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
delivered with the system.
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 CONFIG.SYS contains an
entry for a store manager (like e.g. EMM386.EXE). This entry must take
into account the necessary cluster of 40 KB for the "D1" Motherboard (seg-
ment address C000-C9FF) for the BIOS of the TFT controller, resp. 48 KB
(segment address C000-CBFF) for the "D2" Motherboard.
Entry for "D1" Motherboard:
DEVICE= C:\WINDOWS\EMM386.EXE X=C000-C9FF NOEMS
Entry for "D2" Motherboard:
DEVICE= C:\WINDOWS\EMM386.EXE X=C000-CBFF NOEMS
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 interrupts. 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 BA73A is
supported by the operating systems MS DOS; Windows 98, Windows
2000, Windows Me and Windows NT. The hardware interfaces and the
firm-ware interfaces of the display are open. Now it is possible to develop
drivers, e.g. for other operating systems, by software companies.
