GRAPHICS ADAPTER DEVICE DRIVERS (GRADD)

_______________________________________


GRADD is an IBM OS/2* device driver architecture that makes it easier

to support new graphics hardware as it becomes available.  Enhanced PM

applications performance can be realized when using accelerated GRADD

drivers.


GRADD device drivers provide the ability to run WIN-OS/2 applications 

with OS/2 applications on the OS/2 Desktop. GRADDs also provide support

for accelerated and unaccelerated display graphics and advanced

color depth and resolutions. They conform to the OS/2 32-bit flat memory

model and are designed to function as 32-bit Presentation Manager*

graphics display drivers under the OS/2 32-bit graphics engine.


Several new and updated GRADD drivers are contained in this download,

including SciTech SNAP Graphics/se**.



GRADD DRIVERS INCLUDED

_____________________


The following accelerated GRADD driver is included:


    * SciTech SNAP Graphics/se**          (SDDGRADD)


which provides both accelerated and unaccelerated support for nearly

all common VGA and SVGA adapters (see list below). SciTech SNAP

Graphics/se** automatically detects your graphics adapter each time

during boot up.


Also included are IBM generic VGA and SVGA support:


    * Video Graphics Array GRADD          (VGAGRADD)

    * Generic VESA Unaccelerated GRADD    (GENGRADD)


These additional drivers are provided as backup drivers or for comparison

in case you encounter problems with the SciTech SNAP Graphics/se**.


GENGRADD may provide UNACCELERATED support for display graphics at enhanced

resolutions and colors depths.  GENGRADD will work with most adapters

that include a VESA compliant BIOS; and the performance, which will vary

depending on system configuration, will not be as good as an accelerated

driver. Similar legacy (VESA VBE) support is built into SciTech SNAP

Graphics/se**, and is automatically used when SciTech SNAP Graphics/se**

has no accelerated support for your graphics adapter.



ABOUT SCITECH SNAP GRAPHICS/se

______________________________


SciTech SNAP Graphics/se** is a version that IBM has licensed on behalf

of OS/2 customers. SciTech SNAP Graphics/se** contains a subset of the chip set

drivers contained in SciTech's full product which is called SciTech SNAP

Graphics Professional for OS/2.  You may find more information about SciTech

and their products on the SciTech web site (http://www.scitechsoft.com/).



LIST OF ALL SUPPORTED CHIPS

___________________________


This is a list of the various graphics adapters that this version of SciTech

SNAP Graphics/se** supports. The English language version of this README.TXT

file may have a more complete list than other languages. Please note that

this list refers to the actual chips being used, not board-level

implementations (Thus, no products from Hercules or STB are on the list, but

their products are supported because they use S3, Cirrus, Tseng, etc. chips).

Also, any adapter with less than 512KB of memory is not supported by SciTech

SNAP Graphics/se**.


Note: Please check the separate list of supported laptop chipsets for

      more information if you are using this product on a laptop. All

      laptop chipsets are still listed here as many laptop chipsets

      can also be used in regular PCI/AGP boards.

LIST OF CHIPS WITH DIGITAL FLAT PANEL SUPPORT

_____________________________________________


The following is a list of graphics chipsets that are working with digital

flat panels.  Other chipsets will work with flat panels in analog mode.

Please note that if you can't see anything on the display when you boot your

machine, SciTech SNAP Graphics/se** can't fix this, as it is a hardware

problem. Unless otherwise noted, the flat panel interface used is DVI.

Currently, modes available on digital flat panels are limited to those

provided by the video BIOS, which in most cases does not go higher than

1280x1024.


. ATI 3D Rage LT Pro (DFP), Rage XL (DFP), Rage 128 Pro, Rage 128 Ultra

. ATI Radeon, Radeon VE, Radeon 7500, Radeon 8500, Radeon 8500DV

LIMITED FEATURES

________________


There are currently three Limited Features of SciTech SNAP Graphics/se**:

TV Out, Zooming, and Multi-Head.  These features are called Limited Features

because they are not currently available on all graphics chip set hardware

for which a chip set driver could feasibly support such a feature.  For each

Limited Feature, we provided a list here of which chip sets SciTech SNAP

Graphics/se** currently supports with that Limited Feature.  For each Limited

Feature, additional chip sets may be added in the future.



