BIOS image for the Gigabyte GA-B250-HD3 desktop motherboard, compressed with RAR and labelled for an 8MB SPI flash chip. Technicians use a dump like this to recover a board with corrupted firmware, for example one that powers on without POST after a failed update. Desoldering the chip or using a clip with an SPI programmer allows a full rewrite. Back up the existing contents first, since they may hold the board serial and MAC data, and verify the image is exactly 8MB.
