Introduction
============
This Readme describes the above driver for the 3Dlabs Oxygen
VX1-1600SW board.

Once the driver has been installed the display driver release
number can be determined by starting the Display Applet Control
Panel in Control Panels directory. Select the "Display" tab, then
the "Advanced" button, then the "3Dlabs" tab followed by the
"Advanced" button. The Display Driver and OpenGL version numbers
can be found in the "Infomation" tab. The last four digits
following the "-" uniquely identify your driver build.


Prerequisites
=============
• Windows 98 or Windows ME
• Intel Pentium II processor or later


Driver Download Instructions
============================
1. Goto the 3Dlabs web site (at www.3dlabs.com) and locate the driver
   download page.

2. Download the appropriate driver zip file for your board into
   a suitable scratch directory (e.g. C:\3Dlabs).

3. If you have WinZip or a similar program to extract zip files,
   then extract them into the scratch directory (making sure you
   preserve the directory structure inside the zip file.
   If you are using the command line program pkunzip, then open a
   dos prompt window and change directory to your scratch directory:
   > c:
   > cd \3Dlabs
   then unzip the files:
   > pkUnzip -d xxxxxxxx.ZIP

4. Install the new driver by following the install instructions
   below.

5. You can now delete the download scratch directory and its
   contents.


English Install
===============

DO NOT USE THESE INSTRUCTIONS IF YOU ARE RUNNING A NON-ENGLISH 
VERSION OF WINDOWS 98 - SEE THE SECTION BELOW, OTHERWISE PLEASE
FOLLOW THESE INSTRUCTIONS CAREFULLY;

1. If you do not have a 3Dlabs CD or floppy disk set, then please
   follow the download instructions in the previous section 
   to get a Windows 98 driver for your board before plugging 
   it into your machine.

2. Plug in your graphics card and boot the system. When you first
   boot the system after plugging in the graphics card, Windows
   will automatically detect the new hardware and it will start up
   the 'Add New Hardware Wizard'. Select 'CANCEL' since 3Dlabs 
   provide an automated install.

3. If you have a 3Dlabs CD, then insert it into the CD drive - the
   installer menu will normally launch automatically.
   If you do not have autorun enabled on your CD then double click
   on the CD icon on your desktop to launch the 3Dlabs installer
   menu.

   If you downloaded the driver, then navigate to the folder that
   contains the unzipped driver and run setup.exe.

4. Follow the instructions on the screen. Note you must install
   the DirectX7 runtime when this option is offered if you have
   not already installed DirectX7 or later on your computer. If
   you do not then DirectX applications will not run.

5. Choose to reboot the computer when asked at the end of the process.

6. Upon reboot you should be running with full acceleration.


Non-English Install
===================
If you have a non-English language version of Windows 98 then
follow these instructions.

1. If you do not have a 3Dlabs CD or floppy disk set, then please
   follow the download instructions above to get a Windows 98 driver
   for your board before plugging it into your machine.

2. Plug in your graphics card and boot the system. When you first
   boot the system after plugging in the graphics card, Windows
   will automatically detect the new hardware and it will start up
   the 'Add New Hardware Wizard'.

3. If you do not have a driver available to install at this
   point, select 'Cancel' and upon the next reboot of Windows
   the Wizard will automatically start again.

4. Select Next. Ensure 'Search for best driver for your device'
   is selected. Select Next again.

5. If you have a 3Dlabs CD, then ensure the 'Specify a location'
   check box is checked and type in 'X:\Win98' where X is the
   letter of your CD drive. If you downloaded the driver, then 
   ensure the 'Specify a location' check box is checked and type 
   in the location of the scratch directory where you unzipped 
   the files. If you have a set of floppy disks with the drivers 
   on, ensure the 'Floppy disk drives' check box is checked.

6. Select Next.

7. The wizard should now find the driver for the board. Select
   Next twice more and the Wizard will copy the files. Then select
   finish and restart your computer as prompted.

