Small RAR archive whose Vietnamese name translates roughly to software for comparing BIOS source, suggesting a utility for checking or comparing firmware images rather than a dump for a particular board. No brand or model is stated. At 141 KB it likely contains an executable or tool set. Scan it for malware before running, and use it only on copies of dumps, keeping the original chip backup intact.
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.
