Hello Carrrot,
Thank you for posting on the Intel® communities.
As previously stated, if your system has a Dell-manufactured motherboard instead of one manufactured by Intel the BIOS and all updates related to that component should be provided by Dell, if this is the case, please contact them directly. Feel free to use the link below.
