BIOS Update
Kontron provides continous BIOS updates for Computer-on-Modules. The updates are provided for download on
with detailed change descriptions within the according Product Change
Notification (PCN). Please register for EMD Customer Section to get access to BIOS downloads and PCN service.
Modules with BIOS Region/Setup only inside the flash can be updated with AFU utilities (usually 1-3MB BIOS binary file
size) directly. Modules with Intel® Management Engine, Ethernet, Flash Descriptor and other options additionally to the
BIOS Region (usually 4-16MB BIOS binary file size) requires a different update process with Intel Flash Utility FPT and a
wrapper to backup and restore configurations and the MAC address. Therefore it is strongly recommended to use the batch
file inside the BIOS download package available on EMD Customer Section.