LIST OF CHIPS WITH TV OUT SUPPORT

_________________________________


The following is a list of graphics chipsets that are working with TV Out.

Please note that if you can't see anything on the display when you boot your

machine, SciTech SNAP Graphics/se** can't fix this, as it is a hardware

problem. If you are using a laptop, you must use an external CRT monitor, as

the BIOS does not support TV Out display when the LCD panel is active.  Note

that the OS/2 boot messages will not display correctly on the TV; the text

mode used at that time does not work on TV screens, and SciTech SNAP

Graphics/se** has no control over this (it's not even active yet).


. ATI 3D Rage II+, 3D Rage IIC, 3D Rage Pro, 3D Rage LT Pro, Rage Mobility

. ATI Rage 128, Radeon, Radeon VE, Mobility Radeon, Mobility Radeon 7500

LIST OF CHIPS WITH MULTI-HEAD SUPPORT

_____________________________________


The following is a list of graphics chipsets that have support for MultiHead

display output. 


. ATI Radeon VE, Radeon 7500, Radeon 8500, Radeon 9000 Pro, Radeon 9200

. Matrox MGA-G450, MGA-G550

. NVIDIA GeForce4 MX 420, GeForce4 MX 440, GeForce4 MX 440 8X

. NVIDIA GeForce4 Ti 4200, GeForce FX 5200


Please note that there are some restrictions imposed for MultiHead:


1. Only CRT (15-pin VGA) output is supported for MultiHead at this time.

  You may need to use DVI->VGA connectors on some graphics cards.


2. You cannot use zooming when the desktop is in a MultiHead mode.


3. When the desktop is in a MultiHead mode and you change the MultiHead

  settings, you should reboot before switching away from the desktop

  (i.e. opening any fullscreen sessions), or your desktop will become

  corrupted.  The mouse cursor position may also be incorrect when you

  are running in this in-between state.


4. On Matrox chipsets, hardware mouse cursor and 256 color modes will not

  be available; these are hardware restrictions.


5. On Nvidia chipsets, 16M color modes wider than 2040 will not be

  available; this is a restriction of the NV1 interface.  Only cards

  where the video BIOS properly initializes both heads (in other words,

  it boots in clone mode automatically) are supported.




SUPPORTED RESOLUTIONS

_____________________


Supported resolutions, color depths and refresh rates are adapter dependent

and will vary depending on the amount of graphics memory and the limitations

of the graphics adapter hardware.



COMPATIBILITY

_____________


These graphics device drivers are currently compatible with:


      All versions of OS/2 3.0  with Fixpak level 35 or later

      All versions of OS/2 4.0  with Fixpak level  5 or later

      All versions of OS/2 Warp Server for e-business

      All versions of OS/2 Convenience Pak (MCP and ACP)


The SETUP installation command rejects installations on unacceptable OS/2

versions or Fixpak levels.


Also, after installing these graphics drivers, if you later wish to

uninstall any required Fixpak to a Fixpak level before Fixpak 5 (OS/2 4.0)

or Fixpak 35 (OS/2 3.0), you should first restore your computer to VGA to

remove the SciTech SNAP Graphics/se** drivers.


Other than the use of English messages, the SBCS drivers installed for SBCS

languages not in the SET LANG= list in the section entitled "Extraction"

above are correctly functional for the chosen language.



FUNCTIONAL RESTRICTIONS

_______________________


Current known restrictions include the following:


1) SciTech SNAP Graphics/se** generally only supports PCI and AGP graphics

  adapters, and does not support ISA, VLB and Microchannel. The only

  exception is for laptop chipsets that are on a non-PCI local bus, or

  early motherboard integrated chipsets such as the early MediaGX family.


2) The SciTech SNAP Graphics/se** drivers do *NOT* require a chipset specific

  SVGADATA.PMI file, but instead have a single PMI file implemented via a

  DLL. Hence when running SDDGRADD do *NOT* use the SVGA ON INIT command to

  create an SVGADATA.PMI file.


