Raw 4 MB BIOS dump for the ASUS A53S, which is the same board as the K53SV, at mainboard revision 3.1. With a size matching a 32 Mbit SPI flash chip, it is meant for direct programming with a hardware programmer rather than the vendor update utility. Revision 3.0 and 3.1 boards are distinct, so confirm the revision printed on the PCB. Save a backup of the existing chip before writing, then verify after programming.
