The biostar should work without a bios update, since it doesn't list any individual bios file requirements for specific cpus. The asus board has two or three possible bios files; manufacturer's don't mark the bios file on the board since the file may change during the manufacturing lifespan of the motherboard. Or, I can sell you my sempron 130 am3 cpu to flash the bios for only $17 shipped. My heat ratings are in anandtech.
k ill keep that in mind if i need a bios update *first time building so going overboard on making sure it will work
