BIOS for the Biostar H61MV3B desktop motherboard, revision 6.0, marked as tested and working. The H61 chipset supports second and third generation Intel Core processors and stores firmware on an 8 pin SPI flash chip. The RAR is around 1.6 MB and the image is meant to be written with an external programmer when the board will not post. Check the revision silkscreened on the PCB, back up the original chip and confirm the size matches before writing.
