How to use BIOS Flashback

  • Sticky post

NOTICE: These instructions apply to both Intel and AMD boards.

  • Most boards include a feature called BIOS Flashback that will allow the BIOS to be updated prior to booting up for the first time.
  • Most can complete BIOS flashback without having a CPU, RAM, or video card installed.
AMD AM4 boards: (B450, X470, B550, X370, X570)
  • Need to have the BIOS updated prior to being able to boot any 5000 Series Ryzen.
AMD AM5 boards: (B650, B650-E, X670, X670-E)
  • Need to have the BIOS updated prior to being able to boot any 7000X3D Series Ryzen.
Intel LGA1700 boards: (B660/Z690/Z790)
  • Need to have the BIOS updated prior to being able to boot 13th or 14th Gen Intel CPU.

If your board does not support BIOS flashback, you will need to have the BIOS flashed with a SPI programmer or a spare older generation CPU temporarily to boot and update.
