Firmware archive for the Lenovo RD650 server, a ThinkServer rack platform. The name states no board number, revision or firmware version, so open the zip and check what it holds, which may be a BIOS image or management controller firmware. Server boards often use more than one flash device, so match each image to the correct chip by size and location. Always read and save the original contents before programming, since servers store configuration and identity data in flash.
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.
