2.2.) Hardware installation
Install your graphics board as described in the Hardware Manual
supplied with your board. To use miroTWINFACE with two monitors
having different technical data, connect the monitor with the
lower resolution to the daughterboard. Connect the second monitor
to the basic board. If you have two monitors with identical
technical data, you do not have to connect them as described
above. The monitor connected to the daughterboard displays the
boot messages and the fullscreen DOS prompt. Make sure that DIP
switch 2 is not set to ON.
It is assumed that the monitor connected to the daughterboard
is located on the right-hand side of your desktop and the
monitor connected to the basic board on the left-hand side.
This allocation can be redefined as described under 2.4.d).
We recommend this arrangement, however, for monitors with
different technical data, because then the icons for minimized
programs are always located at the bottom on the left-hand
side in the visible screen area.
2.3.) Driver installation
It is required that you have installed Windows NT 4.0 with a
graphics driver for your VGA board.
a) By using the Icon "My Computer", you can start the "Control Panel"
program..
b) Start the "Display-Tool". Switch to the "Settings" section.
c) Please choose the "Change Display Type" button.
d) The "Display Type" window offers an overview of the currently
active Display Driver. Please activate the "Change..."-button.
e) In the "Select Device" offers you an overview of all display
drivers supplied with your Windows NT 4.0 Installation. Please
select the "Have Disk..."-button.
f) In the "Install from Disk" window, please choose the driver and
directory containing your installation software. You can search
your drivers by using the "Browse"-button. Only files with the
filename extension ".inf" are displayed. The file you have to
look for is named "mirotwin.inf".
g) After selecting the proper file, you choose the installed graphics
board from the "Change Display" window. Select your board and
press "OK" or doubleclick the appropriate entry in the list.
h) Select "YES" in the "Third-party Drivers" messagebox.
The driver files are now being copyied to your harddisk.
i) Close the "Display Type" and the "Display Properties" windows and
reboot the computer.
j) After the restart the driver which has just been installed
is active with the lowest resolution (31 kHz VESA monitor:
640 x 480, 256 colours, 60 Hz). Go on with 2.4.) to select a
monitor and with 2.5.) to change the resolution.
If problems occur with the display driver when restarting
the system, you can reselect the VGA driver by using the
"Windows NT Version 4.0 [VGA mode]" option in the boot menu.
If this doesn`t solve the problem use the "last good menu"
option to reselect the old configuration.
If your system uses another display driver, you need the installation
disk to enable the miro driver again.
2.4.) miro Monitor Select - Control Panel extension
a) By using the Icon "My Computer", you can start the "Control Panel"
program..
b) To select the monitors, start the "miro Monitor Select"-Tool.

d) If the boards are not assigned to the correct monitor, you
can change this setting using the "Boot messages on left
monitor" / "Boot messages on right monitor buttons. Select
the monitor on which the boot messages appeared. After
changing the setting, the titles are updated according to
2.4.c). Also, the resolution list may change according to
2.4.f).
e) Select your monitor from the "Monitor" list. If your monitor
is not listed, select the monitor from the "Multi Frequency"
monitors with the frequency which comes close to the frequency
of your monitor.
f) After a short while you see the "Available Resolutions" list
which gives you an overview of all resolutions supported by
your monitor and the horizontal and vertical refresh rates.
Please make sure that you do not select a horizontal scan
frequency which is higher than the horizontal scan frequency
of your monitor.
g) To avoid loading the miroTWINFACE driver, press the "disable
miroTWINFACE" button. If you disabled the "Disable current
driver" button, the driver running before (e.g. miroCRYSTAL
(single-screen) ) or the VGA driver is activated.
h) To confirm your selection, click "OK".
i) In the "Monitor Settings Change" window you can restart your
computer immediately by pressing the "Restart Now" button.
