BIOS firmware for a Biostar H61MLV2 desktop motherboard, packed as a 2.54 MB RAR archive. The index lists the brand as ECS, while the file name itself says Biostar. The H61 in the model name points to an Intel H61 chipset board. Technicians use a dump like this to reprogram the SPI flash chip with an external programmer when the board no longer posts after a failed update or corruption. Before writing, read and save the original chip contents. Also confirm the image size matches the flash capacity and the board model printed on the PCB.
