Kontron BIOS Extensions
Besides the Phoenix System BIOS, the
cool
MONSTER/S
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
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 will not load.
25.9.1.
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 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.
25.9.2.
LAN RPL ROM
If the onboard LAN RPL ROM is enabled in the system BIOS setup, an optional ROM for the Ethernet
controller loads into memory during boot up. This optional ROM allows you to boot the
cool
MONSTER/S
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 RPL ROM extension is loaded into the first free memory area between CC000hex and E0000hex
and a 32K block of memory is shadowed.