You can also click the "Don't Restart Now" button to get back
to the "Control Panel" program. Restart the system using the
taskbar.
j) After the restart the selected monitors are active. If the
resolutions and refresh rates differ from the settings of
the previous monitor, the system will notify you. Then, the
640 x 480 resolution with 256 colors and 31 kHz / 60 Hz is
enabled for both screens. To change the resolution, proceed
with 2.5.).
k) Instad of proceeding as described under h), you can abort the
tool by pressing the "Cancel" button. In this case, the settings
you made will not be enabled.
PLEASE NOTE:
The "miro Monitor Select" icon is only available in the
"Control Panel" program, if a driver installed from this disk
is currently active.
If you disabled the miroTWINFACE driver under 2.4.g), the
miroMONITOR-Select program for the single-screen operation receives
another button which activates miroTWINFACE. For the single-screen
and the dual-screen operation the monitors have to be configured
individually. There is no synchronisation between both installations.
2.5.) Changing the resolutions
a) By using the Icon "My Computer", you can start the "Control Panel"
program..
b) Start the "Display" tool to select/change the video display.
c) The "List All Modes" button lists the resolutions your
board and your monitor support and the number of colours
and frequencies. Double-click to select a resolution.
PLEASE NOTE:
For miroTWINFACE for Windows NT version 4.0 the horizontal
resolutions are added, the vertical resolution is the
maximum resolution of the basic board. If this resolution
is higher than the maximum vertical resolution of the
daughterboard, the remaining screen area is displayed
virtually, the workspace can be moved by moving the mouse
cursor toward the upper or the lower screen margin. The
selected frequency refers to the monitor connected to the
basic board. Detailed information for both monitors you will
receive from the "miro Monitor Select" program.
d) You can also use the "Desktop area" slider, the
"Color Palette" and the "Refresh Frequency" windows to
select a resolution. Keep in mind that the settings are
interdependent. If you select an invalid setting, the
other options change so that a valid setting is restored.
e) To check the selected resolution in a testscreen, click
the "Test" button and confirm.
- Is the selected resolution/frequency displayed on both
monitors?
- Is the specified resolution the resolution of the visible
screen area?
- Are the arrows in the margins of the testscreen visible?
(In the virtual mode the arrows are not visible on the
monitor connected to the daughterboard.)
- Are the coloured and the hatched areas displayed correctly?
f) After five seconds the testscreen disappears and you see the
workspace again. If the resolution on the testscreen is OK,
confirm the "Testing Mode" window with "Yes".
g) You can restart the computer immediately by clicking "Restart Now"
in the "Display settings change" window. You can also click the
"Don´t Restart Now" button to go back to the "Display type" window.
To close this window click "Close". To close the "Display settings"
window click "OK". Use the Program Manager to restart the system.
h) After the restart the new resolution is active.
i) If you do not like the resolution, click "No" in the "Testing Mode"
window. After another message has appeared, you are back in the
"Display Settings" window. Select another resolution and continue
with e) or close the Display Tool by clicking the "Cancel" button.
The "Font Size" window allows you to select another font size
(see d)). If you have not installed the fonts of the selected
size, you are requested to insert the installation disk under
A:\. Overwrite the default with the drive letter of you CD drive
and enter the path \i386. Insert the Windows NT Version 4.0 CD
in your CD drive so that the required files can be copied to your
hard disk.
2.6.) miro Video Address (Control Panel extension)
To accelerate the image output even more, activate the linear
video addressing function. For this purpose an extension of the
Control Panel is installed during the installation. Open the
Control Panel Program and click the "miro Video Address" icon
to configure the linear video address,
PLEASE NOTE:
Keep in mind that problems may occur with motherboards which
do not decode the addresses completely and in case of address
conflicts with other memory-mapped expansion boards or with
the main memory.
PLEASE NOTE:
For the driver for Windows NT 4.0 and a computer with PCI bus
your system activates this option automatically. If any problems
occur with your motherboard (e.g. older motherboards with PCI
bus and Vesa Local bus), disable this option. All other
adjustments of this tool will be ignored by the driver.
Use the "Linear Video Addressing enabled" and the
"Linear Video Addressing disabled" buttons to switch the
linear video addressing function on/off:
- "Linear Video Addressing enabled" switches this option on.
