Raw 32 MB binary firmware image whose name only says it is unpassed and tested OK, meaning a password-removed dump reported to work. No brand, model or board number is given, so its origin must be confirmed from your own notes or by inspecting strings inside the file. A 32 MB image suits a 256 Mbit SPI flash chip and is written with a programmer such as a CH341A. Always read and archive the original chip contents first, and never flash it to a board you have not matched.
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.
