Is any BIOS update for M81 7517 and M81 7517 B2U for Meltdown and Spectre

Hi, On the list of BIOS update for Meltdown and Spectre, I can't find out the status of Lenovo M81 7517 and Lenovo M81 7517 B2U. Does it mean there is no impact for those 2 desktop?

Thanks

This model was discontinued around 2012. I think it's more likely that it is vulnerable but that no update will ever be released.
