19.11.3 LAN RPL ROM
If the onboard LAN RPL ROM is enabled in the system BIOS setup, an optional ROM for the Ethernet
controller loads into memory during boot-up. This optional ROM allows you to boot the T-
MOPSlcdSA over an Ethernet connection. A server with Intel PXE/RPL boot support is required on
the other side of the Ethernet connection. The setup and configuration of the server, including
PXE/RPL support, is not the responsibility of Kontron.
The RPL ROM extension is loaded into the first free memory area between D0000hex and EC000hex.
A 16K block is shadowed.
19.11.4 DOT-Matrix LCD BIOS Extension
The T-MOPSlcdSA can drive an LCD-DOT matrix display on the parallel port. It can support character
LCDs for up to 40 columns and four rows, which are equipped with a Hitachi HD44780 controller or
a compatible one. A BIOS extension of the T-MOPSlcdSA controls the outputs to the display via
software interrupt INT10hex. You only can use this feature with DOS.
If the DOT-matrix LCD interface is set up by using software tool ALCDINIT.EXE, the BIOS extension
that supports this feature loads during boot-up.
The BIOS extension for the DOT-matrix LCD loads into the first free memory area between
D0000hex and EC000hex; a 16K block of memory is shadowed. However, if the system memory
cannot find free memory space because all the memory is already used for add-on peripherals, the
BIOS extension will not load.
Users can download the software tool ALCDINIT.EXE and a related application note from the
Kontron Web site. Programming, detailed configuration, and connectivity information is available
in Application Note DotMatrixPC104_E???.PDF. The three question marks represent the document
revision number. Users can download the application note from the Kontron Web site, or request it
from technical support.
