Software Installation
The software installation refers to the installation of corresponding display
drivers; the installation of the touch screen comprises the allocation of re-
sources for the COM interfaces, too. For this, corresponding diskettes are
available.
The installation of display drivers is normally done after a VGA card is re-
placed with the TFT controller. As these normally need different drivers, it
is highly recommended to set the standard VGA mode (resolution 640 x
480 pixel, 16 colours) before installing the controller.
At any rate you should check, whether the file CON-
FIG.SYS contains an entry for a store manager (like e.g.
EMM386.EXE). This entry must take into account the ne-
cessary cluster of 40 KB (segment address C000-C9FF)
for the BIOS of the TFT controller. A possible entry would
be:
DEVICE= C:\WINDOWS\EMM386.EXE X=C000-C9FF NOEMS
This may be important for MS-DOS, Windows 3.x , Windows 95 or
Windows 98. If you don´t pay attention to it, the system may crash
while starting.
When installing the touch screen software and resource allocation
(I/O address; interrupt) for the COM interfaces, mind the following:
During the installation there may be conflicts concerning the I/O addresses
and the interrupt. So inform yourself of the resources already allocated
and read the instructions in the files, e.g. readme file, of the installation dis-
kettes very carefully. Then you can allocate the resources and set the cor-
responding jumper configuration on the COM board.
The BA71/BA72 is supported by the operating systems MS DOS;
Windows 95/98 and Windows NT. The hardware interfaces and the firmwa-
re interfaces of the display are open. Now it is possible to develop drivers,
e.g. for other operating systems, by software companies.
