BIOS image for the Gigabyte B450M DS3H WIFI desktop board, labelled as a working 16MB dump and compressed in a RAR of about 21.8 MB. A dump taken from a functioning board is useful for recovering a unit with corrupted firmware by reprogramming the SPI flash directly with a programmer. The board revision and BIOS version are not stated, so confirm compatibility with your PCB. Back up the existing chip before erasing, and check that the chip is 16MB so the image fits.
