Firmware archive for the ASUS-style K52JR notebook mainboard, revision 2.0, supplied as a 1.78 MB RAR. The name states only the model and board revision, so contents are probably a raw BIOS image for the SPI flash. Use it to restore a board with a corrupted BIOS by writing it through an external programmer and clip or after desoldering the chip. Confirm the revision silkscreened on the PCB is 2.0, keep a backup of the original dump, and make sure the file size matches the flash chip capacity.
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.
