I recently purchased a sabertooth 990fx r2.o md and a amd fx8350. I know I have to update the bios for to support the cpu. However, I have problems trying to use the flashback button on the mb. My present bios version is 0803. I downloaded the the version 1101 to a fat32 formatted flash drive, renamed to ST990R20.CAP. I then plug the flash drive to the MB, press the flashback button for 3 seconds got a blinking light for about 5 seconds and it turn steady. I on for an half hour, and then turn on my system and I can't boot into windows and uefi indicates that bios version did not change. Can someone tell what the heck I'm doing wrong.
