As the DMI_BOARD_NAME was changing, it was Kontron's recommendation to use the FRI2 prefix in the DMI_BIOS_VERSION. > cmp = dmi_get_system_info(DMI_BIOS_VERSION); > if (cmp && strnstr(cmp, "FRI2", 4)) Is this not working for you? If not, what is the DMI_BIOS_VERSION reported by your board? And for clarification, we are talking about this right: http://us.kontron.com/products/systems+and+platforms/m2m/m2m+smart+services+developer+kit.html -- Darren Hart Intel Open Source Technology Center Yocto Project - Linux Kernel