Then the video memory of the graphics board is unsegmented
and can be accessed by the display driver under the address
specified under "Physical address".
- "Linear Video Addressing disabled" switches this option off
(default setting).
The linear video address is specified under "Physical address".
This address can be overwritten with a hexadecimal value. Make
sure that the new address is aligned with 8 MB (example of
sequence of increasing addresses: 7400.000 - 7480.000 - 7500.0000).
(Default setting: fe00.0000)
Use the arrow buttons beside the display window to increase /
decrease the video address in 8 MB steps.
The "Reset" button enables the default settings.
Confirm your settings by clicking "OK" and close the
"configuration of linear video address". The settings take
effect after the computer has been restarted. If the address
you entered is not aligned correctly, you cannot close the
window using the "OK" button. Correct the setting or click
"Cancel" to abort.
If problems occur with the display driver when restarting
the computer, start the system with another driver as
described under 2.3) and switch the linear video
addressing function off.
PLEASE NOTE:
The "miro Video Address" icon is only available in the "Control Panel"
program, if a driver installed from this disk is currently active.
2.7.) Positioning windows
2.7.1.) miroTWINFACE control - Program for positioning windows
Along with the miroTWINFACE drivers, a program for controlling
the window positions is copied to your hard disk. This program
extends the possibilities for positioning windows the driver
offers. When this program is active, dialog boxes, which
otherwise appear on both screens. appear on the screen where
the mouse cursor is located. When clicking on the Maximize
button, the window is maximized on the screen, where the
mouse cursor is currently located.
For information on how to configure miroTWINFACE control, refer
to 2.7.2.). To close the program, select the "Close" command
in its system menu or log out.
NOTE:
Not all windows can be controlled by miroTWINFACE control. This
phenomenon is inherent in the system and must not be regarded
as a failure. In case of incompatibilities with apllications
you use, you cannot use miroTWINFACE control.
2.7.2.) miroTWINFACE control - Control Panel Extension
This extension is copied together with the "miro Monitor
Select" extension. Open the Control Panel Program and click the
"miroTWINFACE control" icon to configure miroTWINFACE control.
To configure the positioning of maximized windows, select the
"MAXIMIZE alignment" button (default = off).
To configure the positioning of the dialog boxes, click on the
"Dialog alignment" button (default = off).
To confirm, click "OK" and close the "configuration of
miroTWINFACE control". Now, the selected settings are saved and
will be used immediately.
To abort the configuration, click on "Cancel".
NOTE:
In case of incompatibilities with some applications, one or both
options cannot be used or used simultaneously.
3.) Deleting drivers
Delete drivers you do not need anymore by enabling
another driver using the Display Tool of the Control
Panel program and by restarting the sytem afterwards.
Then, use the File Manager to delete the display driver
(extension .DLL) under \WINNT\SYSTEM32 and the
miniport driver (extension .SYS) and the configuration
files (extension .INI) under \WINNT\SYSTEM32\DRIVERS.
4.) In case of problems
In case of problems with the VGA DOS box in the
fullscreen mode ask your dealer or miro for an update
of the BIOS-ROM. In some cases an unsynchronized image
may stabilize by switching between the window and the
fullscreen mode of the VGA DOS box.
The VGA DOS boxs only supports the resolutions
available for a 'standard VGA', e.g. display modes of
up to 320x200 pixels with 256 colors or 640x480 pixels
with 16 colors. If a DOS application tries to use a
higher resolution, the VGA DOS box, or, in the worst
case, the hole system might crash.
5.) Special hint
Please do not try to install drivers or system-relevant
tools which are suited for Microsoft Windows 3.x or
Microsoft Windows 95. Windows NT 4.0 does not support
these drivers or tools. In the worst case, this may
cause a system crash.
6.) Anomalies and Bugs fixed with this release
- Problems with mainboards which do not support switching
off VGA PALETTE SNOOP are fixed
- Design Alert from Microsoft has been incorporated
- Problems with switching to singlescreen after subsequent boots
after installation has been fixed
