Firmware dump for the ASUS U47A, with DDR3 mentioned in the name, packed as a 3.54 MB RAR archive. The DDR3 note likely refers to the memory configuration of the board the image came from. No revision or BIOS version is given. This kind of file is written to the SPI BIOS chip with an external programmer to recover a non-booting laptop. Save the existing chip content before erasing, compare the board markings, and check that the extracted image is the same size as the installed flash chip.
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.
