Additional BIOS Features10

The conga-B915 uses a congatec/AMIBIOS that is stored in an onboard Flash Rom chip and can be updated using the congatec System Utility,

which is available in a DOS based command line, Win32 command line, Win32 GUI, and Linux version.

The BIOS displays a message during POST and on the main setup screen identifying the BIOS project name and a revision code. The initial

production BIOS is identied as B915R1xx, where B915 is the congatec internal project name, R is the identier for a BIOS ROM le, 1 is the

so called feature number and xx is the major and minor revision number.

Updating the BIOS10.1

BIOS updates are often used by OEMs to correct platform issues discovered after the board has been shipped or when new features are added

to the BIOS.

BIOS Recovery10.2

The “BIOS recovery” scenario is recommended for situations when the normal ash update fails and the user can no longer boot back to an

OS to restore the system. The code that handles BIOS recovery resides in a section of the ash referred to as “boot block”.

For more information about “BIOS Recovery” refer to application note AN6_BIOS_Recovery.pdf, which can be found on the congatec AG

website at www.congatec.com.

the storage device and renamed AMIBOOT.ROM.
