                           SECTION 0 - GETTING STARTED

        The "Installation and Configuration" software package containing
        this readme file was extracted from the version 4.2 VGAWONDER XL24
        diskettes.  At the time of this writing, the following technote 
        was shipped with every copy of the XL24 disks:

============================================================================
ATI VGA Installation and Driver Diskettes
ATI Technical Note #079
February 18, 1994

ATI's VGAWONDER line includes a variety of graphics cards, based on
our 28800 and 18800 graphics controller chips.  VGAWONDER products
include:

VGAWONDER
VGAWONDER+
VGAWONDER+ 1MB
VGAWONDER XL
VGAWONDER XL24

VGA INTEGRA
VGABASIC-16

VGA CHARGER

VGA EDGE
VGA EDGE-16

VGA 88
VGA 640
VGA 800

VGA1024
VGA1024D
VGA1024DXL
VGA1024 XL
VGA1024A
VGA1024-16

All of these products are now supported by the VGAWONDER XL24
diskettes.  The installation software included can be used to
configure any ATI VGAWONDER product.  To get started, run the
VINSTALL program one disk #1.

Please note that the disks contain a variety of application drivers
which support the full range of video modes available on the
VGAWONDER XL24.  Only those modes which are supported by the
specific VGAWONDER hardware installed in your computer system will
function.  Check your ATI manual, or contact ATI Customer Support
for information on the capabilities of your ATI hardware.

In general terms, when a suitable analog monitor is connected to
the video card, the following conditions apply:

640x480 @ 16 colours    supported on all cards
640x480 @ 256 colours   minimum 512k video RAM
640x480 @ 32k colours   only on XL, XL24 and similar OEM products
640x480 @ 16.7M colours only on XL24 and similar OEM products

800x600 @ 16 colours    min. 512k RAM
800x600 @ 256 colours   min. 512k RAM
800x600 @ 32k colours   min. 1MB RAM, only on XL24 and some XL's

1024x768 @ 16 colours   min. 512k RAM see NOTE, below
1024x768 @ 256 colours  min. 1MB RAM

NOTE:  1024x768 @ 16 colours is implemented as mode 65h ("packed-
pixel" mode) on early VGAWONDER products (eg V3M series cards). 
Later revisions use mode 55h (a "planar" mode).  Most recent
software, such as Microsoft Windows 3.1, requires that this latter
mode be utilized by the graphics card.  If you find that your
VGAWONDER product will not display the 1024x768 @ 16 colours mode,
although it appears to meet the memory requirements, it may be that
your card is not capable of displaying mode 55h.


Determining the Capabilities of your VGAWONDER Hardware

Use the "Test Graphics Adapter" and "Show System Information"
functions in VINSTALL to determine the exact configuration and
capabilities of your graphics hardware.  Make careful note of the
name of the card, the BIOS Part Number, and the amount of video
memory installed.  These three factors will determine which video
modes are supported by a particular VGAWONDER hardware
configuration.

If you require assistance in confirming the capabilities of your
hardware, please contact ATI Customer Support with the name, BIOS
revision and amount of memory installed on your graphics hardware.


Specific Products

VGABASIC-16:  This is a 256K VGA product, that is restricted to the
standard IBM VGA modes.  The VGAWONDER XL24 disks should only be 
used to configure the BASIC-16's power-up video mode and monitor 
type.  Application software should be configured for IBM VGA when
using a VGABASIC-16.

VGA1024VLB:  This VESA Local Bus card is NOT supported by the 
VGAWONDER XL24 diskettes.  You will require special VGA1024VLB 
diskettes to install and configure this product.

VGAWONDER GT:  This entry-level ISA accelerator is NOT supported by
the VGAWONDER XL24 diskettes.  You will require special VGAWONDER GT
diskettes to install and configure this product.
============================================================================

        The  first program in this package you should get familiar  with
        is  VINSTALL.EXE.   It  replaces VSETUP,   VCONFIG,   V-INFO  and
        VGATEST  utilities in previous releases,   incorporating  various
        features,  e.g. setting power-up default configuration,   setting
        display   mode  dynamically,   and self-test  diagnostics.
        
        Unzip the VGAUTL archive into a directory on your hard disk.  

