Archive for an HP ProLiant DL360 Gen9 server, marked OK tested, packed as a 15.6 MB RAR. The name does not detail what is inside, but such packages usually carry a system ROM or flash dump for reprogramming the board's SPI chip when firmware is corrupted. Extract it and identify each file and its size before writing anything. Match the image size to the flash chip capacity, keep a backup read of the original chip, and verify after programming with a tool such as a CH341A or similar programmer.
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 @hrtechno. Enginerys does not host this file.
