How to update bios

hello everyone i was hoping if someone can explain to me how to update my bios i have a sabertooth 990fx r2. any help would be greatly appreciated.

For my M5A97 R2.0 is use Asus' AI Suite to update the bios of my mobo. I just go to the drivers & support section for my mobo on Asus' website to download the latest bios file and use it towards AI Suite.

It's been a flawless experience for me so far, and my mobo is continually getting updates this year. They even update list of support ram modules.

Go to the motherboard page on the manufacturer website and look for the bios section. Download the latest. Put it on a USB. Go into bios. Update using file on USB. Profit.
