I have a Sabertooth 990FX R2.0. Never really felt the need to update the BIOS and sticking to the old "If it isn't broke, don't fix it" saying. But then I realized I don't know how to update the BIOS even if I wanted to. So figured I'd ask how to go about that.
I find the BIOS update downloads on the ASUS site but it isn't as simple as downloading a file and just updating it is it? I'm not gonna touch it for now just thought I'd ask for future reference if anyone wants to let me know.
From the ASUS page for your motherboard. Select Support -> Drivers and Tools. Choose your operating system. Under the BIOS tab, snag the latest BIOS. If updating via a USB flash drive, under BIOS utilities, grab the "Bios Renamer for USB BIOS Flashback" and follow the directions. Throw the resulting file on a USB flash drive. Restart your computer and enter the BIOS. Find the BIOS update option. Navigate to the file on the USB flash drive (or the file on your hard drive if you're doing it that way). Click through the prompts if there are any. Wait for it to flash that shit. Success.
Alternatively, you should just be able to choose to update the BIOS via the internet in the same area of the BIOS, or through the ASUS utilities in Windows. BIOS updating is easier than it's ever been.
