2.0     Adapter Installation

Adapter installation, while greatly simplified through the mach32 INSTALL
utility, requires a step by step methodical approach to ensure that the
adapter does not conflict with other system resources and that it will
provide optimal performance.

The following technical information is a basic outline of the steps required
to install a mach32 graphics adapter.

1)  The mach32 requires port addresses 2E0-2EF and 3A0-3DF.  It also uses
    C0000-C7FFF for VGA BIOS.

    Check the system hardware for internal modems, FAX cards or LAN cards
    which may be using addresses at COM4 (2E8) or addresses between the
    range of 2E0 to 2EF.

    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.

2)  Review your CONFIG.SYS file to determine if a Memory Manager device
    driver is being loaded.

    Memory Manager device drivers, such as EMM386, QEMM and 386MAX, may
    interfere with the installation software and should not be loaded
    until the mach32 graphics adapter has been completely installed

3)  After powering down your system, remove your old graphics adapter (or
    disable the on-board graphics controller) and plug-in the mach32.

    Connect the monitor cable and mouse cable (if applicable) to the
    mach32 card and power-up the system.

    NOTE: Not all mach32 cards have built-in Mouse ports.

    If the system fails to produce text on the monitor, return to Step 1
    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 mach32
    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 mach32 EEPROM.

    NOTE: The screen will flicker for a few seconds during a configuration
	  change.

    If the INSTALL program returns to DOS and states that it could not find
    a mach32 based graphics card in the system, return to Step 3 to remove
    any memory manager device driver from your CONFIG.SYS file.

9.0	Driver Compatibility

The mach32 accelerator supports more software drivers than any other
graphics card. This flexibility means that the mach32 accelerator is
compatible with virtually any software application right out-of-the-box.
The supported drivers are:

*       mach32
*       VGAWONDER+
*       IBM VGA
*       VESA Super VGA

These drivers differ by the degree of acceleration, resolution and colors
supported.


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

10.0	 Turbo Application Interface

The mach32 Turbo Adapter Interface (Turbo AI) is a programming interface
written exclusively for the mach32 accelerator chip. This AI provides
access to the mach32 graphics controller by providing a "call interface"
to programs performing display functions in the 8514/A-compatible part
of the graphics card. This Turbo AI is 100% compatible with the IBM 8514/A
adapter interface.

The Turbo AI is only supported on 2MB Graphics Wonder product. Attempting
to use the Turbo AI on a 1MB card may result in displays problems.

Any application that needs an AI will ask for a TSR (Terminate-and-Stay-
Resident) program called HDILOAD.EXE. This TSR is supplied on a diskette
that comes with your mach32 accelerator. Install this TSR only if you use
applications that specifically use an 8514/A adapter interface.

There are two categories of software drivers that support the IBM 8514/A
graphics adapter -- Direct-to-Registers and Adapter Interface. They are
described as follows:

Direct-to-Registers:
The direct-to-registers driver writes directly to the registers of the
graphics controller. Examples of such applications are MS Windows and
IBM OS/2 Presentation.

Adapter Interface
Many applications access the 8514/A graphics controller using a software
interface called the 8514 Adapter Interface (AI). Examples are Lotus 1-2-3,
WordPerfect, and Turbo Pascal. These and many other applications use the AI
to eliminate the need for separate graphics drivers for different
applications. Contact your application program vendor for information on
AI support.


Installing the Turbo AI:
1.      Run the mach32 INSTALL program to bring up the Main Selection Menu.
2.      Select Install Adapter Interface from the menu.
3.      Although the AI files can be copied to any directory on the hard
	drive, certain applications require that the AI must be in a
	directory called \HDIPCDOS. We recommend that you accept \HDIPCDOS
	as prompted by the installation program. If this directory does not
	exist on the drive, one will be created. Press<Enter> to continue.
4.      Accept the Source (drive and directory) as prompted, or type in
	the location where these files can be found. Insert the appropriate
	disk and press <Enter> to start copying.
5.      The installation program attempts to modify your PATH statement to
	include the AI directory. It also attempts to add a line in the
	AUTOEXEC.BAT file so that the AI is loaded automatically on every
	power-up. Press <Y> if you want the AI in the PATH and automatic
	loading.
6.      When the AI installation is complete, press <Esc> to exit.

