1) How to install HydraVision
================================================================
To install downloaded HydraVision software for WinNT or Win95, please
make a copy of your driver disk and perform steps a and b.
(a) Unzip the downloaded zip file to a floppy disk using
PKUNZIP (available on the www.pkware.com site).
A typical PKUNZIP command will look like this -
"PKUNZIP V200.ZIP A:\" where V200.ZIP is the name
of the downloaded zip driver file and A: is your
floppy drive. This floppy disk will be your new
install disk. You can also use Winzip under Windows
to unzip your files (available at www.winzip.com).
(b) Follow the HydraVision installation instructions in
your Jeronimo User's Guide using your new install disk.
2) How to contact Appian
================================================================
Appian Technical Support may be reached at 1-800-422-7369
Appian Sales may be reached at 1-800-727-7426
Appian on the internet is available at http://www.appiangraphics.com
3) DirectDraw Support - IMPORTANT!
================================================================
Appian has improved DirectDraw support in Win95 while running
dual monitors. DirectDraw is also supported under NT 4.0.
Specifically, Appian supports the following DirectDraw operations:
- Exclusive Mode (where DirectDraw takes over the entire
screen). Jeronimo supports this mode with no issues.
- Windowed Mode (where DirectDraw plays back in a window).
Jeronimo supports this mode as long as the DirectDraw window
is fully contained on one screen. If the DirectDraw
window is moved onto a monitor split, Jeronimo will not
process DirectDraw commands until the window is moved to a
single screen. When running Active Movie, this will
result in a paused video screen. Note that some DirectDraw
applications running in this mode may cause errors when their
window is dragged to another screen. Also note that when
an active DirectDraw window is dropped on the split, your
mouse response will become sluggish and some screen degradation
may appear.
- Disabled Mode (where DirectDraw is disabled via the
HydraVision control panel). In this case, all operations
will work but DirectDraw will not be used. This will
result in lower performance.
Note that programs which force video to the center of the screen
(and thus onto the split) such as WinBench96 Video Tests are NOT
compatible with HydraVision DirectDraw when DirectDraw acceleration
is turned on due to the limitations described above.
DirectDraw, by its architecture, is incompatible with graphics
devices that use more than one frame buffer (such as Appian does
for dual monitor operation). DirectDraw assumes that the screen
is fully contained in one frame buffer and will access the frame
buffer directly, bypassing Appian's driver. When this occurs, the
DirectDraw operation can fail.
4) How to UNINSTALL the HydraVision drivers
================================================================
To uninstall the HydraVision drivers under Win95/WinNT 4.0, use
the Add/Remove programs control panel utility. To uninstall the
HydraVision WinNT 3.51 drivers, remove the Appian HydraVision icon
from your startup group.
5) Machine Compatibility
================================================================
Some machines do not actually power down when they restart after
installing the HydraVision drivers. This can cause the driver to
fail. It is recommended that you "Shut Down" the machine after
installing the drivers and then press ctrl-alt-del to restart rather
than use the restart option (reply NO to "Restart Computer?" message
box).
6) WinNT 3.51 notes and bugs - IMPORTANT
================================================================
!! IMPORTANT!! When installing the NT driver, after rebooting
NT will inform you that display settings have changed and will
bring up the NT Display Control panel. Do not click Cancel!
Click OK and use the HydraVision Control panel from then on to
make display setting changes. If you do not do this, subsequent
boots into NT will cause a Dr. Watson divide by 0 error!
7) WinNT 4.0 notes and bugs
================================================================
OpenGL is accelerated on the first, or defualt monitor only.
Certain OpenGL modes incorrectly assume that bitmaps are cached
on the graphics board if DirectDraw is enabled. This is a false
assumption and can lead to drawing errors. If OpenGL programs
appear to be drawing incorrectly, try disabling DirectDraw
acceleration on the Multi-Monitor tab page.
On the Appian Multi-Monitor tab page, a checkbox is avaialble
to enable individual monitor refresh rates. When this option
is selected, the refresh rate displayed on the Settings
tab page may not be accurate. This is because Windows assumes
it is only addressing a single monitor and cannot account for
two or more independent refresh rate settings.
8) Win95 notes and bugs
================================================================
When DirectDraw is enabled, dragging a paused video window will
leave the video window colors corrupted. Starting the video again
will fix the problem. Please refer also to item (2) in this readme.
While Appian supports DirectX 3.0, it is not included on this
distribution disk. Please visit the Microsoft web site to download
DirectX 3.0 files.
