Embedded BIOS
The conga-BM67/BS67 is equipped with congatec Embedded BIOS, which is based on American Megatrends Inc. Aptio UEFI firmware. 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 flash device. This prevents the system from not booting up with the correct system
configuration 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 configuration and BIOS logo (splash screen) within the BIOS
flash 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 specific 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.
