Introduction

The purpose of this document is to outline ATI Technologies Inc.
position regarding the use of Microsoft Windows 95 and our graphics
accelerator products.  This document will answer commonly asked questions
as well as explaining how to get your ATI products to operate under
Windows 95.

Generic Windows 95 Information

What ATI graphics accelerator products will work with Windows 95?

Drivers for all ATI graphics products, including all mach64, mach32,
mach8 and Super-VGA-based products, are included in Microsoft Corp.'s
official Windows 95 release.
These drivers offer up to a 10% increase in graphics acceleration
performance with enhanced features such as an integrated user interface,
context sensitive help Wizards and a customizable settings and features
page that will allow for greater ease of configuration of your ATI
graphics board.  In our October release, ATI will add features such as
MPEG support and color correction.

What resolutions and color depths are available with these drivers?

The Windows 95 display panel has the ability to select and/or change
resolutions to reflect the capabilities of the ATI graphics accelerator
installed in your system.
Windows 95 can dynamically select the resolution without having to 'reboot',
but a change in color depth (16bit to 24bit, for example) will require
an operating system reboot.

What enhancements do the Windows 95 drivers found on the CD-ROM provide
over the Windows 3.1x drivers?

Along with the inherent ease of use and features of Windows 95, ATI's
graphics drivers offer rock solid stability that is designed for the
Windows 95 'look and feel' and is fully integrated into the daily operation
of the operating system. Key features of the Windows 3.1x drivers have
been updated to reflect the new capabilities of the Windows 95 operating
system and have been optimized to provide up to a 10% performance increase.
ATI will also be updating the Windows 95 drivers in October to allow for
MPEG and accelerated games support and to add more features not normally
found in a video driver.

Can I use the existing Windows 3.1x utilities under Windows 95?

The previous mach64 drivers, FlexDesk+ and WinSwitch were designed for
the capabilities of Microsoft's Windows 3.1x and will not work with
Windows 95.  The ATI-specific drivers which ship on the CD-ROM disk or
update drivers from ATI (v1.01) should be used, as you will find these
drivers are faster and more stable under Windows 95.

Which ATI accelerator graphics cards are 'Plug and Play' certified?

Currently, ATI has received 'Designed for Windows 95' logo and 'Plug
and Play' certification for the GRAPHICS PRO TURBO PCI card.  We have
submitted the GRAPHICS XPRESSION and WINTURBO PCI boards and expect
certification from Microsoft within the next 30 days.  Note that all
of ATI's graphics accelerator products do function under Windows 95.
The logo certification applies to 'Plug and Play' compliant cards only.
Our VLB and ISA-based products will work with Windows, but are not
currently 'Plug and Play' certified by Microsoft. In the majority of
cases, ATI's boards, even the non-PnP versions, will configure
automatically under Windows 95.

How is my card recognized by Windows 95?

Each ATI graphics accelerator product is uniquely recognized by Windows 95.
In the hardware registration listing, the ATI products will appear as
follows (CD ROM-based drivers):

Product                                         Driver implemented
VGA WONDER                                              VGA
8514-ULTRA, GRAPHICS ULTRA, GRAPHICS VANTAGE,           mach8
VGA WONDER GT
GRAPHICS ULTRA PRO, GRAPHICS WONDER,                    mach32
GRAPHICS ULTRA+
GRAPHICS PRO TURBO, GRAPHICS XPRESSION,                 mach64
WINBOOST, WINTURBO

On the  ATI utilities v1.01, you will find the following:
GRAPHICS PRO TURBO, GRAPHICS XPRESSION, ATI mach64 (macxw4)
WINBOOST, WINTURBO

Does Windows 95 have DPMS support?

ATI's mach64-based products all support DPMS.
To enable DPMS support, use the Settings page of the Display Properties
sheet and select the "change display type" dialog box.  Next, set the
"monitor is energy star compliant" box in the "monitor type" area on
that page.

What support does ATI offer for games acceleration under Windows 95?

