BIOS dump for the ASUS N53SV laptop, board revision 2.1, sized for a 4 MB flash chip according to the name and stored in a 2.43 MB RAR. It is meant for reprogramming the SPI BIOS chip with an external programmer when the notebook fails to post or the firmware is damaged. Confirm the revision printed on the mainboard is 2.1 and that the chip is 4 MB, since a mismatched image will not fit. Back up the original contents before erasing, as they hold serial and system data.
