OEM BIOS Code/Data
With the congatec embedded BIOS it is possible for system designers to add their own code to the BIOS POST process. The congatec
Embedded BIOS first calls the OEM code before handing over control to the OS loader.
Except for custom specific code, this feature can also be used to support verb tables for HDA codecs, PCI/PCIe OpROMs, bootloaders, rare
graphic modes and Super I/O controller initialization.
Note
The OEM BIOS code of the new UEFI based firmware is only called when the CSM (Compatibility Support Module) is enabled in the BIOS
setup menu. Contact congatec technical support for more information on how to add OEM code.
7.2.5
OEM DXE Driver
This feature allows designers to add their own UEFI DXE driver to the congatec embedded BIOS. Contact congatec technical support for more
information on how to add an OEM DXE driver.

congatec Battery Management Interface
To facilitate the development of battery powered mobile systems based on embedded modules, congatec GmbH defined an interface for
the exchange of data between a CPU module (using an ACPI operating system) and a Smart Battery system. A system developed according
to the congatec Battery Management Interface Specification can provide the battery management functions supported by an ACPI capable
operating system (for example, charge state of the battery, information about the battery, alarms/events for certain battery states and so on)
without the need for additional modifications to the system BIOS.
In addtion to the ACPI-Compliant Control Method Battery mentioned above, the latest versions of the conga-TS370 BIOS and board controller
firmware also support LTC1760 battery manager from Linear Technology and a battery only solution (no charger). All three battery solutions are
supported on the I2C bus and the SMBus. This gives the system designer more flexibility when choosing the appropriate battery sub-system.
For more information about the supported Battery Management Interface, contact your local sales representative.
