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.

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.

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