Firmware dump for the ASUS A53S notebook, marked as revision 3.1 of the mainboard, packed in a 1.57 MB 7z archive. The name gives no chipset, GPU or flash chip details, so open the archive to check the image size against the capacity of the SPI chip on your board. A dump of this kind is written with an external programmer when the original BIOS is corrupted. Always keep a backup of the existing chip, since it holds serial and MAC data, and verify the board revision 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 @biosfiles. Enginerys does not host this file.
