24.9 Kontron BIOS Extensions
Besides the Phoenix System BIOS, the EPIC/PM comes with a few BIOS extensions that support special
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 (JRC)
®
Onboard LAN RPL ROM
All enabled BIOS extensions require shadow RAM. They will be loaded into the same 32K 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.
24.9.1 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 and JIDA 32-bit standard.
The JIDA 16-bit standard is a software interrupt 15hex driven programmers 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 at the Kontron Web site. The
three question marks represent the revision number of the file. You also can contact technical support
for this file.
