    Z690 dual bios and raptor lake

    Hi,
    I have a Z690 extreme with dual bios.

    I bought the motherboard with a 12900K but before upgrading to raptor lake I upgraded both bioses to the latest 2103 bios.

    Unfortunantly I upgraded to the latest ME firmware only one bios not the other.

    Now I have two bios to the latest version 2103 but only one have the latest ME firmware.

    I read somewhere that in order to support raptor lake both bioses should run the latest me firmware.

    Is this true?

    Will I crash my mobo if I switch to the second biso now that I have raptor but I haven't upgraded the latest ME firmware on the second bios?

    Within my knowledge or you may correct me if I was wrong. I dont think the 2nd bios come into picture. The dual bios I thought supposed to do with fail safe?

    Hello,

    If wanting to utilise the secondary BIOS you will need to upgrade the ME driver and firmware.

    Secondary bios is updated, but how can I update the ME bios now?
    As far as I know usb flashback works only with bios, how can I update the me firmware?

    Thanks

    Thanks
    use the tool in the stickied Raptorlake resource thread in this section. The firmware update can be done from DOS prompt or from within the OS