3) The IBM GENGRADD drivers, require VESA** compliant video BIOS (Version

  1.2 or greater) or an appropriate SVGADATA.PMI file to provide generic

  unaccelerated VESA support. For older non-VESA adapters with SVGA PM

  driver support from IBM, GENGRADD may often be used as an alternative

  SVGA driver set by following the GRADD Graphics BBS drivers SETUP

  installation command with the command "SVGA ON INIT" from an OS/2 or

  DOS Full Screen prompt to create an SVGADATA.PMI file, before rebooting

  to use the GENGRADD drivers.


4) If you enable the HPFS386 Local Security feature, you must make sure that:

    - The x:\os2\drivers\snap directory is always readable.

    - The x:\os2\drivers\snap\config subtree has read/write/create

      access for all users.

  Where "x:" is your OS/2 boot drive. Failure to do this will cause your

  system to not boot properly unless the administrator is logged on.


5) Any adapter with less than 512KB of memory cannot be supported by SciTech

  SNAP Graphics/se**.



APAR FIXES INCLUDED IN THIS DRIVER

__________________________________


Some fixed APARs may not be listed. If you received this driver through the

IBM OS/2 support channel and your requested APAR is not listed, please

install the driver, as your requested APAR is included.


..........................................................................




INSTALLATION...........................................................


PRELIMINARY STEPS

_________________


The following steps prepare your computer before installing the SciTech

SNAP Graphics/se** drivers:


1.  Other applications, particularly WIN-OS/2 applications, should be closed

    so that the device driver installation can replace the driver files

    which an open application might have locked as read only.


2.  If you previously installed an SVGA driver, return to VGA resolution

    using the procedures in the section of this README entitled "Setting Your

    Display to VGA Mode".




EXTRACTION

__________


To set up the SciTech SNAP Graphics/se** BBS driver installation directory,

do the following:


1.  Open an OS/2 full-screen or OS/2 window session.


2.  Before running the SNAPSE*.EXE self extracting zip file (the exact name

    depends on the release build number), change the current directory to the

    "installation directory" in which you wish to store the SciTech SNAP

    Graphics/se** BBS driver installation files. It should be something

    *other* than x:\snap, where "x:" is your boot drive. We suggest

    C:\BBS\SNAP. At the OS/2 command prompt, type the following commands:


    C:

    MD C:\BBS

    MD C:\BBS\SNAP

    CD C:\BBS\SNAP


3.  You may wish to copy the SNAPSE*.EXE self extracting zip file to the

    installation directory first. Then at the OS/2 command prompt, type

    the following command:


    SNAPSE* -DIR -OVER


4.  Use SET LANG= to set the correct language. The language may already be

    correctly set in your CONFIG.SYS.  If not, then at the OS/2 command

    prompt, type one of these SET LANG= commands to choose your language:


    SET LANG=ar_AA    for Arabic (English with Arabic graphics formatting)

    SET LANG=pt_BR    for Brazil

    SET LANG=zh_CN    for Simplified Chinese

    SET LANG=de_DE    for Germany

    SET LANG=da_DK    for Denmark

    SET LANG=es_ES    for Spain

    SET LANG=el_GR    for Greece (English with Greek graphics formatting)

    SET LANG=fi_FI    for Finland

    SET LANG=fr_FR    for France

    SET LANG=iw_IL    for Israel (English with Hebrew graphics formatting)

    SET LANG=it_IT    for Italy

    SET LANG=ja_JP    for Japan

    SET LANG=ko_KR    for Korea

    SET LANG=nl_NL    for Netherlands

    SET LANG=no_NO    for Norway

    SET LANG=sv_SE    for Sweden

    SET LANG=zh_TW    for Taiwan

    SET LANG=en_US    for English (default)


    Each language has its own copy of this README.TXT file, which may be

    translated from English, as well as other language dependent files.



5.  The SETUP command in the installation directory may then be used to

    install the proper language dependent files and configuration

    information from the install directory onto your boot drive.

