BIOS image for the Biostar B75MU3B motherboard, hardware version 6.x, as a 4.06 MB ZIP. The B75 chipset points to an Intel desktop board. Biostar prints the board version on the PCB, so make sure it is a 6.x revision before flashing. Use the file to restore a dead or corrupted BIOS by writing it with an SPI programmer, or via the vendor update tool if the board still boots. Save the original contents first and check that the image size fits the chip.
