Appendix C – BIOS Settings
This section shows and describes the settings available in the BIOS. The content for this section comes
from the manufacturer of the SMARC module.
BIOS Operation
The BIOS (Basic Input and Output System) or UEFI (Unified Extensible Firmware Interface) records
hardware parameters of the system in the CMOS on the Computer-on-Module. It's major functions
include execution of the POST(Power-On-SelfTest) during system start-up, saving system parameters
and loading the operating system. The BIOS includes a BIOS Setup program that allows to modify
system configuration settings. The module is equipped with Phoenix SecureCore, which is located in an
onboard SPI serial flash memory.

BIOS Update
Kontron provides continuous BIOS updates for Computer-on-Modules. The updates are provided for
download on http://emdcustomersection.kontron.com with detailed change descriptions within the
according Product Change Notification (PCN). Please register for EMD Customer Section to get access

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