    Running SETUP without any options will give brief syntactic help

    about the SETUP command (described later in detail in this README file)

    in your chosen or default language.  To see this help, at the OS/2

    command prompt, type the following command:


    SETUP



COPYING TO DISKETTES (OPTIONAL)

_______________________________



Once extracted to an installation directory tree, you may place the SciTech

SNAP Graphics/se** driver installation files on diskettes for backup or

transportation purposes using the OS/2 BACKUP command:


1. Open an OS/2 full-screen or OS/2 window session.


2. Type "BACKUP C:\BBS\SNAP A: /S" and press the Enter key.


3. Label and insert as many pre-formatted diskettes as required.


4. You can use HELP BACKUP to get more information about the BACKUP command.


To restore the same diskettes to the same or a different computer:


1. Open an OS/2 full-screen or OS/2 window session.


2. Type "RESTORE A: C:\BBS\SNAP /N /S" and press the Enter key.


3. Insert previously backed up diskettes as required.


4. You can use HELP RESTORE to get more information about the RESTORE command.


IBM and SciTech have made no provision for installing these drivers

directly from diskettes.




SETTING YOUR DISPLAY TO VGA MODE

________________________________


If your display is in sync and you otherwise have a usable Desktop, we

recommend that you use Selective Install to set your display to VGA mode.

Otherwise, use the following procedures to return to VGA mode.


    1.  Turn on your computer.  If your computer is already on, shutdown or

        press Ctrl+Alt+Del to restart it.

    2.  When a small white box appears in the upper left-hand corner of your

        screen, press Alt+F1.

    3.  When the Recovery Choices screen appears, press function key F3

        or the letter "V" depending on the operating system version.

    4.  Run Selective Install to change the Windows drivers.


Once the computer has booted, your display adapter is restored and can work

in VGA mode.  If you want to install a new display adapter or graphics

device driver, refer to the chapter entitled "Video Procedures" in the

User's Guide to OS/2 Warp.



ATTENDED INSTALLATION

_____________________


To do an attended install of the SciTech SNAP Graphics/se** drivers from the

self extracting zip file installation directory, do the following:


1.  Open an OS/2 full-screen or OS/2 window session.


2.  Before running the extracted SETUP.CMD file, use SET LANG= to set the

    correct language. The language may already be correctly set in your

    CONFIG.SYS.  The section of this README entitled "Extraction" gives

    examples.


3.  At the OS/2 command prompt, type the following command to copy all the

    required files to the OS/2 boot drive:


        <SrcPath>SETUP xxx [<SrcPath>] [<BootDrive>] [/u]


    Where:

        xxx is one of:


            "GEN"  - Generic VESA Unaccelerated GRADD

            "SDD"  - SciTech SNAP Graphics/se** GRADD

            "VGA"  - Video Graphics Array (VGA) GRADD


        <SrcPath> for SETUP is required if SETUP is not in the current

                    directory.


        [<SrcPath>] parameter is optional (required if next parameter

                    specified) and is the installation directory.


        [<BootDrive>] is optional and is the drive where OS/2 is installed.


        [/u] is optional and indicates an unattended install such as for

            CID installations.  A CID response file is not required.


    Then press Enter.


4.  When prompted to do so, shutdown, and then restart your computer.


    NOTES:


    1) During the installation of this driver, DISPLAY.LOG and DSPINSTL.LOG

      files are created or appended to in the OS2\INSTALL directory.  These

      files identify the OS/2 system files that were updated and indicate

      whether the installation was successful and reasons for failure.  The

      contents of these files might be useful if you need to report an

      installation problem to IBM.


    2) You may be prompted about whether you want to overlay certain files

      where the target file is newer than the source file. In general, you

      should answer YES to all the prompts unless you have previously

      experienced specific problems with the driver and are reinstalling it.


5.  After the computer reboots, the desktop should be in the 640x480x256

    display mode.  Do the following to configure correctly for your current

    display and choose an appropriate resolution and refresh rate:



    a.  Open the SciTech SNAP Graphics/se** folder, or open the OS/2

        System folder and then the System Setup folder.

    b.  Open the System object.

    c.  When the Settings notebook appears, select the Screen tab.

    d.  If you are using the SciTech Screen pages (SciTech SNAP Graphics/se**

        logo and driver information appears), your monitor setting will

        display.  If it is correct, then skip to step g.  Otherwise, select

        your monitor on Screen page 2.  The current version requires you to

        close the System object and reopen it in order to have your monitor

        selection affect the list of resolutions and refresh rates available.

