Tiny 294-byte zip named after Ventoy, the open-source tool for creating bootable USB drives from multiple ISO images. At this size it cannot contain the Ventoy program or any BIOS image, so it is probably a configuration file, a shortcut or a broken archive, despite being filed under firmware. The name gives no board or model information. Open it to check what it holds and do not write it to any flash chip; obtain Ventoy itself from its official project if needed.
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 @lappysan. Enginerys does not host this file.
