BIOS image for the Lenovo ThinkCentre M76 desktop, which uses the M3A780M motherboard according to the name, stored in a RAR archive of about 700 KB. The name states no flash size or revision. Use it to restore a desktop that fails to boot after a corrupted update by writing the SPI chip with a programmer. Read and keep the original contents first, and compare the image size with the actual chip capacity before writing.