8. Upon reboot you should be running with full acceleration.


Changing display drivers for non-English versions of Windows 98/ME
==================================================================
If you have previously installed a display driver, or you have
installed a Standard VGA driver as the driver for the board,
then follow these instructions to change the driver to the latest
driver. If you selected cancel from the 'Add New Hardware Wizard'
above when booting the system, then you should just reboot your
system rather than following these instructions.

1. Start up the Display Control Panel. Select the Settings tab,
   then the Advanced button and then the Adapter tab.

2. Select Change. You are now in the 'Update device driver Wizard'
   which is very similar to the 'Add New Hardware Wizard', and you
   can proceed from step 4 of the installation instructions above.


IMPORTANT : AUTOMATED INSTALL FAILURE
=====================================
Under some rare circumstances (E.g a previous corrupted graphics 
driver installation or where this driver is replacing a newer one)
the automated install may fail to install the driver correctly. 

If this happens you will probably see one or more dialog windows 
belonging to the Windows Display control panel or the Hardware 
Wizard REMAINING on the screen AFTER you have clicked on the <Next> 
button that appears on the installer "Driver Information" Dialog 
Window which states "DRIVER SETUP IS COMPLETE".  

Under normal conditions, the next step is to install the DirectX 7.0 
drivers. However, in this case, you will need to manually complete
the 3Dlabs Graphics driver installation beforehand, by downloading
the non-English version of the driver install and following the
instructions under "Non-English Install" above.

Note that non-English refers to the installation procedure - the
driver itself is identical to that installed by the "English Install".


Uninstall
=========
The Control panel extension and the application support tool can
be uninstalled by following this procedure:

1. Open the Add/Remove Programs icon in the Control Panel.

2. Highlight the "3Dlabs display driver" in the list and click
   "Add/Remove".

3. Follow the instructions to complete the removal of the
   control panel and application support tool.


Resolutions and Refresh Rates
=============================
The resolutions supported (and maximum refresh rate) for the
Windows Desktop are dependent on your graphics card. For the
VX1/1600SW when driving the SGI flat panel, only 1600x1024
resolution is supported and only the following color depths
are supported:
	High Color (16 bits per pixel)
	True Color (32 bits per pixel)

256 color modes and additional resolutions are supported on
analog monitors, when using the standard VGA connector.

Many refresh rates are supported for all of these modes. The
refresh rate available is typically limited by your monitor type.
The monitor type will be auto detected by Windows if your monitor
supports DDC. If windows does not recognise the monitor, you will
be prompted to install the monitor information disk from your
monitor manufacturer. If your monitor does not support DDC, then
you will have to select a monitor type manually from the display
control panel.

A combination of the DDC information and the monitor type is used
by Windows to determine which modes are available at which refresh
rates.

NOTE: If you have an unknown monitor type, the driver will set the
refresh rate for all modes to 60Hz - which may flicker noticably
on your monitor.


3Dlabs Display Control Panel Tab
================================
The 3Dlabs tab in the Display Control Panel allows control over
the configuration of the 3Dlabs drivers. The control panel is
split into a number of pages. The pages are selected by clicking
on the "Advanced" button on the main page to bring up the
"3Dlabs Display Settings" Panel, and then selecting one of the
tabs on the the top right of the window.

The control panel supports lists of driver settings. The 
"Direct3D support" and "OpenGL support" tabs enable you
to create your own named settings which you can add to the 
list to appear each time the control panel or taskbar tool
(see below) is accessed. 

To obtain help on the various options supported by the control
panel tabs first click on the "?" in the title bar and then click
on the item you want more information on. A help note will
appear near the cursor. Click again to close the window.


Task Bar Utility (only available under Windows 98/ME)
==================================================
This driver release includes a task bar utility which
provides quick access to some of the facilities on the
control panel. To access the application right click on the
3Dlabs icon in the taskbar. This tool provides ;-

* Quick and convenient display resolution changing
* Access to the 3Dlabs web site
* Shortcut access to the display control panel 
* Instant selection from a list of application settings
* Quick display of the driver settings
* Help on the driver settings

Full documentation is provided through the "Help" item on 
the tool's pop-up menu.


