The programming tool BGT-AMI BIOS Guard Firmware Update Tool is distributed in the following versions:

  • BgtEfi.efi EFI Shell 32-bit programming utility

  • BgtEfix64.efi EFI Shell 64-bit programming utility

  • BgtWin.exe Windows 32-bit BIOS programmer

  • BgtWinx64.exe Windows 64-bit BIOS programmer

Reprogramming the board's BIOS is a critical operation.
DO NOT reset or turn off the system or remove AC power while BIOS update operation is in progress, otherwise this may lead to a not working board.

The first reboot after reprogramming may be slower due to some operations, such as flash re-initialization or embedded controller reprogramming. For this reason it is necessary to wait for the complete boot with the new BIOS before considering the operation completed.

BGT is a very powerful tool which allows a wide range of operations in addition to BIOS reprogramming and most of them could not be supported by the platform.
SECO is not responsible for any change made to the original BIOS with an improper and undocumented use of this tool.
Please, be aware that any operation rather than reprogramming BIOS as documented in this manual may lead to a not working board.

Where can I find BGT utilities?

Latest version of BGT utilities and BIOS update script are available on each product's pages under BIOS Tools section. For more information and instructions you can rely on the Readme files contained within the package.

EFI Shell utility

Copy the updater tool and the BIOS binary inside the USB drive.

Then, turn on the system and enter in the Aptio Setup Utility pressing the [ESC] key.

Under Advanced>PCH-FW Configuration>Firmware Update Configuration menu enable Me FW Image Re-Flash option. Save this configuration by pressing F4.

Save this configuration.

From the Device mapping table identify the filesystem of the USB drive fs* (marked as a Removable HardDisk) and enter there. Move to the folder where BGT utility and the binary file are located and launch the command:

update.nsh BIOSbinary.XXX

where BIOSbinary.XXX is the name of the BIOS you would like to flash.

Windows utility

Copy the updater tool and the BIOS binary file in a folder of the Windows Disk.

Run the cmd shell with Administrator privileges, then move to the folder where BGT utility and the firmware file are placed. From inside here, to update your BIOS execute the command:

update.bat BIOSbinary.XXX

where BIOSbinary.XXX is the name of the BIOS you want to flash.
