Duplicate copy of a working ROM dump for the ASUS K53SD main board, revision 2.3, from a K53E-SX690 laptop, at 4MB. A second copy is useful for checking against the first, since matching checksums confirm a clean read. Programmed through an SPI programmer, it can restore a board with corrupted firmware. Verify the revision printed on the board, keep a backup of the existing chip contents before writing, and make sure the flash IC is 4MB.
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 @biosfilebins. Enginerys does not host this file.
