BIOS image archive for the Biostar H61MGC desktop motherboard, an Intel H61 chipset board, compressed as a 1.80 MB RAR; note the index lists the brand as ECS while the name says Biostar. Desktop boards of this generation store firmware on an SPI flash chip that can be rewritten out of circuit with a programmer when the board no longer posts. Read and keep a backup of the original chip first, confirm the model on the board matches, and check that the image size equals the flash chip capacity.
