These boards should already be supported by the following BIOS check. As
the DMI_BOARD_NAME was changing, it was Kontron's recommendation to use
the FRI2 prefix in the DMI_BIOS_VERSION.

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:
