Additional BIOS Features

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 identified as B915R1xx, where B915 is the congatec internal project name, R is the identifier for a BIOS ROM file, 1 is the
so called feature number and xx is the major and minor revision number.

Updating the BIOS

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.
For more information about "Updating the BIOS" refer to the user's guide for the congatec System Utility, which is called CGUTLm1x.pdf and
can be found on the congatec AG website at www.congatec.com.
10.2

BIOS Recovery

The "BIOS recovery" scenario is recommended for situations when the normal flash 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 flash 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.

BIOS Recovery via Storage Devices

In order to make a BIOS recovery from a floppy disk, CD-ROM (ISO9660) or USB floppy the BIOS file must be copied into the root directory of
the storage device and renamed AMIBOOT.ROM.
For more information about "BIOS Recovery via Storage Devices" refer to application note AN6_BIOS_Recovery.pdf, which can be found on
the congatec AG website at www.congatec.com.
