    Question Prime Z490-A unlabled headers

    Does anyone know exactly what the 2 unlabeled headers are for, maybe an LPC and TMP header?

    The first on is just behind the M2 (WIFI) slot. It's a 2 x 5 with 1 pin missing.

    The second is next to the power button on the board. It's a 2 x 5 with 1 pin missing.

    Neither are mentioned in the manual at all.

    I am sure they are for repair service, what bus or protocol do they use?

    Hi there,
    Sorry for our late confirmation.
    Both of the headers are for service, so that's why they are not labeled.
    One is for installing BIOS and one is for debug.
    Thank you very much.