ATI is currently supporting the most recent version of Microsoft's
'DirectDraw' SDK, which is the key component of the next generation of
games that will appear for the Windows 95 platform.
The next generation of games promises to provide higher resolutions (4x),
faster (up to 60fps animation) and more brilliant colors than your typical
Sega(tm) SNES(tm) system!  Games of this caliber are expected to arrive
on store shelves by the end of this year.

Do your Windows 95 drivers have OpenGL support?

OpenGL is not part of the initial release of Windows 95 but is expected
to be implemented in future releases of Windows 95.  ATI does support
OpenGL in our Windows NT video acceleration drivers for the mach64-based
products.

ATI mach64 Specific Information

What drivers should I use for the mach64 series?

Windows 95 automatically recognizes the ATI graphics accelerator products
when installed right from the Windows 95 CD-ROM disc.  By using the v1.01
enhanced drivers, users of an ATI mach64-based graphics accelerator, such
as the GRAPHICS PRO TURBO, GRAPHICS XPRESSION or WINTURBO, can achieve
a greater magnitude of capabilities and ease of use.
With the Enhanced Utilities available in October, ATI has developed enhanced
mach64 drivers and user interface panels designed to offer high performance,
additional flexibility, and features not otherwise available under Windows 95.
ATI's Enhanced Utilities offers this functionality through additional
Windows 95 properties pages, which, for example, allows users of an ATI
mach64-based graphics accelerator, to easily manipulate their graphics
environment.

When will the new mach64 drivers be available?

ATI's graphics accelerator drivers ship with the Windows 95 operating system.
The enhanced graphics acceleration drivers (v1.01) specific to the mach64
graphics accelerator products will be available on August 24.  The next
major driver utilities release is scheduled for October.

Where can I get the new mach64 drivers?

ATI's mach64 driver updates may be downloaded from the ATI Download BBS
at (905) 764-9404 (14400, 8, N, 1), via the ATI FTP site at
ftp://ftp.atitech.ca, and from ATI's forum on CompuServe at GO ATITECH.
Fax info: (905) 882-2600 (touch #2).

What features do the mach64 Windows 95 video drivers offer?

Standard drivers that ship with the Windows 95 CD-ROM (or diskettes):
* Display properties sheet that includes basic screen properties
  capabilities such as, background settings, screen saver (DPMS support),
  appearance and settings.
* Settings provide the ability to manipulate the display area (resolution
  for display size), bit depth and font size, which are dependent on the
  capabilities of the graphics accelerator card used, and the monitor
  attached.
ATI mach64 Utilities v1.01 adds the following features to the basic
Windows 95 capabilities:
* Monitor Adjustment: Position and size adjustment of the Windows 95
  desktop on the display monitor, refresh rate selection, ability to use
  timing information specific to the monitor selected by the user
  (provides greater enhancement and clearer viewing) and the ability to
  select specific display refresh rates.
* Low Level Hardware Configuration: Ability to select the power-up video
  mode of the graphics adapter (the mode that the adapter will be set to
  after the computer is powered-up or reset).  Color and Monochrome modes
  are supported.

ATI mach64 Enhanced Utilities to be released in October will include :
* A Settings Page that allows for customization of desktop settings such
  as desktop size, display resolution and color depth, ability to
  user-customize pre-set display preferences.
* A Panning Page that allows the user to set up hotkeys to control panning
  of the desktop within a virtual desktop.
* A Screen Adjust Page for adjusting the size and position of screen
  images along with manipulation of the display's refresh rate.
* A Color Correction Page to allow the user to correct for color tone
  differences between real color values and the way the monitor
  displays them.  Control includes color spline, gamma correction and the
  ability for user-customized preset preferences.
* On-line documentation and context-sensitive help using the Windows 95
  Help Wizards.

Do the ATI mach64 drivers allow me to use special Windows 95 cursor and mouse features?

Yes.  ATI's mach64 drivers fully support both pointer trails and the
animated cursors.  Both of these features can be selected in the
Properties Page via the Mouse/Pointer settings.  Note that the mouse
drivers from the Windows 95 CD-ROM disc are required for use of this feature.

I used to have 'WinSwitch' with Windows 3.1x... do I still have this capability with Windows 95?