        Before  running VINSTALL,  make sure these lines appear  in  your
        CONFIG.SYS file on your boot disk:

             BUFFERS=20
             FILES=20

        You  may  require numbers higher than 20 if,   prior  to  running
        VINSTALL,   some applications already exist in memory,  using  up
        some  of the buffer and file handlers.  Remember to reboot  after
        modifying CONFIG.SYS.


                         SECTION 1 - DRIVER INSTALLATION

        Note that the display driver installation routines in VINSTALL will 
        not function correctly, since no drivers are provided in VGAUTL.ZIP.
        If you require drivers for a specific application, check the ATI
        BBS or Compuserve.


                             SECTION 2 - RAMBIOS.SYS

        RAMBIOS.SYS  is  a  RAM version of the  video  BIOS.  Note that most
        modern (386 and higher) systems allow you to "shadow" the video BIOS
        region using CMOS setup or a memory manager.  RAMBIOS.SYS performs
        a similar function for earlier PC, XT and AT systems that do not have
        this feature.  RAMBIOS is not generally recommend, although it may
        increase performance on early PC's.
        
        The driver takes up about 32K of conventional memory. To install it 
        in DOS, do the following:

                 a)   Copy RAMBIOS.SYS to your boot disk

                 b)   Create/Modify your CONFIG.SYS in your boot disk to
                      include the line:

                      DEVICE = RAMBIOS.SYS


        Notes:    The  above command must be executed before  any  device
        drivers  that replace the video interrupt, such as  ANSI.SYS  and
        FANSI  CONSOLE.  The  best place to put the  command  is  at  the
        beginning of the CONFIG.SYS file.


                             Section 3 - VANSI.SYS

        VANSI.SYS  is  a  device driver which is  a  substitute  for  the
        standard ANSI.SYS in DOS. Use VANSI only if you ned to use ANSI 
        functions in non-standard text modes (ie modes other than 80x25, 
        80x50 and 40x25 characters).


                               SECTION 4 - L43.COM

        L43  is  a   simple  program that  changes  the  number  of  rows
        displayed  on  the  screen.  This is  done  by  using  a  smaller
        character  font (8x8). The screen displays 50 lines in  VGA  mode
        and 43 lines in EGA mode.


                               SECTION 5 - CLR.COM

        The  program CLR clears any non-standard screen.  It is  intended
        for  text modes other than standard modes of 80x25, 80x50 or 40x25. 


                              SECTION 6 PRTSCRN.COM

        PRTSCRN.COM  is a program which enhances the function of the  DOS
        printscreen feature. Normally, when the contents of the screen is
        dumped  to a printer, only the first 80 columns and 25 lines  are
        printed. PRTSCRN allows the user to print any text modes that can
        be displayed on the video card,  including all non-standard  text
        modes.  It  does  not  enhance the dumping  of  graphics  to  the
        printer.

        PRTSCRN is a memory resident program. This means that after it is
        loaded  into  memory, it will remain there until  the  system  is
        reset or turned off. To load the program, simply run PRTSCRN.

        To  dump the contents of a text screen, hold down the  SHIFT  key
        and  strike  the PRINT SCREEN key (this key may be  marked  PRINT
        SCR, PRTSC or something similar).


                              Section 7 - VVESA.COM

        VVESA.COM  is a Terminate and Stay Resident (TSR) program. It  is
        the implementation of the VESA Super VGA BIOS Extension  Standard
        #VS911022-22.

        VVESA  is not a driver. It is a program which enables your  video
        board  to  be used with VESA compatible  software.  Consult  your
        software manual or your software manufacturer's Technical Support
        to see if a VESA driver is available for your software.

        Install your software for VESA Super VGA.  Then run VVESA  before
        running  your VESA compatible software.  If you prefer,  a  batch
        file  can be written to invoke VVESA and then your software.  The
        resident portion of VVESA only consumes a small amount of memory.
        
        To  remove  VVESA  from memory, type: VVESA OFF.

        Here is a list of VVESA advanced command line keywords:

             OFF: Remove the driver from the system memory.

             PAN: Enable Linear Address
                  It  allows  user  to pan or scroll  within  the  entire
                  display  memory. Standard VGA will wrap around  at  the
                  end of 64K in planar mode.  Linear address is  disabled
                  at default.

