    BIOS error codes

    So I have motherboard with installed small LED screen, which presents BIOS error codes.

    Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

    Ex after installing sound card, the motherboard startup fails with the code 15.

    Example picture of code is here.
