19.11Kontron BIOS Extensions
Besides the AMIBIOS, the T-MOPSlcdSA comes with a few BIOS extensions that support additional
features. All extensions are located in the onboard Flash EEPROM. Some extensions are
permanently available; some are loaded if required during boot-up. Supported features include:
 JIDA standard
 Remote Control feature (JRC)
 Onboard LAN RPL ROM
 DOT-matrix LCD
All enabled BIOS extensions require shadow RAM. They will be loaded into the same 16K shadowed
memory block, if possible. However, if the system memory cannot find free memory space because
all the memory is already used for add-on peripherals, the BIOS extensions do not load.
19.11.1 JIDA BIOS extension
The JUMPtec Intelligent Device Architecture (JIDA) BIOS extension is not a true extension BIOS. It
is part of the system BIOS and is located in the system BIOS segments after boot-up. It is
permanently available and supports the JIDA 16-bit standard and the JISA 32-bit standard. The
JIDA 16-bit standard is a software interrupt 15hex driven programmer interface and offers lots of
board information functions. For detailed information about programming, refer to the JIDA
specification and a source code example (JIDAI???.ZIP), which you can find on the Kontron Web
site. The three question marks represent the revision number of the file. You also can contact
technical support for this file.
For other operating systems, special drivers (JIDAIA??.ZIP) are available. You can download the zip
file from the Kontron Web site.
19.11.2 Remote Control Client Extension
You can remotely control the T-MOPSlcdSA using software available from Kontron (JRC-1, Part
Number 96047-0000-00-0). This software tool can communicate with the board via one of the
serial ports. During boot-up of the T-MOPSlcdSA , the system BIOS scans the serial ports for an
available JRC connection. If detected, it loads the JRC client BIOS extension into the memory. With
the JRC client loaded into the first detected free memory location between D0000hex and
EC000hex, a 16K block is shadowed.
For more information on the Remote Control usage, refer to the JRC-1 technical manual or
Application Note JRCUsage_E???.PDF, which you can find on the Kontron Web site.