Some games (and the Microsoft DirectX 3.0 installer) will attempt
to overwrite and replace the Jeronimo driver files. If this occurs,
please re-install the Jeronimo driver after installing the DirectX
application.
Always run the driver in full acceleration mode. The driver will
not function correctly in any other mode.
9) HydraVision desktop manager tips and notes
================================================================
The desktop manager follows a few rules of operation.
a) Certain applications use windows instead of dialog
boxes to communicate with the user (an example is
MicroStation 95 which uses windows for file open,
save, etc.). In this case HydraVision will not relocate
the window since only dialog boxes are relocated.
b) Single Monitor Windows is a very complex control
which basically attempts to thwart the application's
control over its own window. Some applications
will not allow this control initially and will start
across a monitor split. Clicking on the application's
title bar will cause it to be relocated on a single
monitor.
c) In some cases, desktop management of certain
application windows or dialog boxes causes problems.
If the application expects to see its dialog box or
window on a particular area of the screen and the
window is not there, errors can occur ranging from
mild to severe. Appian purposely does not control
certain dialog boxes known to have this problem.
If, however, you experience a problem running an
application when HydraVision is loaded (the desktop
manager), please try unloading HydraVision and
running the application again. If the cause of the
problem was HydraVision, please let Appian know as
soon as possible (contact information is below).
d) Some applications use child windows for dialog boxes.
These child windows are not relocated by the desktop
manager because (1) they are bound inside their parent
window and (2) HydraVision by definition does not relocate
windows. Some applications which do this (but not all) are:
Adobe Pagemaker 6 - Spell and Find dialogs
Corel Draw 6 - all dialogs under NT (W95 is fine)
Word 7.0 - Spell dialog
Excel 5.0 - Help dialog (actually a window)
Microstation95 - all dialogs
Office97 - paperclip help
The Appian Desktop Manager controls windows and dialog boxes
by examining and modifying system messages which create,
move and destroy dialog boxes and windows. There are hundreds
of ways that programmers can create dialogs. With all of these
variables, the desktop manager is not perfect and can either
miss or incorrectly move a dialog box or a window. In either
case, we would like to know about it so that we can add the
offending application to our test suite in order to correct the
problem. If you have a desktop manager problem, please e-mail
the offending application's name to techsupport@appiangraphics.com.
10) Win95 installation notes
================================================================
The device manager for Win95 automatically detects changes
to the system and offers to install or search for new hardware for
you. This plug-n-play capability, while a worthwhile effort,
does not always work. The bottom line is that Win95 attempts to
hide you from complexity by making assumptions in the installation
of new hardware. This can cause the installation failure of
your display board(s). The "safer" way to install is to prevent
Win95 from making any assumptions about your hardware.
Appian recommends the following general procedure for Win95
installation.
a) If at any point in the installation Win95 asks you to
start the Hardware Wizard or to Search for new Hardware,
select Cancel.
b) The first time that Win95 detects new hardware and asks you
for a driver, select "Have Disk..." and insert the Jeronimo
disk to install the driver.
c) Any subsequent Win95 new hardware detections should be
canceled (click the cancel button).
d) After booting into Win95, bring up the Display Control
Panel. If Win95 asks to start the Hardware Wizard, click
Cancel.
e) Once you are in the Display Control Panel, click the
Settings tab to bring up the settings page. Click the Change
Display Type button.
f) Verify that the Jeronimo driver is listed under the
Adapter type box. If it is not, click the Change button and
follow the instructions to change your driver.
g) At this point you may close the Display Control Panel and
shutdown the machine (DO NOT RESTART WHEN WINDOWS ASKS YOU).
You have now installed the card and driver correctly.
Subsequent boots will use the Appian driver.
11) Using HydraVision SW with more than one J2
================================================================
HydraVision software will automatically recognize and use more
than one Jeronimo board if it is detected in the system. All
additional Jeronimo boards must, however, be configured for
secondary channel operation. The procedure for this is described
in the Jeronimo User's Guide.
When using multiple Jeronimo boards, Appian recommends installing
each board separately; that is, complete the hardware installation
as described in the Jeronimo User's Guide for a single board, boot
up, load the HyrdraVision drivers, and verify that the system is
operating properly. At this point, when you install additional boards
in the system, HydraVision will automatically detect and use the
additional channels. Monitors can then be enabled through the
Appian Multi-Monitor tab in the Display Properties Control Panel.
WARNING - Do not use more than one J2N in one system. This can
cause bus loading problems and lead to the crash of your system.
Use the J2 bridge product instead of the J2N bridgeless board when
you are installing more than one J2 in a system.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
