BIOS Update

Kontron provides continuous BIOS updates for Computer-on-Modules. The updates are provided for download on
http://emdcustomersection.kontron.com
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.
» Boot the module to DOS/EFI Shell with access to the BIOS image and Firmware Update Utility provided on EMD
Customer Section
» Execute Flash.bat in DOS or Flash.nsh in EFI Shell
