Version 2.00
miroCRYSTAL VR2000/4000
=======================
Important hint for DC30 and PCTV users:
=======================================
The recent introduction of Microsoft┤s DirectX technology has made it
possible to use the free memory of a graphics board for an overlay by
transferring the video data directly via the PCI bus. In addition,
DirectX introduces many new functions which are especially suited for
computer games.
New technologies, however, may also lead to problems. On some earlier
systems the combination of DirectX-3, the optimized miro drivers, and
the DC30 board may cause trouble.
For this reason, miro has decided to offer two driver concepts:
the optimized ones and drivers which have been especially designed for
Digital Video applications.
For this reason digital Video users (DC20, DC30, PCTV) will find a
special Digital Video driver version in the \Disksets\DVEDRV\ directory
on the installation CD.
In addition to the miroCRYSTAL VR2000/4000 system software,
this CD contains the following components:
Windows 95
----------
1. Microsoft DirectX
2. ActiveMovie 1.0
Windows NT 4.0
--------------
1. DirectDraw compatible Display drivers
Windows NT 3.51
----------------
1. Display driver
CAD drivers
-----------
1. Autocad 10, 11, 12, 13
2. DOS Version 3D-Studio
Windows 3.x
-----------
1. Native S3 driver
2. S3 Refresh
3. S3 VBE 3.x
4. Galileo Configuration Tool
OS/2 Warp
---------
1. Display driver
Important hints on Windows 95:
==============================
miroCRYSTAL VR is a state-of-the-art highly-integrated graphics adapter
which also includes a 3D Engine. To achieve the complete functionality,
however, the "DirectDraw" system extension by Microsoft
is required. Since Windows 95 does not include DirectDraw yet,
you should first install the complete "DirectX" software on your computer.
You can install "DirectX" easily using the "WINDOWS 95 driver" install option
in the SETUP-MANAGER menu of your CD.
After you installed "DirectDraw" via the "DirectX" installation,
you should install the miro graphics drivers which offer high refresh rates
and optimize the graphics output.
Installing the miro graphics drivers and miroWINTOOLS for Windows 95:
=====================================================================
Note: You can install the miro Windows 95 drivers either using the
setup program on the supplied CD or the Display icon contained
in the Control Panel.
These miro Windows 95 drivers are only suited for the
miroCRYSTAL VR2000/4000 boards in the single-screen solution.
The so-called Twinface mode (dual-screen solutions
of two of these graphics boards or combinations of different boards)
are not supported!!!
Important hints on the installation and the re-installation:
============================================================
Note: With early Windows 95 versions, serious problems may occur
with the automatic hardware detection when re-installing Windows95.
You can avoid this Windows 95 problem by disabling the automatic
detection using the "Hardware assistant" and selecting "Standard
graphics board" under "Graphics board" (also see 4.).
In later Windows 95 versions this error has been corrected.
1.) Please do not use the miro Windows 3.x drivers under Windows 95.
If you have done so already or tried to do so, make sure that all
old miro Windows 3.x drivers and entries will be removed from the
SYSTEM.INI file.
2.) If you use a miro monitor or a multifrequency monitor, we recommend to
use the Miromon.inf file contained on this installation CD. Using
Miromon.inf guarantees that the special parameters suited for your
monitor are used. In the "Display Properties" dialog, select "Change
configuration".
By clicking "Change" in the "Monitor" field, you go to the monitor model
selection. By clicking the "Have disk" and the "Browse" buttons
you go to a file selection window. Select the installation
CD under "Drives" to go to the miroCRYSTAL VR installation directory.
In this way, the mirodisp.inf and miromon.inf files are automatically
selected. Click "OK" to go to the miroMONITOR selection list.
Select the monitor you use.
Note: Please do not try to "soup up" your monitor by selecting frequencies
which exceed the monitor┤s frequencies. In this way, you will
definitely damage your monitor. These cases are not covered by the
warranty!
Please make sure that no old OEM*.INF monitor file is located in your
Win95\INF directory. These INF files are ASCII files you
can view using the Notepad. Before removing these files make sure that
you do not delete the wrong files. If you use the miro monitor files
contained on the original Windows 95 CD, we recommend again to use the
monitor files on the installation CD.
3.) For each graphics drivers installation Windows 95 creates a new OEM*.INF
file in the Win95\INF directory. Windows 95, however, does not remove
the old OEM*.INF files. Please make sure that only the current OEM*.INF
files are located in the directory and remove the old files.
In this way, you can avoid all possible problems!
4.) With the currently supplied Windows 95 version, it may happen that after
having installed miroCRYSTAL VR, Windows 95 starts with an error message
(only 16 colors are available). In this case, Windows 95 does not detect
the S3 ViRGE processor. After having installed the miro software this will
not happen again.
If it is not possible, however, to select the resolution and number
of colors, you can use the miro tool kill3d.exe.
This tool resets your computer to its initial state it was in before
the graphics software has been installed. After restarting Windows
you can install the graphics board as described above.
Please only use the kill3d.exe program in exceptional cases. It is no
substitute for the deinstall program contained in the miroCRYSTAL VR
program group.
5.) If you want to update or reinstall the drivers, please remove the old
miro software using the deinstaller program mentioned above.
To remove all system files, first close the miroPINBOARD.
LIMITATIONS
===========
In general, dual-screen solutions (Twinface) with this graphics board
combined with other miro graphics boards or with boards of other manufacturers
are not supported!!!
