Raw BIOS image for the ASUS K52JR laptop, mainboard revision 2.0, supplied as a 4 MB binary. The file size corresponds to a 32 Mbit SPI flash chip, so check the marking on the chip before programming. Technicians use such dumps to recover a board that will not start after a failed update or corrupted firmware, writing it with a CH341A, RT809H or similar programmer. Read and save the original chip first, and confirm the board revision printed on the PCB is 2.0 to avoid mismatched firmware.
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 @acheibios. Enginerys does not host this file.
