When I enter the lenovo serial number, it directs me to a bios file that is incompatible with the haswell motherboard, on a bios site there is O00KT20AUS.BIN this bios

Unfortunately, the label has been removed, all the information is in the bios, only the serial in the bios is written, the machine model appears, there is an explanation in the link
