2.0     Adapter Installation

Adapter installation, while greatly simplified through the INSTALL
utility, requires a step by step methodical approach to ensure that the
adapter does not conflict with other system resources and to ensure
optimal performance.

The following technical information is a basic outline of the steps
required to install an ATI Rage Pro graphics adapter.

1)  Upon removing the ATI Rage Pro card from the box, record in your 
    User's Guide, the serial number (found on the non-component side of
    the card) and the BIOS version (located on a white label on a plug-in
    BIOS chip on the component side of the card).

    The serial number will be helpful if you require ATI Customer
    Support and will also be required to complete the Warranty Form.

2)  The following port addresses are used by the ATI Rage Pro:

    102, 1CE, 1CF, 2EC-2EF, 3?4, 3?5, 3?8, 3?9, 3?A, 3?B, 3DC
    and all aliases; 46E8 (?=B for monochrome, ?=D for color operations)

    Check the system hardware for internal modems, FAX cards or LAN cards
    which may be using addresses at 2E8 or any other I/O address used by
    the ATI Rage Pro.

    Also ensure that LAN cards, scanner cards and other peripheral adapters
    are not using upper memory addresses between C000 and C7FF.

    If you have a system containing an on-board graphics controller,
    consult your owners manual on how to disable it.

    Check and record how much system memory is installed on the system
    motherboard.


3)  After powering down your system, remove your old graphics adapter (or
    disable the on-board graphics controller) and plug-in the ATI Rage Pro.

    If the system fails to produce text on the monitor, return to Step 2
    and re-check the installed hardware for address conflicts.

    If no obvious conflicts are present, carefully remove all non-
    essential peripheral adapters (scanner, FAX/modem, audio, CD ROM cards,
    etc.) to determine the nature of the conflict.

    As a last resort, if possible, see if the card works in a different
    system.


4)  Once the system has properly booted, place Disk #1 of the supplied
    ATI Rage Pro disks into the appropriate disk drive and run the INSTALL
    program.

    The INSTALL program may report that it has found the graphics card to
    be in a "new or changed configuration".  If this message appears, press
    any key to have the INSTALL program update the ATI Rage Pro EEPROM.

    Also Install may report a conflict at I/O 2E8.  Refer to part 2 for
    possible conflicts.

    NOTE: THE SCREEN WILL BE BLANKED FOR FEW SECONDS DURING CONFIGURATION
    CHANGE.

    The INSTALL program also checks for potential system conflicts.  The
    "System Information" selection will list the graphics and system
    configuration details.  You can also run this option from command line
    by typing "INSTALL SYSINFO".

3.0     Installation Notes for OS/2

The ATI OS2 driver bundle consists of two disks: Disk1 contains the ATI OS2 Install
Program OS2INST, Disk2 contains the CID based ATI display driver. In a typical
installation process you'd want to configure your display modes as a first step,
then load your display driver as the second step. In the first step, Disk1 is used
to configure the display modes. Disk2 is employed in the second step to load the
display driver.

OS/2 DISPLAY MODE CONFIGURATION/CUSTOMIZATION

Note: The ATI configuration utility OS2INST must be run from VGA. If OS/2 is not
      configured with the VGA driver, start at step 1. If the VGA driver is already
      installed, go to step 5.

1)  Shutdown OS/2 and press "CTRL ALT DEL" to restart the system.
2)  At the "white block OS/2" message in the top left hand side of the screen 
    press "ALT F1".
3)  For Warp3 press "V" to reset the primary video display to VGA.  For Warp4
    press the "F3" function key.
4)  After the system comes up into OS/2 with the VGA driver, shutdown OS/2 again
    and reboot.
5)  Open an OS/2 Full Screen, insert Disk1 into floppy, switch to floppy and type
    OS2INST.
6)  From the Main Menu, select Quick Setup.
7)  From the Monitor Selection Menu, select the monitor that matches your monitor
    and proceed as prompted. For example, if a DDC monitor is connected, select
    DDC1/2B Monitor (see Note below). If non of the menu entries matches your 
    monitor, select "Custom...".
8)  When done with display configuration, exit ATI Install, remove Disk1 from floppy
    and follow the steps below to install the driver. 

Note: When a DDC capable monitor is connected and "DDC1/2B Monitor" is selected, 
      step 7 creates the configuration file EEDATA.EE_ in the root directory of 
      the system hard drive. The EEDATA.EE_ file contains the display mode information
      (EDID) read from the monitor.

OS/2 DRIVER INSTALLATION
1. Insert Disk2 into floppy and change to directory Os2.
2. Enter SETUPATI from the Os2 directory.
3. When prompted to select the Monitor Configuration, choose "Install
   Using Defaults for Monitor Type". Note: The screen will go blank momenteraly and may
   flash slightly while OS/2 determines valid display modes.
4. When done, shutdown and restart your system.
5. The OS/2 driver will first come up in 1024x768, 256 colors mode.  Use 
   the following steps to change the screen resolutions or number of 
   colors:

   a) Open 'OS/2 System' icon.
   b) Open 'System Setup' icon.
   c) Open 'System' icon.
   b) Select the 'Screen' tab.
   e) Select the desired resolution and number of colors from the list.
   f) Double click on the system menu icon or select close from the system 
      menu to close the window.
   g) Shutdown and restart your system.

