Introduction
============
This Readme describes the above driver for the 3Dlabs Oxygen
VX1 board and Permedia3 boards.

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 95
• Intel Pentium II processor or later.

Install
=======
1. If you do not have a 3Dlabs CD or floppy disk set, then please
   proceed to the download instructions 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.

Driver Download Instructions
============================
1. Goto the 3Dlabs web site (at www.3dlabs.com) and locate the driver
   download page. Download the appropriate driver for your board.
2. Download the appropriate driver the zip file for your board into
   an appropriate 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
   above.
5. You can now delete the download scratch directory and its
   contents.

Changing display drivers
========================
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.


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:
640x480(100Hz)		800x600(100Hz)		1024x768(100Hz)
1152x864(100Hz)		1280x1024(100Hz)	1600x1200(85Hz)

The color depths supported in all the above resolutions are:
256 colors (Paletized)
High Color (16 bits per pixel)
True Color (32 bits per pixel)

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 (only available under Windows 98)
================================
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 now 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) 
==================================================
This driver release includes a new 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.

New Features and bug fixes
==========================

2106-0684R
----------
• Fixed AutoCAD problem with horizontal lines.

2106-0682R
----------
• Added support for Soft Engine bundle on Oxygen VX1.


General DirectX advice
======================

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.

To avoid this 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:	4.06.02.0436

and so you have DirectX 6 installed.

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


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

Start 3DStudio Max and go to the "File/Preferences" dialog box.
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 /3dsmax2/ directory (or
wherever you installed 3DStudio Max). If the file does not
exist then simply restart 3DStudio Max.

When running through OpenGL, 3D Studio Max 2 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.


Unreal
======
To use Unreal on Permedia3 or Oxygen VX1 with Hardware OpenGL
acceleration you need to select Tim's OpenGL renderer through
the Advanced Options menu. This is available in version 2.22
of the upgrade patch, available from the Unreal web-site.
You will then need to disable palette textures, which by
default are enabled:

Edit the file \unreal\system\OpenGlDrv.ini 
Under the [Default] section you will find an entry UsePalette=1
this must be set to 0. Without this change you will see
discolored textures when running the game.


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.


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


Known Anomalies
===============
• You need to ensure that Microsoft DirectX has been installed
  upon your machine to get the best performance from the 2D
  display driver.
• Applications which use Quicktime 2 will not run properly
  unless you change a line in the QTW.ini file in your Windows
  directory from OPTIMIZE=DRIVER to OPTIMIZE=BMP. See the
  Quicktime 2 release notes for more information about this.
