Binary of 4 MB named 5040 BIG and marked OK twice, suggesting a verified working dump of the larger of two chips on a model numbered 5040. A companion small 256 KB file exists, which hints that the board carries both a main BIOS chip and a smaller EC or second flash. The brand and board number are not stated, so confirm the platform first. This image fits a 32 Mbit SPI chip; back up the original and verify after writing.
