Additional BIOS Features

The COM 830 uses a /AMIBIOS that is stored in an onboard Flash Rom chip and can be updated using the
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 B945R1xx, where B945 is the 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.

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”.

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.

BIOS Recovery via Serial Port

The Serial Flash method allows for boot block recovery by loading a BIOS image via a serial port (COM1).
This is can be used by many headless embedded systems which rely on a serial port as a debug and utility
console port. This feature is disabled by default.
