If you are asking about replacing your processor, you must ask the system/motherboard manufacturer what processors their BIOS supports.
An upgrade processor must be socket, chipset, and BIOS compatible. Only the system/motherboard manufacturer can tell you what their bios supports.
However, all of this is irrelevant since you have a bga socket, which means your processor is soldered to the motherboard.
