I’m on the updated bios now for my board. Bios 0702. Everything seems to work after installing aura version...71. Here is the flashback method:

https://event.asus.com/2012/mb/USB_BIOS_Flashback_GUIDE/I usually shutdown the machine and pull the power cord, press the start button to drain any juice for a few seconds, then clear the CMOS.
Then plug in the cord and the flash drive as above. After it’s finished, I usually remove the flash drive and power cord again and drain any electricity again and clear the CMOS once more to ensure nothing is leftover from the prior bios. Then boot the machine.
