ASUS ET2040I all-in-one desktop firmware supplied as a 3.49 MB ZIP archive, with 0801 most likely the BIOS version string ASUS uses in its release numbering. No board revision or flash chip type is stated, so inspect the extracted files before use. An image like this serves either for a regular update through the ASUS tools or for reprogramming the SPI chip externally on a unit that does not start. Before writing with a programmer, back up the existing chip contents. Then verify the image size against the chip so the data fits correctly.
