24.10 Special BIOS Hints

24.10.1

Display Configuration

The setting 'PnP/PCI Configurations
detected or not. In case a ISA slot is selected for example, there will be no fallback to the onboard control-
ler, if no ISA VGA card is detected. So the memory range A0000h to BFFFFh may be used for a different
purpose.

24.11 Kontron BIOS Extensions

Besides the Award System BIOS, the MOPSlcdLX comes with a few BIOS extensions that support special fea-
tures. All extensions are located in the onboard Flash. Some extensions are permanently available; some
are loaded if required during boot-up.
Supported features include:
JIDA standard
®
Remote Control feature (JRC)
®
Onboard LAN PXE ROM
®
All enabled BIOS extensions require shadow RAM. 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.
24.11.1

JIDA BIOS Extension

The JUMPtec Intelligent Device Architecture (JIDA) interface is integrated into the BIOS of the MOPSlcdLX
module. This interface enables hardware-independent access to features that cannot be accessed via
standard APIs. Functions such as watchdog timer, brightness of LCD backlight and user bytes in the EEPROM
can be configured with ease by taking advantage of this standard MOPS PC/104 module feature.
The 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 JIDA 32-bit standard.
The JIDA 16-bit standard is a software interrupt 15h driven interface for programmers 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.
24.11.2

Remote Control Client Extension

You can remotely control the MOPSlcdLX 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,
the system BIOS scans the serial ports for an available JRC connection. If detected, it loads the JRC client
BIOS extension into the memory. The JRC client is always loaded into the memory location DE000h, a 16K
block is shadowed.
