2.2.) Hardware installation
Install your graphics board as described in the Hardware Manual

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 copied 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.

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 to defaults" 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.) Special Notes for miroCRYSTAL/miroMAGIC 20SV/40SV/44SV/84SV twin
and miroCRYSTAL 20SD/22SD twin
Please note that DIP-switch 2 is NOT switched to the "ON"
position if both monitor outlets are connected to monitors.
For graphics output only the 2nd Board and Monitor is used.
bootmessages and the fullscreen dos box are shown on the
2nd board/monitor.
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 \WINNT40\SYSTEM32 and the
miniport driver (extension .SYS) and the configuration
files (extension .INI) under \WINNT40\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 box 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.
