No, that answer that i wrote is backup bios since your mobo has it.
Method 3
Only use this if nothing else works.
Short out pins 1 and 6 on the main BIOS chip by attaching a jumper to both the pins (pin #1 should be marked with a red dot or whatever)
Tell a friend to press the power on button while you do this because right now you are holding the jumper on the pins
Remove the jumper you're holding between pins 1 and 6 as soon as you hear a beep.
Backup BIOS should boot now.
Do this last!!!!!!!!!
If the mobo boots and you can launch dos, you could reflash bios via dos,
Here 's guide,

Bear in mind that you could actually totally brick bios.
You download your bios per usual on official site of the mobo, dont use beta bios.
Extract it, make bootable dos usb, thrn transfer your files onto root of usb.
Then disconnect every hdd from mobo, and if you can select to boot off the usb,
Command lines are in video.
