BIOS ROM in a ZIP archive for the H61M-HVGS desktop motherboard at version 2.20. The name carries no brand, but H61M-HVGS is an Intel H61 chipset micro-ATX model. The ROM can be written to the board SPI flash with a programmer to recover from a failed update or corrupted firmware. Confirm the board model and PCB revision before flashing. Read the existing chip first as a backup, and check that the file size matches the flash chip capacity.