        After you have done this, skip to step g.

    e.  If you are using the IBM Screen pages, the monitor should not be

        changed from "SciTech Display Doctor Monitor" on page 2. This will

        allow you to use all the resolutions and color depths that the

        SciTech SNAP Graphics/se** drivers support.

    f.  Open the Monitor Utility from the SciTech SNAP Graphics/se**

        folder, and select your monitor (see the next section).  The IBM

        Screen pages require you to shutdown and restart your computer in

        order to have your monitor selection affect the list of resolutions

        and refresh rates available.  However, if you know your monitor's

        limits, you may just continue, but limit your resolution and refresh

        rate selections accordingly.

    g.  Return to the System Properties Screen Page 1, and select your

        desired resolution, color depth, and refresh rate. Depending on your

        adapter and display, refresh rates may not be selectable.

    h.  Close the Settings notebook.

    i.  Shutdown and restart your computer.


6.  When you have completed the installation, all the SciTech SNAP

    Graphics/se** command line utilities will be located in the x:\snap

    directory, where "x:" is your OS/2 boot drive.  Most will also be found

    in the SciTech SNAP Graphics/se** folder on your desktop.




INSTALLATION IN A CID ENVIRONMENT

_________________________________


NOTES:


1.  Create a directory on the server (e.g. X:\BBS\SNAP) and extract the

    installation files from the self extracting SNAPSE*.EXE file to the

    X:\BBS\SNAP installation directory as described under the section

    entitled "Extraction".


2.  You must have OS/2 successfully installed on the client using the CID

    (Configuration Installation Distribution) method.


3.  To configure display selection, resolution and refresh rate, refer to the

    file "README.CFG" in this package.


To install a device driver using CID, use the following information to modify

RESTORING YOUR SYSTEM IN CASE OF FAILURE

________________________________________


If SciTech SNAP Graphics/se** does not correctly boot on your system, you can

easily switch back to the GENGRADD drivers to boot your system to a

workable state again. To revert to GENGRADD, do the following:


1. Boot to an Alt-F1/F2 command prompt mode.


2. Edit CONFIG.SYS file and change the line

      C1=SDDGRADD

    to

      C1=GENGRADD,SBFILTER

    Remove the line "DEVICE=x:\OS2\SDDHELP.SYS".

    Remove the line "SET VCFG_NO_DDC=TRUE".


3. Delete or rename the x:\OS2\SVGADATA.PMI file.


4. Shutdown and reboot your system.


If that fails you will need to revert to VGA mode and reinstall your

prior display drivers.



REMOVING SCITECH SNAP GRAPHICS/se

_________________________________


SciTech has included an uninstall program you can use to completely remove

SciTech SNAP Graphics/se** and all its components from your system. To remove

SciTech SNAP Graphics/se**, simply run the x:\SNAP\UNINSTAL.EXE program,

where x: is the OS/2 boot drive. This will remove all files, and revert your

system to VGA mode. From there simply reinstall your original display

drivers or GENGRADD or VGAGRADD.

ADVANCED OPTIONS........................................................



GAMON MONITOR SELECTION PROGRAM

_______________________________


For best results, the monitor should not be changed from "SciTech Display

Doctor Monitor" on Screen Page 2 when using the IBM version of the Screen

Properties in the OS/2 System object.


If you have a plug and play monitor, SciTech SNAP Graphics/se** will

automatically detect its capabilities. If your monitor is not detected, you

can configure it using the SciTech version of page 2 of the Screen properties

in the System object, or manually configure it using the GAMON utility. GAMON

is a simple program to allow you to select a monitor that is attached to

your graphics card. Selecting a monitor will filter the available display

modes and refresh rates depending on the capabilities of your attached

monitor.


If you use GAMON from the SciTech SNAP Graphics/se** folder, you should

leave off the "gamon" command name at the start of the following command

examples.  If you wish to use the command line version of this or other

SciTech programs, you may wish to add the path "x:\sdd" to your OS/2 command

search path, where "x:" is your OS/2 boot drive.