When the system restarts is will be using the correct refresh rate. If not, 
confirm that the configuration file EEDATA.EE_ is located in root directory 
or your OS/2 hard drive.


OS/2 NETWORK MODE CONFIGURATION
The display modes can be configured over a network, assuming 
that the network is homogenous (i.e. the DDC monitors are identical, 
that is, they use the same EDID). If this is the case, then

1. Follow the above procedure to configure display modes and install 
   the driver in one of the network nodes. 

2. Copy the EEDATA.EE_ file generated on that node to the root
   directories of all the other nodes of the network to be updated.
   
3. Install the driver on the nodes to be updated as per OS/2 DRIVER
   INSTALLATION PROCEDURE above.

4.0     VESA Support

The VESA modes supported by your ATI Rage Pro card are dependent upon the
amount of video memory and the monitor type selected in the ADVANCED or 
QUICK SETUP. To determine the modes supported by your current configuration
you must install the ATI Rage Pro utilities, then run VESATEST from the ATI 
directory.

1) Run INSTALL and select "Utilities Installation" from the Main Menu.

2) Follow the screen instructions to completion.

3) When INSTALL is finished copying all necessary files, press <escape> to
   exit install.

4) Change directory to the \ATI (default) directory and type "VESATEST".

5) All the modes currently supported will be displayed.

If you experience problems using applications which support VESA, please
install the ATI Rage Pro Utilities and consult README.VBE for further
information.

****************************


5.0     VGA Feature Connector

The VGA feature connector is provided on ATI Rage Pro graphics accelerators
for the purpose of passing display information to optional add-in products
such  as TV or video playback (overlay) boards.  However, for VRAM-based
accelerators such as the GRAPHICS PRO TURBO 1600, GRAPHICS PRO TURBO and
WINTURBO, the feature connector only provides display information if the
ATI Rage Pro is placed in VGA mode.  This means that the user must select a
VGA or SVGA driver prior to running Windows, etc.

VRAM based products use an advanced 64-bit architecture in which the
data path from the VRAM connects directly to the DAC. This high performance
64-bit bus between the VRAM and the DAC provides for a substantially
increase in bandwidth for improved refresh rate support at higher
resolutions and color depths.  ATI Rage Pro drivers are written to operate
in accelerator mode and utilize the full capabilities of the dual-ported 
VRAM memory.  However, when operating in accelerator mode, the low bandwidth
VGA feature connector does not carry pixel information, and thus, overlay 
add-in cards connected to this feature connector will have no display or 
'black windows'.  To use the feature connector with VRAM-based products, a 
VGA driver must be used.

If the ATI Rage Pro is installed in a PCI slot, palette snooping must also 
be enabled.   This will ensure that the color palette on both the graphics
and overlay cards are properly initialized.  Refer to your system
documentation for instructions on how to do this (for many PCI motherboards,
the system CMOS provides a user accessible switch to enable palette 
snooping).

For DRAM-based ATI Rage Pro products such as the GRAPHICS XPRESSION and 
WINBOOST, the VGA feature connector can be used in both accelerator and VGA
modes. Due to the single-ported DRAM memory, data must return to the 
graphics chip and appear on the feature connector, regardless of the mode.
However when operating in accelerator mode, the ATI Rage Pro driver must be
directed to load the VGA palette on the overlay card.  This is accomplished
by adding VGADAC=ON to the MACX section of the SYSTEM.INI.

Note that if the ATI Rage Pro accelerator is installed in a PCI slot, 
palette snooping will also have to be enabled as described previously.

6.0  FEATURE.EXE and the VGA Feature Connector

FEATURE.EXE is a small utility that allows one to control the state of the
Video Feature connector on ATI264-CT based products only. The Video Feature
Connector resides on the Video card and is used by other peripheral cards
in the system to pass video information to and from the Graphics Adapter;
the link is achieved via a 24-pin ribbon cable that connects peripheral
cards and the video adapter in a daisy-chain fashion.

There are two modes of operation for the Feature Connector supported by
FEATURE.EXE:

  default - supports resolutions up to and including 800x600, AND refresh
        rates up to and including 75Hz.

  1024    - supports resolutions up to and including 1024x768, AND refresh
        rates up to and including 75Hz.

For example, if an user wants to enable pass-through at 1024x768 mode,
the syntax is :

    Feature 1024 <enter>

To install FEATURE.EXE:

1) Run the INSTALL program from the disk #1.

2) Select "Utilities Installation".

3) Follow the messages and once complete, FEATURE.EXE will reside in
   the \ATI default directory on your hard drive.

****************************

7.0  DMI support

To install the ATI DMI Component Instrumentation:

1) Ensure that DOS and Windows versions of DMTF are already installed. If
   not, please follow the instructions provided with the DMTF package.

2) Run INSTALL and select "Utilities Installation" from the Main Menu.

3) Follow the screen instructions to completion.

4) When INSTALL is finished copying all necessary files, press <escape> to
   exit INSTALL.

5) Change directory to the \ATI (default) directory and type "INSTDMI".

6) You may now use the DOS or Windows browsers to examine the current
   status of your video card.
