Updating asrock p67 extreme4 (not gen3)

[Guide] Manual AMI UEFI BIOS Modding

I was following this guide, but I have a problem.
For this motherboard, they only have an exe file

How can I extract the bios from this?

Thanks

This website has all of the BIOS available for your motherboard, extracted from the exe for USB flashing.

edit: woops nevermind

Thank you!

For anyone else using this old motherboard, this is the 3.21 bios which works great even though it was never officially released. I put the 12.9 intel raid rom and it has the OROM for 6 series motherboards so TRIM works.
Thanks to Fernano and the crew for making it so easy with UBU.

Could you re-upload 3.21 modded BIOS for Asrock Extreme4 B3, pls?
