congatec Embedded BIOS
ACPI Support
Power Management and System Configuration
is supported by the congatec BIOS according to
the ACPI specification.
Multi Stage Watchdog Timer
All congatec modules are equipped with a
multi stage watchdog timer supporting different
events such as NMI, hardware reset or power
button. It can either assert a single event and/
or any combination of these events. Triggering
can happen by software and/or external OEM
hardware.
congatec Board Controller
An onboard µc fully isolates some of the
embedded features such as system monitoring
or the I²C bus from the x86 core architecture,
which results in higher embedded feature
performance and more reliability.
Fast Mode I²C Bus
The I²C Bus is a low speed bus interface often
used for sensors, converters or data storage in
embedded applications. All congatec modules
offer a 400 kHz multi-master I²C Bus that provides
maximum I²C bandwidth.
BIOS Setup Data Backup
The BIOS CMOS settings are held in flash memory
to allow battery-less applications.
Customer specific CMOS Defaults
The congatec embedded BIOS allows the
customer to store their own defaults in flash
memory. This helps reduce the need for
customized BIOS versions.
Manufacturing Data Storage
The congatec board controller provides a
rich data set of manufacturing and board
information: Serial Number, Article Number,
EAN Code, Manufacturing and Repair Date,
System Statistics and more. The BIOS also keeps
track of dynamically changing running time and
boot count data. All this data is accessible by a
uniform API.
User Data Storage Area
congatec modules provide 32 Bytes of non-
volatile storage in the EEPROM and a 64 kByte
block in the BIOS flash memory.
Customer Logo
The BIOS can display a custom logo instead of
the traditional diagnostic output during POST. With
the congatec embedded BIOS customers can
now integrate an OEM logo into the standard
BIOS by themselves.
32 Bit Uniform OS API
The congatec embedded BIOS Features are
accessible through a uniform 32 Bit API.
Hardware Monitoring
The congatec BIOS already has the routines to
monitor critical components implemented. Fans,
operating voltages and several temperature
sensors can be monitored without incurring
additional development costs.
Flexible BIOS Expansion
Customer specific code can be executed while
booting the system. During power on self test
(POST) the congatec BIOS can give control to
customer specific code. This gives customers
more flexibility to initialize special hardware
extensions.
congatec System Utility
All Embedded BIOS features are accessible
through the use of a congatec Windows tool.
This includes all manufacturing and statistical
information; e.g. serial number, running hours,
boot counter etc. BIOS default settings, bootlogo
and flat panel configurations can easily be
programmed using this flexible and powerful tool.
Board Support Packages
congatec offers advanced BSPs, which include
both the latest tested drivers from silicon vendors
and the congatec specific drivers for accessing
all of our additional embedded BIOS and
module features.
Embedded computer users usually require more than the standard functionality of an office computer. We at
congatec have taken these requirements into account when designing our BIOS functionality. By drawing on the
wealth of information that has been gathered as a result of many man-power years of combined experience in
BIOS development, we have implemented the special requirements of an embedded BIOS into the congatec BIOS.
