BIOS firmware for a board identified only as N68C-M, a 480 KB RAR archive. The name gives no manufacturer or version, so the exact board maker has to be confirmed from the silkscreen and label on the motherboard itself before use. A dump like this is typically written with an SPI or LPC programmer to revive a board with corrupted firmware. Read and store the original chip contents first, compare the extracted image size with the capacity of the fitted flash chip, and confirm the model name matches exactly.