Supported Languages
===================
The Control Panel Tab and the Application Support tool
currently support the following languages:-
Chinese (Simplified)
Chinese (Traditional)
Dutch
English
French
German
Italian
Japanese
Korean
Spanish (modern)


General DirectX advice
======================
This driver requires DirectX7 to be installed, otherwise
DirectX applications will not run.

Some games ( e.g. Unreal ) give you the option to install
DirectX binaries during the game installation. The game
may attempt to force-install older versions of DX binaries
over your current DX binaries. This will almost certainly
lead to the game failing to start up.

You can determine your DirectX version by running the
display control panel and clicking on the 3Dlabs tab and
then the Advanced tab. The DX version is in the DirectX
Information pane in the form:

		DirectX Release:	4.XX.YY.ZZZZ

where XX is the number you require. For example you may see

		DirectX Release:	4.07.00.0700

and so you have DirectX 7 installed.

Now, when a game installer runs you can decline the offer 
to install the old DX binaries.


3D Studio Max 2.x/3.x
=====================
This driver should be used with OpenGL acceleration under 3D
Studio Max 2.x.

Start 3D Studio Max and go to the Preferences dialog box. This
is located under "File\Preferences" in 3D Studio MAX 2.x and
under "Customize\Preferences" in 3D Studio MAX 3.x. Click the
"Viewports" tab and the select "Choose Driver". Ensure that
the "OpenGL" option is selected. Shutdown 3DStudio Max. Before
restarting, delete the 3DStudio Max OpenGL configuration file
that stores information about your OpenGL driver. Doing this
will cause 3DStudio Max to reset some of its options to get
best performance from these drivers. The file is called
oglgfx.ini and is located in your /3dsmax/ directory (or
wherever you installed 3D Studio Max). If the file does not
exist then simply restart 3D Studio Max.

When running through OpenGL, 3D Studio Max defaults to not
backface culling wireframe objects. This may result in
less than optimal performance when manipulating wireframe
objects. This behaviour can be changed from within the
application. Go to the "File/Preferences" dialog box. Click
on the "Viewports" tab and then select "Configure Driver".
Enable the option "Display Wireframe Objects Using Triangle
Strips". This causes wireframe objects to be backfaced
culled and can significantly improve performance. The setting
also causes shared edges within polygons to be drawn which may
not appear as desired.


TrueSpace 4.x
=============
This driver should be used with D3D rendering acceleration for
TrueSpace, as the performance is better than with the OpenGL
renderer.


Incorrect colors in certain games
=================================
Some games show incorrect colors at 16bpp when run under the
initial driver installation settings. To run the following games
you should first select "Games Default" from the list on the
DirectX Support tab of the 3Dlabs control panel, or using the
task bar application if you have this enabled.

Everquest
Nascar3
Shogun Total War
NFS Porche 2000
Alien vs Predator
Final Fantasy VII


Unreal
======
3Dlabs recommend that you use Direct3D to play Unreal.
Patches of the game more recent than version2.22 have introduced
rendering problems on 3Dlabs hardware.
To access the Advanced options menu use the game's safe mode.


Descent3 and OpenGL
===================
3Dlabs recommend that you use Direct3D to play Descent3. Using
OpenGL the game only renders correctly at 640x480 resolution.


Half-Life
=========
You will need to download the patch for at least version 1.0.0.8
from www.sierra.com to use hardware accelerated OpenGL. Without
this patch some elements are rendered without textures.

There is currently a problem when switching to the main
Half-Life menu. If you are running in OpenGL you will not be able
to re-enter the game loop unless you exit the game completely and
start it again.


Heretic II
==========
Palette textures must be disabled in these games when using
hardware accelerated OpenGL.
