1. 3Dfx Windows Display Support
---------------------------------

This 3Dfx Windows Display Support release provides display drivers to
support 3Dfx display controller hardware features when used with
Microsoft Windows 3.1 or higher.  The Windows for Workgroups and
Windows for Pen Computing variants of Windows 3.1 or higher are also
supported.

To install the drivers, run 3fxSETUP.EXE as a Windows application from
within Windows.  See sections 3 and 4 of this file for more information
on installation and configuration.

3fxSETUP detects the 3Dfx hardware currently installed in your system
and allows you to select the features you wish to install.  Features
supported by the files in this release are:

    3Dfx Windows Display Drivers

The Display Drivers provide enhanced support for 3Dfx display
controllers.


2. Supported Display Controllers, Modes, and Monitors
-----------------------------------------------------

The 3Dfx display controllers supported by the display drivers in this
3Dfx Windows Display Support release are:

    3Dfx Velocity 100/200

NOTE: The 3fxMODE.INI contains the display mode information used by the
      3Dfx Windows display drivers.  This file should not be modified
      by the user.  Modification of this file could result in the
      corruption of your display driver configuration.  Should this
      occur, you will have to reinstall 3fxMODE.INI with 3fxSETUP.EXE to
      correct the problem.

NOTE: The 3Dfx Windows display drivers require a 386 or higher
      processor.

NOTE: A wide variety of third party monitors are supported by the
      display drivers in this release.  One of these monitors can be
      selected when installing or configuring with 3fxSETUP.  It may be
      necessary to manually size and center the image when using a
      third party monitor.

NOTE: The 3fxMON.INI contains the monitor information used by the
      3Dfx Windows display drivers.  This file should not be modified
      by the user.  Modification of this file could result in the
      corruption of your display driver configuration.  Should this
      occur, you will have to reinstall 3fxMON.INI with 3fxSETUP.EXE to
      correct the problem.


3. Installation and Configuration Using 3fxSETUP.EXE and 3fxSETUP.CPL
---------------------------------------------------------------------

The 3fxSETUP.EXE 3Dfx Windows display driver installation program
must be run as a Windows application from within Windows to install the
3Dfx Windows display drivers.

If your system has Microsoft Windows preinstalled:

    To run 3fxSETUP.EXE, pull down the 'File' menu from within the
    Program Manager or File Manager.  Select 'Run...' from the 'File'
    menu.  At the 'Command Line' prompt, type the following:

      C:\WINDOWS\OPTIONS\3fxSETUP

    and press ENTER.

If you are using 3Dfx Windows Display Support on diskettes:

    To run 3fxSETUP.EXE, insert the 3Dfx Windows Display Support
    diskette 1 into drive A:.  Pull down the 'File' menu from within the
    Program Manager or File Manager.  Select 'Run...' from the 'File'
    menu.  At the 'Command Line' prompt, type the following:

      A:\3fxSETUP

    and press ENTER.

Context-sensitive help is available within 3fxSETUP.EXE by clicking on
the 'Help' button.

3fxSETUP detects the 3Dfx Graphics Adapter currently installed in your
system.  It allows you to select the features you wish to install or
configure from the Setup Options dialog.  Features supported are:

    3Dfx Windows Display Drivers

3fxSETUP.EXE installs the display drivers and their necessary support
files, including 3fxSETUP.CPL, the 3Dfx Windows Display Driver
Configuration Utility.

After the 3Dfx Windows display drivers have been installed, the
configuration (resolution, number of colors, etc.) may be changed by
running the Configuration Utility.  This is done from the Windows
Control Panel by double-clicking on the icon titled 'Display', or by
pressing the ENTER key while this icon is highlighted.

Context-sensitive help is available within the Configuration Utility
by clicking on the 'Help' button.


4. Recovering from an Invalid Display Driver Configuration
----------------------------------------------------------

Because 3fxSETUP.EXE and 3fxSETUP.CPL are Windows applications that run
under Windows, you could have difficulty reconfiguring or reinstalling
the 3Dfx Windows display drivers if the current display driver
configuration is invalid.  When the display driver configuration is
invalid, Windows is unable to run, and thus you are unable to run
3fxSETUP.EXE and 3fxSETUP.CPL under Windows.  There are many things
that can cause an invalid display driver configuration.  One of the
most common causes is switching to a monitor that does not support the
currently configured resolution or vertical refresh rate without first
running 3fxSETUP.CPL to select the new monitor.

The key to recovering from an invalid display driver configuration is
to temporarily reconfigure Windows to use the standard VGA display
driver.  You can then run Windows and run 3fxSETUP.CPL from the Windows
Control Panel.  You can then specify a valid configuration and select
to restart Windows.