Using the Turbo AI:
If you prefer to load the Turbo AI manually, type:
C:\HDIPCDOS\HDILOAD\<Enter>
To unload the Turbo AI, type:
C:\HDIPCDOS\HDILOAD\UNLOAD<Enter>

Note
-  Application programs that use "AI" will display an error message if the
   AI is not present prior to starting the application.
-  The order of TSR program unloading (if you have more than one) from DOS
   memory is important. The last TSR loaded must be the first one you unload.
   Therefore, HDILOAD must be the last TSR loaded in order for you to unload
   it successfully.


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


11.0	 VGA Feature Connector

The VGA feature connector is provided on mach32 graphics accelerators
for the purpose of passing display information to optional add-in products
such  as TV or video playback (overlay) boards. The VGA feature connector
is limited to 640x480, 256 colors attempting a use a resolution or color
depth above that may cause display problems  

If the mach32 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).

When operating in Windows with the mach32 drivers, the driver must be 
directed to load the VGA palette on the overlay card.  This is 
accomplished by adding VGADAC=ON to the [DISPLAY] section of the SYSTEM.INI.

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

12.0	 Features Changes

- New VESA 75Hz Refresh Modes:

    ATI has adopted the 75Hz vertical refresh rate modes which have been
    recently standardized by the Video Electronics Standards Association
    (VESA).  Where applicable, these new modes will replace the previous
    76Hz modes at 640x480, 800x600 and 1024x768 and the 74Hz mode at
    1280x1024.

    In addition, new 90Hz and 100Hz modes are now supported on 2MB VRAM
    mach32 graphics cards. To access these new modes, use the following
    procedure:

    To access any of these modes, use the following steps:

    1.  Run the "INSTALL" program by inserting Disk #1 of the supplied mach32
	disks into the appropriate disk drive and run the INSTALL program.
    2.  From the Main Selection Menu, select Set Power-Up Configuration
    3.  Under the Set Power-Up Configuration menu, select Monitor Type
    4.  Under the Monitor Type menu, select either:
	    VESA standard 75Hz
	    High-Refresh  90Hz
	    High-Refresh 100Hz

Note:   90Hz and 100Hz selections apply only to current 2MB VRAM mach32
	graphics cards. Refer to the attached Mode Tables for supported
	resolutions and color depths.

    5.  Save your monitor selection by pressing <F10>
    6.  From the Main Selection Menu, re-select Set Power-Up Configuration
    7.  Under the Set Power-Up Configuration menu, select Monitor Type
    8.  Under the Monitor Type menu, select the Custom... option
    9.  For each resolution, you must specify the vertical refresh rate.
	You will notice that the refresh rate which you have specified in
	step 4 will now be listed as an option, if it is available at that
	resolution.

WARNING!   If the box outline in the Adjustment Screen becomes scrambled,
	   press < Esc > immediately to exit, then try a lower refresh rate.

For further information on using the Custom option, refer to the Monitor
and Video Modes chapter of your User's Guide.

Note:      Your existing refresh rates will remain unchanged (i.e. may
	   continue to use 74 or 76Hz refresh) until you re-run INSTALL
	   and select and save a new Monitor Type under Set Power-Up
	   Configuration.


- VDIF.EXE Utility:

    VDIF files are monitor definition files which conform to the VESA Display
    Information Format.  They define parameters which provide optimal
    resolution and refresh rate for the specified monitor.  If your monitor
    type is not already defined in the monitor list of the mach32 INSTALL
    program, having the VDIF file for your monitor will save you time.
    Please note that VDIF files are provided by your monitor manufacturer and
    they may not be available for all makes and models.

    VDIF.EXE is a mach32 software utility which takes a VDIF monitor
    definition file and converts it into an entry in the monitor list
    of the mach32 INSTALL program.  For complete instructions on using
    VDIF.EXE, consult README.VDI in your mach32 Utilities subdirectory
    (default is C:\MACH32).

- Memory Aperture:

    The Memory Aperture is not user configurable on ISA mach32 product.

- Accelerated Video Playback:

    ATI Multimedia Video Acceleration now supports the accelerated
    playback of video clips based on the following compression schemes:

	Intel Indeo 2.1
	Intel Indeo 3.1
	Microsoft Video 1
	Microsoft RLE
	Cinepak
