I'm thinking about updating my BIOS, but I have a question of what I need to install to upgrade. I have the following choices for my x58 Sabertooth motherboard. I'm currently at Version 0802, do I need to install 0902 and up or can I just install the latest one and assume the other updates are included.
Update to the latest version. It will include all of the fixes from previous versions.
Also, you don't want to upgrade the BIOS any more often than necessary. Even though updating the BIOS is fairly safe, a failed BIOS update is usually catastophic because it can make your computer unable to boot.