             55rw Force single page read & write mode
                  The Write Page number is set to Read Page number when a
                  display  mode is initialized.  (Note that only  display
                  controller  28800-5 or higher is default to  dual  page
                  mode,   i.e. the writeable and readable windows can  be
                  programmed independently)

             For  example,  to enable driver to view  display  memory  at
             upper 512KB, type:

                            VVESA PAN      <enter>

             Then run your VVESA application.


        The following VESA modes are supported:

             MODE      RESOLUTION        MEMORY    MEMORY
             NUMBER    /COLORS           REQUIRED  MODEL

             100h      640x400 /256      512KB     packed pixel
             101h      640x480 /256      512KB     packed pixel
             102h      800x600 /16       256KB     4-plane planar
             103h      800x600 /256      512KB     packed pixel
             104h      1024X768 /16      512KB     4-plane planar
             105h      1024X768 /256     1MB       packed pixel
             108h      80x60/16                    Text mode
             109h      132x25/16                   Text mode
             10Ah      132x43/16                   Text mode
             110h      640x480/32768     1MB       packed pixel
             112h      640x480/16.7 M    1MB       packed pixel
             113h      800x600/32768     1MB       packed pixel

        Note that some display adapters may not be capable of  displaying
        all  the  modes listed above.  Check the user's  manual  of  your
        display adapter for the available modes.

                            SECTION 8 - MOUSE DRIVERS

        There  are two mouse drivers; MOUSE.SYS and MOUSE.COM.  
        
        MOUSE.SYS is a device driver which is installed through the 
        CONFIG.SYS file on your boot drive.  This driver will activate 
        the mouse every time you boot the system. 
        
        The mouse driver can be installed manually by copying MOUSE.SYS  
        into the root directory of your boot drive and adding the following 
        line into your CONFIG.SYS file:

                  DEVICE = MOUSE.SYS [option(s)]

        MOUSE.COM is an executable program which is used to install a
        resident mouse driver if MOUSE.SYS is not installed and to con-
        figure the mouse driver.  To use MOUSE.COM,  type

                  MOUSE [option(s)]

        Available options are listed below:

        * Before installing:

                  MOUSE HELP     - displays help message on the screen.

                  MOUSE STATUS   - as above.

                  MOUSE ?        - as above.

                  MOUSE /?       - as above.

        * To Install:

                  MOUSE 3BUTTONS - Configures the mouse driver to 3
                                   buttons. This is the default unless
                                   2BUTTONS is specified.

                  MOUSE 2BUTTONS - Configures the mouse driver to 2
                                   buttons.

                  MOUSE 400DPI   - Configures the mouse driver for a
                                   high  resolution  (400dpi)   mouse.
                                   (Same as MOUSE /P1)

                  MOUSE 200DPI   - Configures the mouse driver for a
                                   standard resolution (200dpi) mouse.
                                   (Same as MOUSE /P3)

                  MOUSE /Pn      - Selects which profile to use.
                                   These movement profiles are ballistic
                                   curves. If the mouse moves faster for
                                   a given distance, the mouse pointer
                                   will move a longer distance across the
                                   screen. This driver comes with four
                                   movement profiles (1-Slow, 2-Moderate,
                                   3-Fast, 4-Unaccelerated). The default
                                   is profile 2 (Moderate).

                  MOUSE /Sn      - Sets the horizontal and vertical
                                   mouse-to-cursor movement sensitivity.
                                   The range is from 1 to 100.  Larger
                                   value will make cursor move faster.
                                   The default sensitivity is 50.

        * After installation:

                  MOUSE OFF      - Disables mouse driver. If MOUSE.COM
                                   was  installed instead  of MOUSE.SYS
                                   and MOUSE.COM was  the  last resident
                                   program installed, the memory occupied
                                   by the mouse driver will be released.

                  MOUSE          - Enables the mouse driver.

                  MOUSE STATUS   - Displays the current status of the
                                   mouse driver along with the help
                                   message.

                  MOUSE HELP     - as above.

                  MOUSE ?        - as above.

                  MOUSE /?       - as above.

                  MOUSE /Pn      - Selects which profile to use.

                  MOUSE /Sn      - Sets the horizontal and vertical
                                   mouse-to-cursor movement sensitivity.

        The  mouse  drivers are compatible with  Microsoft  Windows  3.1,
        including support for applications in DOS windows.