Video & Your miro graphics adapter offers very high image refresh
Multimedia rates which relieve eye-fatigue during the daily work with
application software. This can, however, lead to problems when
playing back AVI or MPEG files. To solve this problem, the miro
PINBOARD offers you the miroVIDEO button.
This optimizes the image refresh rates for multimedia
applications (miroVIDEO DC10/DC30, miroMEDIA PCTV).
If there are distortions in the overlay image (stripes), use
this button.
Games under Some games for DirectDraw use screen modes which are not
DirectDraw available when the miroVIDEO button is enabled. In case of
problems, simply disable the video optimization.
640x480 If you cannot switch to the TV mode in this resolution,
enable TV Underscan using the miroPINBOARD.
miroSCREEN Do not use this tool with fixed-frequency monitors. You should
ADJUST not select image sizes and positions which deviate too much
from the default settings because otherwise you may damage the
monitor.
You cannot use miroSCREEN ADJUST simultaneously with MPEG or TV
output.
While miroSCREEN ADJUST is running, please avoid switching the
resolution with miroPINBOARD or Windows95.
Under VGA2TV it is not possible to alter the image size using
the miroSCREEN-Adjust tool. You can, however, adapt the image
position to your TV set. Extreme image positions may lead to
distortions.
Please only use miroSCREEN-Adjust in the TV mode when your
image is not centered sufficiently.
DirectX A DirectX application may notify you that the used driver has
not been tested with DirectX. When the program asks you, if you
want to replace the tested driver by a tested one, please
answer NO.
Please check after having installed games under Windows95,
if the miro driver is still active after restarting your
computer.
If not, you may have to reenable or to reinstall the driver.
Xing! Player If you want to output an MPEG movie on a TV compatible device,
first start MPEG on your computer monitor and then switch to
the TV output. Also switch off the hardware acceleration in the
XING-Setup.
Please do not use a virtual TV Screen during playback.
AVI & TV In case you want to output an AVI movie on TV in the full-
screen mode, enable VGA2TV under DOS.
Windows NT 4.0 The current Windows NT 4.0 version does not yet support
Direct3D. This means that programs, especially games using this
interface, are not operational under Windows NT 4.0.
We recommend to use the Microsoft "Service Release I" for
NT 4.0.
VGA2TV When using VGA2TV (see manual) it may happen that the wrong
character set will be selected when switching to the DOS
full-screen mode.
Enter "mode co80" to achieve a correct 80x25.
Hints on Windows 3.x
================
You can also use your graphics adapter under Windows 3.x although
under restricted conditions. Please note the following hints.
1.) Because Windows 3.x is not capable to detect a new graphics adapter,
change to the Windows directory under DOS and call "Setup".
Select "Display" using the arrow up/down keys and select the
"Other" option which requires the disk provided by the device drive vendor.
2.) Now you can easily install the graphics drivers from the disk or the
supplied CD-ROM. If you are using the installation CD, please enter
the complete driver path, e.g. D:\Disksets\win31\.. .
The driver is, however, not called "miroCRYSTAL VR2000/4000"
but ViRGE which is the name of the graphics processor.
3.) After this installation all possible resolutions will be displayed.
These can, however, be changed and adapted anytime.
You should change the resolution under DOS.
4.) Now install "Galileo".
This tool allows you to change the settings.
Higher image refresh rates
===========================
IMPORTANT! Using the "S3refrsh" program requires some caution.
========== In your own interest, please only select image refresh rates
which are compatible with your monitor. Please refer to your
monitor manual for the characteristics.
1.) To achieve higher image refresh rates, use the "S3refsh.exe" program which
is located in the Windows 3.x directory. Copy this program to the hard
disk and start it.
2.) A screen which a list of refresh rates on the left-hand side will appear.
Above you will find all possible resolutions.
The mouse or the keyboard lets you select desired image refresh rates.
3.) After you made all settings, quit the program by clicking the "Exit"
button. If you want to the settings are saved in the "autoexec.bat" file
so that they are available after the system startup.
4.) Restart your system. Windows now works with the desired settings.
OS/2 Warp
=========
1.) Start OS/2 in the VGA mode and open the OS/2 window (task bar).
2.) If you want to install from disk, this disk has to be called "S3 DRV1".
Switch to drive A:\. Use Setup.cmd, to start the installation.
3.) Press the "y" key to confirm. Now all system files will be copied.
Important: The disk must not be write-protected.
4.) Perform a system shutdown and open the "System configuration" folder.
Here you will find the "Display Driver Install" icon. Double-click this
icon, to call a dialog you can use to make monitor settings. Select
"Primary Display".
After confirming, a driver list will appear which includes the new driver
name "S3 Virge [32 Bit] Version 1.00.08". This driver has already been
selected.
5.) The following dialog selects the monitor values. Please confirm the choice
and click "Install". Again, restart the system.
6.) Under System configuration\System the window at the top displays all
resolutions and the window at the bottom displays all possible image
refresh rates.
7.) Another tip: The "Screen" tab has another page you can enable at the bottom
on the right. Here you can view all data of the selected settings.
In addition, a new monitor name has been added: "Custom:Full S3 Chip
Capabilities".
This monitor offers the maximum refresh rates you can select in the first
page of the screen menu.
OTHER LIMITATIONS
=================
miro Computer Products AG always tries to support a wide range of languages.
Because other manufacturers do no share this opinion, the "ActiveMovie" and
"DirectX" is only available in English.
