Zip archive of 367 KB for the Gigabyte GA-M61SME-S2 desktop motherboard, with no revision in the name. The small size suits a BIOS image for an older low-capacity flash chip, though the contents should be confirmed after extraction. Gigabyte prints the PCB revision on the board, and firmware is often revision-specific, so match it before use. Read and save the original chip with a programmer first, then confirm the dump size matches the chip before writing.
