BIOS dump for a Wibtek B75-M motherboard, an Intel B75 chipset desktop board, in a 4.32 MB RAR. The name carries no revision or version number, so compare the PCB markings carefully before use. Such a file is typically flashed onto the SPI chip with an external programmer to repair a board that powers on without video or after a failed update. Always save the existing chip contents first. Then check that the image size matches the flash capacity printed on the chip, otherwise the write will fail.
