    Hi there,
    got an Intel NUC i5 System last week.
    Bought as faulty....no boot device selectable.
    So i managed to get into the UEFI Bios without bios battery, but im unable to update the old 0026 uefi to actual 0040, regardless of which Option i try.
    Update via F7, Power Button, Windows and so on.
    I can select an update ".BIO" file, than it says "start to update...". NUC reboots, FAN spins, Screen stays black, or the NUC just turns off....thats all.
    I then unsoldered the MX25L6406 Flash and made a dump.

    My plan was to Flash the BIO file, but its size is to big.
    Is it somehow possible to extract the "BIOS" file out of the BIO, so i can Flash the chip with my programmer?
    edit: im unable to post the link for the dump. pm me, if you Need it.

    Thanks for your help
