Current Information
===========================
General information:
To use a miroCRYSTAL/miroMAGIC/miroRAINBOW graphics board
the 02E8h address must not be used. This address is used
by COM3, COM4, and gameport expansions, and by some network
boards. In addition, you have to deactivate the VGA on your
motherboard (if there is a VGA).
If the computer does not boot correctly (spec. with an
EISA graphics board and an Adaptec EISA busmaster SCSI
controller 1742) or if the monitor select program does
not detect the installed graphics board, these are computer-
specific problems. To solve these problems, activate ROM
shadowing for the Video BIOS, using the motherboard BIOS
setup or the corresponding Memory Manager option. For
MS DOS 6.0 change the CONFIG.SYS file in the following way:
DEVICE=C:\DOS\EMM386.EXE ... ROM=C000-C800 ...
Please also refer to your computer's manual or to the
MS DOS 6.0 manual.
For all multiscreen and miroTWINFACE configurations ROM
shadowing HAS to be activated for the Video BIOS.
In a multiscreen or miroTWINFACE configuration with a high
resolution VESA local bus (VLB) graphics board and another ISA
or EISA graphics board, the VLB board has to be configured as
first board by setting the jumper. This is not true for a
multiscreen or miroTWINFACE configuration with a miroVGA or a
miroCRYSTAL 8S/ISA.
In a multiscreen or miroTWINFACE configuration the warm start
with the key combination <CTRL> <ALT> <DEL> may not work. In
this case use the reset key (cold start).
Information on the installation:
If you have problems to install from diskette you can also
copy them into a directory on your hard disk.Then, assign a
drive letter to this directory with the SUBST command. Please
refer to the MS DOS manual.
When copying the disks, you have to keep the following order:
first miroWIN Disk 2 and then miroWIN Disk 1
When using a miroCRYSTAL 8S you should consider whether you
prefer an extremely high vertical scan frequency or a high
processing speed. As a compromise, select a 64 kHz monitor.
The resolution of 1024 x 768 pixels with 256 colors is then
realized with 75 Hz. This is due to the fact that the
miroCRYSTAL 8S is equipped with DRAMs.
If you installed a Windows network version, there may occur
problems resulting from the configuration. The miro software
has to be installed at the work place. The installation program
has to be able to copy drivers, applications, and configuration
files to the local Windows directory of the computer at the
work place. In addition, it is neccesary that the local files
SYSTEM.INI, WIN.INI, CONTROL.INI and MWINTOOL.GRP can be
created/overwritten. With the help of the monitor-select-
program each work place is adapted to its individual equipment
by entering specific data in the OCTO.MON and the three *.INI
files mentioned above.
If you exchange your old graphics board by a miroCRYSTAL /
miroMAGIC / miroRAINBOW graphics board or if you exchange
one miro board by the other, you should reconfigure Windows
for VGA. In doing so, you avoid that a wrong driver runs on
your new graphics board when starting Windows and that your
system crashes. Install the driver for the new board in the
VGA mode.
If the call for the OCTOINI program is still in your
AUTOEXEC.BAT from a previous installation, you may
delete this call.
Installation under Norton Desktop:
If you use the Norton Desktop instead of the Microsoft
Program Manager, the miroWINTOOLS group (MWINTOOL.GRP)
which the installation program generates may not be
integrated in the Norton Desktop. To avoid this, start
the Program Manager (PROGMAN.EXE) as a symbol before
starting the installation program or integrate this
group manually in the Norton "Quick Access" group after
the installation. To do so, open the drive window containing
the Windows directory and the "Quick Access" window
and drag the MWINTOOL.GRP file from the drive directory
window to the "Quick Access" window. Also refer to your
Norton desktop manual.
Information on Windows:
At the 640 x 480 resolution do not select the option
"TV overscan" with miroSUPERSCREEN.
If the icons in one of your program groups are black (or you
get an error message concerning this), there are too many icons
in this group. Split this group up into smaller ones. This is
due to Windows and occurs with 65k/16.7 mill color drivers.
If key commands are not accepted after switching to the MS-DOS
prompt, press the <ALT> key. Then, Windows checks the state of
this key and the following key commands will be accepted.
In some cases lines remain on the desktop. To avoid this, enter
VXPBLT=1 in the SYSTEM.INI file under [928.drv].
In the SYSTEM.INI file in the [386Enh] section, you can add
EMMEXclude=A000-FFFF. Then, the whole adapter address range is
excluded from the scanning of free memory blocks.
miroSCOPE has to be closed before calling the MS DOS prompt.
If you don't do so, you can not switch from the full-screen
to the windowed mode by entering <ALT>+<RETURN>.
