3.) Installation of the drivers
a) Start the "Windows NT setup"-program of the group "main" and
wait a moment.
b) Open the menu "options" und select "Change System Settings".
c) Open the option box for "Displays" of the new window
"Change System Settings".
d) In here scroll until the end and select "Others (Requires a
disk from a hardware manufacturer)".
e) A new window "Insert Disk" appears and you are requested to
insert the installation disk "A:\". If necessary, the default
selection can be overwritten.
f) The window "Select OEM Option" appears and you get a list of
the supported miro boards with their resolutions and frequencies.
Select an appropriate resolution according to your board and monitor
and wait a moment.
g) The window "Change System Settings" appears again, indicating
the selected driver at "Displays". Confirm by using the "Close"
button.
h) If you already installed the drivers in former times you are asked
whether you want to install the former or the new drivers. Confirm
the new installation by using the button "New".
i) A new window "Windows NT Setup" appears and you are requested to
insert the installation disk. Confirm by using the "Continue" button.
j) Now you see the introduction menu of the setup-program. Leave
the program now, e.g. by selecting the menu "Options" and "Exit".
k) Windows NT gives you the information that the new driver will
only be effected after a system reboot.
In case of a board with two drivers available (e.g. 256 and 16.7
million colours) the procedure b) to i) has to be repeated for
the second driver.
If problems of the display driver occur when rebooting the system,
you have the possibility to reselect the former configuration by
using the option "last known good menu". If this doesn`t solve the
problem you have to repair your system by using the Windows-NT-setup-
disk/-CD and the "Emergency Repair Disk". The "Emergency Repair Disk"
should include a configuration with a VGA-driver "640x480, 16 colors"
and your system has to run properly with this driver under all circum-
stances. So you can start trouble-shooting now. In order to repair
your system only select the options "Inspect configuration registry"
and "SYSTEM (System Configuration)".
If you change the graphics board don`t forget to reconfigure your
system on the VGA-driver before. So you get a properly running
system after changing the board and you will be able to install
the drivers for the new board.
The S3-drivers on the Windows NT-Setup-CD don't run together with
miroCRYSTAL 20SD (twin), miroCRYSTAL 20SV (ergo/twin), miroCRYSTAL 40SV
(ergo/twin) and miroMAGIC 20SV/40SV ergo/twin.
4.) Change of resolutions and colour modes
a) Start the "Windows NT setup"-program of the group "main" and
wait a moment.
b) Open the menu "options" und select "Change System Settings".
c) Open the option box for "Displays" of the new window
"Change System Settings".
d) Select the desired resolution from the list of the drivers installed
for your board and your monitor. Miro now inserts the version number
into the description string. Select the desired resolution for your
board and monitor with the highest version number to avoid the
installation of an old old driver or the use of an old installation
script.
e) If the driver is not installed yet a new window "Windows NT Setup"
appears and you will be requested to insert the installation disk.
Confirm by using the "Continue"-button.
f) If the driver has already been installed you will be asked whether
you want to install the current or a new driver. Confirm the use
of the pre-installed driver by using the "Current"-button.
g) Now you see the introduction menu of the setup-program again.
Leave the program now ( e.g. by using the menu "Options" and "Exit").
h) Windows NT gives you the information that the new driver will only
be effected after a system reboot.
5.) Special hints concerning the truecolor driver
The truecolor-driver is created as an accelerated framebufferdriver
in the flatmodel.
As a basic address of the framebuffer the driver presets the
following 32-bit addresses:
- board for VL-bus : FE80.0000 (hex)
- board for PCI-bus : FE80.0000 (hex)
If the boards don't run with these addresses (e.g. as a result of an
incomplete address decoding of your motherboard) the addresses can be
overwritten by an entry into the registry. Repair your system by
applicating the measurements described at 3) together with the VGA-
driver. Start the registry-editor REGEDT32.EXE of the \WINNT\SYSTEM32
directory. Use its help-function for operating. Look for the key
HKEY_LOCAL_MACHINE on Local Machine
\SYSTEM
\CurrentControlSet
\Services
\miroFlatModel
\Device0
Select EDIT and AddValue with your mouse. Insert the ValueName
"FrameBufferBaseAddress" and the DataType "REG_DWORD". In the following
menu-box insert a new address that will shurely work on your computer.
