Firmware archive for the ASUS Prime B350-Plus AM4 motherboard, board revision 1.05, supplied as a 5.34 MB RAR file. The name states no version number or tested status, so open the archive and inspect the contents before use. Such a dump is normally programmed onto the BIOS SPI chip with an external programmer when the board is bricked or the onboard flash is corrupt. Back up the existing chip, verify the revision silkscreen on the PCB, and make sure the image size matches the flash chip capacity before writing.
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.
