HP Pavilion x360 m3 BIOS dump, with 3165ngw in the name, likely the Intel 3165 wireless module, and the token PU5201. The file is a 4.67 MB RAR archive intended for programming the SPI flash with an external tool such as a CH341A-type programmer to recover a board that will not POST. The name does not state a board number, so verify the model against the motherboard markings. Always read and keep a copy of the original chip, including serial and system data, before flashing the image.
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.