          SECTION 9 - INSTALLING 132-COLUMN IN WORDSTAR AND WORDPERFECT

        Both  WordStar  and WordPerfect can support the  132-column  text
        mode. No driver is needed, as both programs can be configured for
        this mode.

        WORDSTAR 3.31

        This  version  of WordStar must be configured  by  modifying  the
        WS.COM  file directly with the DOS DEBUG utility. This  operation
        should  only  be performed on the working version of  WS.  Follow
        these steps:
                       DEBUG WS.COM  <enter>
                       E CS:249  <enter>
                       84  <enter>
                       W  <enter>
                       Q

        Before  running the patched version of WordStar, put your  screen
        into 132-column mode using VINSTALL.

        WORDSTAR 4.0 AND 5.0

        These  versions  of Wordstar can be configured  for  132  columns
        using  the WINSTALL and WSCHANGE. Select 80x25 text in  WINSTALL.
        If  80x43 is selected in WINSTALL, it over-rides WSCHANGE.  Next,
        run WSCHANGE and select 132 columns and either 25 or 44 rows. Use
        VINSTALL  to put the screen into 132-column mode  before  running
        WordStar.

        NOTE: WordStar 5.0 doesn't restore the screen to 132-column  mode
        after exiting from the page preview feature. Be sure to save  the
        document before using the preview feature.

        WORDPERFECT 4.1 and 4.2

        WordPerfect  versions  4.1  and 4.2 allow you  to  designate  the
        number  of rows and columns displayed on the screen.  Wordperfect
        requires you to invoke any non-default text mode externally.

        To configure WordPerfect, type:

                    WP/S  <enter>

        A  setup  menu then appears. Select number 3 from  the  menu  and
        enter  the  desired  number  of columns and  rows.  There  are  3
        different text modes available with VGA card: 80x43, 132x25,  and
        132x44. Not  all of these modes are available with every monitor.

        After  Wordperfect is configured for the desired text  mode,  you
        must invoke it each time you use Wordperfect. The easiest way  of
        doing this is to make a batch file that invokes the required mode
        and then run WordPerfect.

        Create the file WP.BAT containing the following lines:

                    [command]
                    WP
                    VINSTALL CE80

        Where the line [command] is one of the choices shown below:

                    L43                 Invokes 80x43 or 80x50 mode.
                    VINSTALL M132x25    Invokes monochrome 132x25 mode.
                    VINSTALL C132x25    Invokes color 132x25 mode.
                    VINSTALL M132X44    Invokes monochrome 132x44 mode.
                    VINSTALL C132X44    Invokes color 132x44 mode.


        WORDPERFECT 5.0

        There is no need to do any special configuration with WordPerfect
        5.0  and 5.1.  Simply invoke the desired text mode with  VINSTALL
        and  run WordPerfect. WP automatically adapts to the  text  mode.
        Note  that  WP may not restore the screen to  132  columns  after
        exiting  from  the  page preview feature. Be  sure  to  save  the
        document before using the preview feature.


                           SECTION 10 - SIDEKICK PLUS
        
        Sidekick Plus version 1.00A has a problem in monochrome  graphics
        mode.  The  problem  occurs because Sidekick  Plus  restores  the
        screen  to graphics mode on exit if graphics is enabled.  If  the
        card  is in text mode instead of graphics mode, the  screen  goes
        blank.  As  a result, this program should not be  run  under  the
        monochrome  graphics mode. To use the program in  the  monochrome
        mode,  set  the  card to Monochrome Text  (MDA)  instead  of  the
        Monochrome Graphics (H720).


                            SECTION 11 - TTL MONITOR

        This  section  is  of  interest only  if  you  are  connecting  a
        monochrome  TTL monitor. The video card  automatically  optimizes
        the palette to obtain the maximum contrast when displaying  color
        software  on a monochrome monitor. This is highly desirable  with
        most  software  but it may cause certain animated  EGA  games  to
        blink. Some examples of these games are Gunship, F19 Stealth  and
        World  Tour  of Golf. If this occurs on a program  that  you  are
        using,  you  can disable or restore the  gray-scale  optimization
        with special VINSTALL commands.

        To disable optimization type this command:

                   VINSTALL MASK BA FF 40

        To re-enable optimization type this command:

                   VINSTALL MASK BA BF 0
