5.5 Power Loss Control

The cBC has full control of the power-up of the module and therefore can be used to specify the behaviour of the system after a AC power loss

condition. Supported modes are “Always On”, “Remain Off” and “Last State”.

5.6 Embedded BIOS

The conga-TCA is equipped with congatec Embedded BIOS, which is based on American Megatrends Inc. Aptio UEFI rmware. These are the

most important embedded PC features:

5.6.1 CMOS Backup in Non Volatile Memory

A copy of the CMOS memory (SRAM) is stored in the BIOS ash device. This prevents the system from not booting up with the correct system

conguration if the backup battery (RTC battery) has failed. Additionally, it provides the ability to create systems that do not require a CMOS

backup battery.

5.6.2 OEM CMOS Default Settings and OEM BIOS Logo

This feature allows system designers to create and store their own CMOS default conguration and BIOS logo (splash screen) within the BIOS

ash device. Customized BIOS development by congatec for these changes is no longer necessary because customers can easily do these

changes by themselves using the congatec system utility CGUITL.

5.6.3 OEM BIOS Code

With the congatec embedded BIOS it is even possible for system designers to add their own code to the BIOS POST process. Except for

custom specic code, this feature can also be used to support Win XP SLP installation, Window 7 SLIC table, verb tables for HDA codecs, rare

graphic modes and Super I/O controllers.

For more information about customizing the congatec embedded BIOS refer to the congatec System Utility user’s guide, which is called

CGUTLm1x.pdf and can be found on the congatec AG website at www.congatec.com or contact congatec technical support.
