Dell desktop BIOS image for a motherboard labelled MIB75R-MH, archived as ZIP at roughly 5 MB.

Such files serve to reprogram the SPI flash on a board that no longer boots after a failed update or chip damage. Match the board marking on the PCB, back up the existing chip with your programmer, and check that the image size equals the flash capacity.
