Bios Extension
Besides the PHOENIX System BIOS, the ePanel PM comes with a few BIOS extensions that support special
features. 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.
9.8.9.1.
JIDA BIOS Extension
The JUMPtec Intelligent Device Architecture (JIDA) interface is integrated into the BIOS of the ePanel
PM board. 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 board 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 Website.
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 Website.
9.8.9.2.
Remote Control Client Extension
You can remotely control the ePanel PM using software available from Kontron (JRC-1, Part Number
960470000-00-0). 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. With the JRC client loaded into the first
detected free memory location between C0000h and DFFFFh, 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 Website.
