My Gigabyte B450 I Aorus Wifi Pro doesn't work since a failed flash 2 days ago.

I am not sure which of these 2 chips is the bios, any way to tell?

Thanks

Thanks, may I ask you how you can determine which one it is?

usually from schematics, but in your case 25L4006 is to small (512Kb) to be Main Bios. It should be marked as SPI or Main, or M-BIOS, there are photos like one attached which indicates Main Bios
