@w8p @Eduar Sorry, that bios is from user bjornier which should not be used (partly my fault for not informing), anyways here is the bios that is modded from stock bios for GA-970A-DS3P FX (rev. 2.1).

to kick dual bios flashback, turn off pc, press and hold power button and reset button at once for 11 seconds and release it, then turn it on, so that the bios backup will attempt to flash its own bios. you guys could recover from the password, or the otherway is shorting pin 1 and 6 on your bios chip (please refer to your bios chip model and know the polarity).