To display the current monitor configuration, use the following command:


  gamon show


To select a monitor you must know the manufacturer and model name for your

monitor. To list all available manufacturers, use the following command:


  gamon mfr


This will produce a rather long list, so you can narrow the list by entering

the start of the manufacturer name as below, and list all monitors that

manufacturer makes:


  gamon model nec


which will list all 'NEC Technologies' monitors. Once you have found your

monitor, you can select it by entering the partial manufacturer name and

a partial model name like so:


  gamon select nec xp21


which will select the 'NEC Technologies' 'NEC XP21' monitor.  If you need

to make a selection with spaces in the name, use the quoting characters:


  gamon select "NEC Technologies" "NEC XP21"


If your monitor is not listed, you can add it to the database.  The

majority of monitor manufacturers include INF files for Windows 9x with

their monitors, and/or provide them on their web sites.  You can import

these files using:


  gamon import <filename.inf>


where <filename.inf> is the name of the INF file.


Since the command-line program is a bit archaic, it is recommended that

you use the SciTech version of page 2 of the Screen properties instead.



GAREPORT HARDWARE REPORT PROGRAM

________________________________


This is a simple program which will load the SciTech SNAP Graphics/se**

driver for your hardware, and report the graphics hardware configuration.



GACTRL CONFIGURATION PROGRAM

____________________________


This program allows you to perform compatibility testing on the SciTech SNAP

Graphics/se** drivers, including testing the graphics modes, DPMS Power

Management and DDC communications.


One of the other useful things that this program can do is allow you to

adjust the centering and refresh rate control for all available display

modes (including text modes for OS/2 command prompts!). Use the 'Centering

and Refresh' menu item to change the refresh rate and centering values

for individual display modes, or the 'Global Refresh Rate' menu item to set

all display modes to a preferred refresh rate.


NOTE: Changing the global refresh rate *also* changes the refresh rate

      for VGA text modes to your preferred value. You may want to reset

      the text modes back to 70Hz manually if the refresh rate controlled

      text modes cause problems.




GAOPTION OPTIONS SELECTION PROGRAM

__________________________________


This is a simple command line program to allow you to override some of the

useful options for the SciTech SNAP Graphics/se** drivers. You will need to

reboot before any of the options will take effect for the SciTech SNAP

Graphics/se** drivers.


To see the current list of options and settings, use the following command:


  gaoption show


This will show all the options for the current device. Some of the more

useful options are explained below:


  gaoption accel [none | basic | most | full]


This option controls what hardware acceleration features are used by the

drivers. By default full hardware acceleration is enabled. If you have

problems with the mouse cursor, try 'most', which will disable hardware

acceleration of the mouse cursor. The 'basic' setting will allow for

basic acceleration features and is useful if you have problems with

line drawing or text. The 'none' option turns off all hardware

acceleration in the driver.


  gaoption vbe [on | off]

  gaoption vga [on | off]


These options control whether the VBE/Core or VGA fall-back drivers are

used by default, or whether the native hardware accelerated drivers are

used.  By default these options are off, but you may want to enable one

of them if the native driver has problems on your system.


  gaoption prefer32 [on | off]

  gaoption prefer16 [on | off]


The prefer32 option controls whether you would prefer 32-bit display modes

over 24-bit display modes to show up in the list of available display modes

for the SDDGRADD driver. The default is to choose 32-bit modes in preference

to 24-bit modes if the mode exists at both color depths, and both color

depths are fully accelerated. Otherwise the highest performance mode is

always chosen.  Similarly, the prefer16 option controls whether you would

prefer 16-bit display modes over 15-bit display modes, but all modes at both

of these color depths are always available for the SDDGRADD driver.


  gaoption nowcomb [on | off]


This option controls whether the SciTech SNAP drivers will attempt to

enable write combining on your system for faster system memory to video memory

transfers. By default write combining will always be used where possible,

but if this is causing problems you may wish to try using this option to

disable write combining support. The most likely scenario would be for

a new processor that has not yet been fully QA tested.


  gaoption agpmem [memsize]


This option controls how much system memory to allocate to video.  It only

has an effect on video chipsets that use AGP memory; currently the Intel

i810 and i815 chipsets are the only ones that do so.  The memory size

defaults to 4096 Kb, but can be changed as desired.


