BIOS package for the Gigabyte GA-B250M-Gaming 3 desktop motherboard, revision 1.0, in a 5.45 MB ZIP. The name does not state the version number, so check it inside the archive. The B250 chipset implies a 7th/6th gen Intel socket board, but verify compatibility on the silkscreen. The image can be written with Gigabyte's own update tools when the board still boots. On a dead board it can be programmed into the SPI chip with a CH341A-type programmer. Back up the existing chip first and confirm that revision 1.0 is printed on the PCB.
