ASUS K52F BIOS packaged in a 1.55 MB RAR archive, with the name indicating BIOS version 218. ASUS numbers its laptop firmware releases this way, so the file can also help when checking whether a board carries an older release. Extract the image and match its size against the SPI flash before writing with a hardware programmer. ASUS capsule files from the support site usually carry a header that must be stripped before writing raw to the chip, so verify which form the archive holds and back up the original dump.
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.
