10 Additional BIOS Features
The conga-X945/XA945 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
X945R1xx (X270R1xx.rom for conga-XA945 variants), where X945 (X270 for
conga-XA945 variants) 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.
10.1 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.
10.2.1 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
