BIOS for the ASUS X541SA laptop, mainboard revision 2.0, intended for a GD25LQ64C flash chip that runs at 1.8 V. The rar is only 49.9 KB, so it compresses well or may be a partial image; check the extracted size before writing. A 1.8 V chip needs a programmer or adapter that supports that voltage, since a standard 3.3 V CH341A can damage it. Confirm revision 2.0 on the PCB, read and save the original chip first, and verify the image matches the 8 MB capacity of the chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