Windows 95 does not support 'hot-switching', which was available in
Windows 3.1x.   ATI's Windows 95 drivers (both CD-ROM version and v1.01)
currently do not provide the ability to hot-switch between color depths.
You can hot-switch between resolutions via the Display Properties sheet.

What is the ATI icon on the task bar for?

As a unique feature of the Enhanced utilities driver (due October), ATI
will offer users a 'shortcut' icon on the Windows 95 taskbar for instant
access to the display settings. The icon will allow the user to select
(by clicking the right mouse button) a menu that will present the user
with four options: Launch the On-line Help, Launch a Trouble Shooting
Help session, Select a desktop scheme (resolution, virtual desktop size,
font size, color depth), or Select a Color correction scheme.

Is DDC-1 and DDC-2b support still available if I install Windows 95?

Yes.  Our mach64-based products which have built-in DDC-1 and DDC-2b
support  will still be available to operate with all versions of the
Windows 95 ATI mach64 drivers.  If you have a DDC -1 or DDC-2b compliant
monitor, those boards will take advantage of it and help to configure the
optimum refresh rate and synchronization.

Do your Windows 95 drivers have additional hardware video acceleration support?

Currently, ATI's basic and initial (v1.01) Windows 95 drivers do not have
any additional hardware video acceleration support. ATI will offer this
support for Indeo-based video and MPEG-based video playback in a October
release of the Windows 95 drivers for the mach64-based graphics accelerator
products.  Other ATI products not based on the mach64 graphics accelerator
currently do not have video acceleration support.

What is required to play MPEG videos under Windows 95?

ATI will be releasing in October a software MPEG player designed for the
mach64-based graphics accelerator products for use under Windows 95.
The ATI Player(tm) supports Pentium-based MPC-3 compliant systems and is
strictly a software update that allows existing mach64-based boards to
take advantage of the MPEG-based videos on the market without the extra
expense of costly MPEG hardware boards.  The ATI Player provides full-motion,
full-screen video, excellent color quality playback and MPEG video playback
up to 30 frames per second.
The MPEG software is optimized for 8 bits per pixel (bpp) palletized and
16bpp modes, and features 1x zoom, 2x zoom and full screen playback.

How can we un-install the Enhanced mach64 drivers? 

ATI's drivers do not have the built-in ability to be uninstalled.  However,
users of Windows 95 who have installed the Microsoft Plus! software
(available from Microsoft as an add-on program) prior to the video driver
installation, can go into the Properties Page, select 'Add/Remove Programs',
and the driver installation will be listed on the lower menu.  Select this
and the driver will be removed, and your system will be reset to the driver
that Windows 95 detected upon initial installation.

Can VGA and Super-VGA drivers be used on mach64 and mach32 cards?

VGA drivers will work on mach32 and mach64-based products. Super-VGA drivers
will work on mach32-based products but will not work on the mach64-based
products.

5.0     Windows 95 mach64 enhanced display driver problems 
  
- The Windows 95 mach64 enhanced display driver is capable of using monitor 
   timing data contained within Windows 95. This data is selected by  
   configuring a monitor type at Windows 95 installation time or via the  
   "Settings" page of the display properties sheet. If you change the  
   selected monitor type via the "Settings" page of the display properties  
   sheet the new timing data may not take effect until after restarting  
   Windows 95. A solution to this problem is to always restart Windows 95  
   after changing the monitor type. 
 
 - The Windows 95 mach64 enhanced display driver is capable of using monitor 
   timing data contained within Windows 95. This data is selected by

   "Settings" page of the display properties sheet. The Windows 95 mach64  
   enhanced display driver may incorrectly interpret Windows 95 monitor  
   timing data for some older monitors which require interlaced modes.  
   This may cause some options to be disabled. A solution to this problem  
   is to select one of the "(Standard monitor types)" available via the  
   settings page of the display properties sheet. 
 
 - In Windows 95, display drivers can be installed via the "Add New 
   Hardware" wizard. When the Windows 95 mach64 enhanced display driver 
   is installed via the "Add New Hardware" wizard the "Settings" page does 
   not get installed into the mach64 display adapter property sheet. A 
   solution to this problem is to use the driver installation procedure 
   described above.
