24 Appendix B: BIOS Operation
Kontron User's Guide EPIC/CE 85
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.
For other operating systems, special 32-bit drivers (JIDAIA??.ZIP) are available. You can download the
zip file from the Kontron Web site.
24.9.2 Remote Control Client Extension
You can remotely control the EPIC/CE 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. With the JRC client loaded into the first detected free memory
location between C0000hex and DFFFFhex, 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.
24.9.3 LAN PXE ROM
If the onboard LAN PXE ROM is enabled in the system BIOS setup, a special optional ROM for the Ethernet
controller loads into memory during boot-up. This optional ROM allows you to boot the EPIC/CE over an
Ethernet connection. A server with Intel PXE boot support is required on the other side of the Ethernet
connection. The setup and configuration of the server, including PXE support, is not the responsibility of
Kontron.
The PXE ROM extension is loaded into the first free memory area between C0000hex and DFFFFhex and a
16K block of memory is shadowed.
24.10 Updating or Restoring BIOS Using PhoenixPhlash
PhoenixPhlash allows you to update the BIOS by using a floppy disk without having to install a new ROM
chip. PhoenixPhlash is a utility used to flash a BIOS to the Flash ROM installed on the EPIC/CE.
Use PhoenixPhlash to:
®
Update the current BIOS with a newer version
®
Restore a corrupt BIOS