After the confirmaton you will find the new inserted address beside
data e.g. concerning resolution and colour-mode in the right window.
You can delete this value by indicating with the mouse and pressing
the DEL-Key. Take care not to change or delete any other value -
your system would not be able to run after a system-reboot!
One of the following versions of the installation disk will include a
DOS-test-program that enables you to check a miro-board concerning
available addresses.
6.) Association of the drivers with the various boards
- CRYSTAL.SYS and CRYSTAL.DLL : 256 colours driver for
- miroCRYSTAL 20SD (twin)
- miroCRYSTAL 20SV (ergo/twin)
- miroCRYSTAL 40SV (ergo/twin)
- miroMAGIC 20SV/40SV ergo/twin
- FCRYSTAL.SYS and FCRYSTAL.DLL : Highcolor- and Truecolor-driver for
- miroCRYSTAL 20SD (twin)
- miroCRYSTAL 20SV (ergo/twin)
- miroCRYSTAL 40SV (ergo/twin)
- miroMAGIC 20SV/40SV ergo/twin
- S3.SYS and S3.DLL : 256 colours driver for
- miroCRYSTAL 10SD
7.) Delete drivers
Drivers that will no longer be used or that are out of date can be
removed by reconfiguring with the Windows NT setup-program a different
driver (e.g.: VGA Standard 640x480, 16 colors), rebooting the system
and then deleting with the help of the file-manager at \WINNT\SYSTEM32
the display-driver (extension: .DLL) and at \WINNT\SYSTEM32\DRIVERS
the miniport-driver (extension: .SYS). From now on miro adds the
file-time to the version number.
After the installation of drivers with the option "Other..." there
will exist several files OEMVIOx.INF (x=0,1,...) in the directory
\WINNT\SYSTEM32. These are the renamed installation scripts of the
current and the former installation disks. You should delete all of
them except the file with the highest 'x' (the current installation).
If you don't do so, drivers will be listed several times and by
different installation disks and versions.
Moreover the refering key should be deleted in the registry with the
help of the registry-editor REGEDT32 (look at 4.) ). Look for the key
HKEY_LOCAL_MACHINE on Local Machine
\SYSTEM
\CurrentControlSet
\Services
\miro8BPP for the 256 colours driver
\miroFlatModel for the highcolor- / truecolor-driver
\s3 for the driver for 10SD
Select the key in the left window with your mouse and delete it with
the DEL-key. Take care not to change or delete any other key - your
system would not be able to run after a system-reboot!
8.) Supported resolutions and frequencies of the various boards
With this disk-release miro changes the original timings of these
drivers to timings that are approximated to the VESA-standards.
Horizontal and vertical refresh rates are approximated data and
may change according to the technical and market development.
The timings for resolutions of 1408x1024 pixels are not part of
the VESA-standards but are adapted to them by miro.

9.) Special hints for miroCRYSTAL/miroMAGIC 20SV/40SV twin/ergo
and miroCRYSTAL 20SD twin
If you want to install/configure the graphics board
"miroCRYSTAL 40SV ergo/twin" resp. "miroMAGIC 40SV ergo/twin"
please select "miroCRYSTAL 40SV" in the setup-program.
If you want to install/configure the graphics board
"miroCRYSTAL 20SV ergo/twin" resp. "miroMAGIC 20SV ergo/twin"
please select "miroCRYSTAL 20SV" in the setup-program.
If you want to install/configure the graphics board
"miroCRYSTAL 20SD twin" please select "miroCRYSTAL 20SD" in the
setup-program.
This version of drivers do not support the "TWINFACE"
mode of the miroCRYSTAL 20SV/40SV twin. However, the output is
switched to the second HiRes board and -monitor. Despite the
VGA DOS box is displayed in full screen mode on the first monitor.
10.) If problems occur...
In case of problems with the VGA-DOS-box in fullscreen-mode you
should ask your dealer or miro for an update of the BIOS-ROM.
A unsyncroniced image may be caught by switching between the
windowed- and the fullscreen-mode of the VGA-DOS-box.
The VGA-DOS-box as a part of the operating system only supports
the resolutions available for a 'standard VGA', e.g. display
modes 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.
