ZIP archive of 680 KB with BIOS firmware for a Lenovo ThinkCentre M8400T desktop built on the IS7XM motherboard with the Intel Q77 chipset, according to the name. The small size suggests an SPI image for one flash chip or an update package rather than a full multi-chip set, so inspect the contents first. Technicians use such dumps to recover a corrupted BIOS with a programmer. Read and save the original chip contents before writing, and confirm the image size matches the flash chip capacity.
