Tiny 10.2 KB RAR archive named after the 25Q80DV, an 8 Mbit (1 MB) SPI flash chip, with no device, brand or board stated. Such small chips commonly hold EC, LAN, or other auxiliary firmware rather than a main BIOS. Because the name is uninformative, open it and check which board the dump came from before use. When writing with a programmer, read and save the original chip first and confirm the image size equals the 1 MB capacity, or it will not fit.
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 @vinafix_bios. Enginerys does not host this file.
