Raw backup dump of the BIOS chip from a Biostar G31-M7 desktop motherboard, stored as a 512 KB binary, which corresponds to a 4 Mbit flash device. Being a backup, it was most likely read directly from a working board rather than taken from a vendor update package. It can be written with a hardware programmer such as a CH341A to revive a board with a corrupted BIOS. Verify the exact model and revision on the PCB silkscreen, save the existing chip contents before erasing, and make sure the target chip is also 4 Mbit.
