BIOS update to Asus motherboard?

I am building a new pc, and I purchased an ASUS M4A88TD-M/USB3 MB a couple of weeks ago...I suspect that the BIOS is of around April - 2010...(302)....I will save the current BIOS to a Flash Drive, before updating current BIOS, but my question is....there are a lot of newer versions, with the latest being 901....If I download the latest version, does it encompass all the other version updates prior ? I intend to use Windows 7 Ultimate 64 bit....Thanks in advance....