..........................................................................




MISCELLANEOUS TIPS.....................................................



BIOS Support on Laptops/Integrated Video

________________________________________


Some laptops, including those that use the S3 Savage/IX or S3 SuperSavage

chipsets, will require an additional driver for full LCD BIOS support on

older revisions of OS/2.  When booting with the LCD panel active, if the

OS/2 System object does not display refresh rate selection, and/or displays

video modes larger than your LCD panel, then you may need this driver.  You

can load this driver by adding the following line to your Config.Sys file:


  DEVICE=X:\OS2\MDOS\VPRPMI.SYS


where X: is your OS/2 boot drive, and reboot.  Note that subsequent

installations of GRADD drivers (including SciTech SNAP Graphics/se**) may

remove this line from your Config.Sys.  This driver should not be required

for the "Convenience Pak" releases of OS/2 Warp 4 and WSeB.


Machines that utilize shared memory for the on-board video chipsets, such as

the Intel i845G, will benefit from increasing the amount of allocated video

memory in the BIOS.  This can greatly increase the number of available video

modes and refresh rates.



Using the Analog Interface on Flat Panels

_________________________________________


Many flat panel LCD monitors have an analog VGA interface for backwards

compatibility.  Unfortunately, many of them do not function properly in all

modes when using this compatibility interface.  If you have a chipset which

is listed as having DVI support (and your hardware supports this), it is

recommended that you use this digital interface for optimum display output.

Otherwise, you may be able to improve the display output by using the image

adjustment features in the monitor menus.  Also note that some panels may

report modes greater than their native resolution when using the analog

interface; attempting to use these modes will not give satisfactory results.



Fixpak-Specific Problems

________________________


OS/2 Fixpaks contain updates to the core GRADD system, parts of which will

never be updated by SciTech SNAP Graphics/se**.  Therefore, updating to the

latest Fixpak can often clear up some graphics problems.  Unfortunately,

there are sometimes exceptions, and new problems appear.  If there are known

workarounds to these problems, we will try to list them here.


** Washed-out icons **


In Warp 4 FP14 and above, WSeB FP2, and the Convenience Paks, there is

new "enhanced stretch-blitting."  This new feature has one known ill

side-effect, where some of the icons for folders and other items will

appear "washed out" when running in 24bpp or 32bpp.  To fix this, you

can disable the new feature by adding the following line to your

Config.Sys file:


  SET ENH_STRETCH=NO


This setting will not take affect until after you reboot.


** Reverting to VGA in Warp 3 **


Using the revert to VGA function in Warp 3 will cause some video

components to be back-leveled to versions that are incompatible with

GRADD, most notably DSPRES.DLL.  If you use the revert to VGA function,

you should update your video components with the versions found in the

\OS2\INSTALL\VGA directory prior to installing SciTech SNAP Graphics/se**.



Relocating the SciTech SNAP Graphics/se drivers

_______________________________________________


If you are limited on disk space on your boot partition, it is possible to

relocate the SciTech SNAP Graphics/se** drivers, which are normally located

in the subdirectory \OS2\DRIVERS\SNAP, to another drive.  Create a new

directory to hold these files, such as D:\SNAP\DRIVERS, then use xcopy to

copy all files, including all of the subdirectories, from the original

location.  Then, add the following line to your Config.Sys file:


  SET SNAP_PATH=D:\SNAP\DRIVERS


where D:\SNAP\DRIVERS is the new directory that you created.  Then, you may

remove the files from the original location, and reboot.



Switching between Screen Pages

______________________________


If for some reason you wish to disable the new SciTech SNAP Graphics/se**

Screen pages in the System object, it is possible to revert back to the IBM

version by running the following command:


  C:\SNAP\SDDVCFG.CMD R


where C:\SNAP is the directory that you installed into. To (re-)install the

SciTech versions of the Screen pages, simply run it without parameters:


  C:\SNAP\SDDVCFG.CMD


where C:\SNAP is the directory that you installed into.


..........................................................................
