Once the BIOS Setup Program has been entered and the settings have been changed,
the user saves the settings and exits the BIOS Setup Program using the F10 key
feature. After the F10 function has been evoked, the CMOS Data is stored in a
dedicated non-volatile CMOS Data Backup area located in the BIOS Flash Memory chip
as well as RTC. The CMOS Data is written to and read back from the CMOS Data
Backup area and verified. Once verified the F10 Save and Exit function continues to
perform some minor processing tasks and finally reaches an automatic reset point,
which instructs the module to reboot. After the Automatic Reset has been triggered the
congatec module can be powered off and if need be removed from the baseboard
without losing the new CMOS settings.
5.4 SDVO
Two SDVO (Serial Digital Video Output) ports are supported via a connector located on
the bottom side of conga-X945/XA945. These ports support the connection of external
transmitters such as DVI, TV-Out, and LVDS. For more information about the pinout of
the connector (X6) see section 7.8 of this document.
5.5 Security Features
The conga-X945/XA945 can be equipped optionally with a “Trusted Platform Module“
(TPM 1.2). This TPM 1.2 includes co-processors to calculate efficient hash and RSA
algorithms with key lengths up to 2,048 bits as well as a real random number generator.
Security sensitive applications like gaming and e-commerce will benefit also with
improved authentication, integrity and confidence levels.
5.6 Suspend to RAM (S3)
The Suspend to RAM feature is available on the conga-X945/XA945.
5.7 congatec Battery Management Interface
In order to facilitate the development of battery powered mobile systems based on
embedded modules, congatec AG has 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 (e.g. charge state of the battery, information about the
battery, alarms/events for certain battery states, ...) without the need for any additional
modifications to the system BIOS.
The conga-X945/XA945 BIOS fully supports this interface. For more information about
this subject visit the congatec website and view the following documents:
