

Q: I have an S3 968/868 video card, why does my system lock
up when I run a Glide or Direct3D title.

A: S3 968 and 868 chipsets may misreport the mapped memory used.
There is a chance that your Voodoo Graphics card will be 
assigned by Plug and Play a memory range that is used by the S3
card, but not reported.   The Voodoo Graphics card can be 
relocated by:


	Windows 95 Users:  Please download the S3 Fix kit
	from the Downloads/Updates section of http://www.3dfx.com


	Windows NT Users: An NT service called NTREMAP is 
        installed when Glide is added to an NT system.
	NTREMAP can change the memory address of a Voodoo 
	Graphics board and prevent a conflict with an S3 card.

	To use NTREMAP, add the following registry values to:
	\HKLM\Software\3Dfx Interactive\NTRemap
	
	Value Name	Type	Value
	----------      ----    -----
	EnableNTRemap	DWORD	1 (HEX) 
	ForceAddress	DWORD	12000000 (HEX)

	The Force Address setting will vary, in this example
	0x12000000 is used.  This is normally free on most
	systems.

	NOTE: If you use an address that over-writes another
	device, Windows NT may not boot.  If such a problem 
	occurs, power off the system and remove your Voodoo 
	Graphics.  Alter the registry to use a different
	memory range (or remove the ForceAddress setting).
	Then Reinstall the Voodoo Graphics card into your 
	system.

Q: The display seems dark when a Glide title is running, how
do I make the display brighter?

A: Using a file editor (ie: Notepad), edit your \AUTOEXEC.BAT
file.  Add the following lines

	SET SST_RGAMMA=1.7
	SET SST_BGAMMA=1.7
	SET SST_GGAMMA=1.7

	1.7 is the default value, increasing past this setting
	will raise gamma.  It is however suggested that you
	don't raise the setting past 1.9

Troubleshooting Voodoo Rush
-------------------------------

####

Q: The display seems dark when a Windows based Glide title is
running, how do I make the display brighter?

A: Adjust the Video Chroma setting by clicking on the taskbar
icon.  This will brighten Windows based Glide titles.  It will
not adjust DOS based Glide titles.
