First Time Updating A Motherboard

To update the asus sabertooth 990fx r2.0 am3+, do i just download the bios update and that updates the Lan, usb, sata, audio, chipset, etc...or do i have to update each one of those seperately? Also when theres only one update availble, is that the version the motherboard is running or is there really another update? Would appreciate some feedback as i have never updated a motherboard before thanks.


Those are the drivers, not the BIOS. There is only one BIOS homie, and you update it from within the BIOS with ASUS ez flash tool.
