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 veried. Once veried the F10 Save and Exit function continues to perform some minor processing tasks and nally 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.
Security Features5.4
The conga-B915 can be equipped optionally with a “Trusted Platform Module“ (TPM 1.2). This TPM 1.2 includes coprocessors to calculate
efcient 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 benet also with improved authentication, integrity and condence levels.
Suspend to Ram5.5
The Suspend to RAM feature is available on the conga-B915.
congatec Battery Management Interface5.6
In order to facilitate the development of battery powered mobile systems based on embedded modules, congatec AG has dened 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 Specication 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 modications to the system BIOS.
The conga-B915 BIOS fully supports this interface. For more information about this subject visit the congatec website and view the following
