Tested BIOS for the Biostar H61MLV2 motherboard, version 8.0, filed under ECS and packed as a 4.86 MB RAR archive. The H61 is an Intel chipset for LGA1155 processors. Biostar prints the board version on the PCB, and different versions may need different images, so check that it reads 8.0. Use an SPI programmer to restore the chip when the board fails to post, first reading and saving the original contents and confirming the image size matches the flash chip.