Even though 3fxSETUP.EXE is a Windows application, it supports a
command line option when it is run from the DOS command prompt to reset
the Windows display driver configuration to use the standard VGA
display driver.

If your system has Microsoft Windows preinstalled:

    Type the following from the DOS command prompt:

      C:\WINDOWS\OPTIONS\3fxSETUP /VGA

    and press ENTER.

If you are using 3Dfx Windows Display Support on diskettes:

    To run 3fxSETUP.EXE, insert the 3Dfx Windows Display Support
    diskette 1 into drive A:.  Type the following from the DOS command
    prompt:

      A:\3fxSETUP /VGA

    and press ENTER.

Alternatively, you may run Windows Setup (SETUP.EXE) from the DOS
command prompt and select 'VGA' for the 'Display' setting.


5. Updating Existing Drivers
----------------------------

Existing 3Dfx Windows driver installations can be updated to the
drivers contained in this 3Dfx Windows Display Support release by
running 3fxSETUP.EXE (from diskette 1, if you are installing from
diskettes) and installing the new drivers on top of the old drivers.
The actual installation can be performed by 3fxSETUP.EXE.

3fxSETUP.EXE will detect if you are updating existing drivers.  You
will be prompted to specify if you wish to delete the obsolete drivers
and OEM*.INF files.  It is recommended that you select to delete these
files.

The obsolete driver and OEM*.INF files you should delete from your
Windows SYSTEM directory are:

    3fxVDD.386
    3fxVGA.GR2
    3fxVGA.GR3
    OEM*.INF

NOTE: If you do not delete the obsolete OEM*.INF files, you will see
      duplicate and extraneous lines in the Windows Setup display driver
      list box and you might select an invalid display driver
      configuration.

You may also delete the following settings from the [Display] section
in the 3Dfx.INI file in your Windows installation directory, as they
are no longer used by the drivers in this 3Dfx Windows Display
Support release:

    DACMode
    Refresh
    Resolution
    Resource

NOTE: No problems are caused by not deleting these settings from
      the [Display] section of the 3Dfx.INI file.


6. Network Installation
-----------------------

3fxSETUP.EXE directly supports installing the 3Dfx Windows display
drivers on a network installation of Windows.  A network install
requires two steps:

    1. The network administrator must run 3fxSETUP.EXE as a Windows
       application from within Windows with the '/N' command line
       option:

       3fxSETUP /N

       3fxSETUP.EXE will verify the network Windows installation and
       copy over all of the driver support files.

    2. The user must run 3fxSETUP.EXE (without the '/N' command line
       option) on his network node system.  The installation process
       proceeds as described in section 3 above, with the following
       exception.  If there are driver files missing from the network
       Windows directory, then an error box is displayed explaining the
       steps that need to be performed by the network administrator
       before the installation can be completed (it is necessary to run
       3fxSETUP.EXE again in this situation).


7. High-Address Driver Issues
------------------------------

The 3Dfx QVision optimized 256-color, true color, and high color,
Windows display drivers, 3fxHV308.EXE, 3fxHV316.EXE, 3fxHV332.EXE,
are high-address drivers (high color currently not supported).
These drivers provide the high-performance
256-color mode support and 32K, 64K, and 16.8M color mode support.
A high-address driver accesses the display controller frame buffer
using a single contiguous range of addresses residing above the 1 MB
address boundary.  This is more efficient than low-address access,
because there is no driver bank-switching overhead incurred in order
to access the entire frame buffer.


8. 3Dfx.INI File Settings
----------------------------

The 3Dfx.INI file in the Windows directory contains settings that
control the configuration of the 3Dfx Windows display drivers and
autoloader.  The 3Dfx.INI file is created by 3fxSETUP.EXE during
installation and modified by 3fxSETUP.CPL during configuration.
Normally, the values of the settings written to 3Dfx.INI by
3fxSETUP.EXE and 3fxSETUP.CPL should not be modified by the user.
Incorrect modification of these settings could result in an invalid
display driver configuration.

There are some additional settings that may appear in the 3Dfx.INI
file that are not written or modified by 3fxSETUP.EXE or 3fxSETUP.CPL.
These settings control various low-level aspects of the display driver
and autoloader operation.  The list of these settings, their allowable
and default values, and the sections they belong in follows:

[Display] Common 3Dfx Windows Display Driver Section
------------------------------------------------------

Print=[ON/OFF | YES/NO | TRUE/FALSE]

    The drivers display a version and configuration information screen
    after being loaded by Windows and prior to initializing the display
    controller when the value of this keyword is one of the positive
    values.  Default = OFF.

    NOTE: Pressing Ctrl+C while the configuration information screen
    "Press any key" prompt is displayed will cause the driver to abort
    the loading process and Windows to return to the DOS prompt.
