ASUS BIOS for the K73E and K73SD notebooks, board revision 2.3, firmware version 207, delivered in a ZIP archive. The image suits recovery of a mainboard with corrupted firmware, either through ASUS flashing tools or by programming the SPI chip directly. The K73SD carries discrete graphics while the K73E does not, so match the variant before flashing. Back up the current chip contents to retain serial and board data, and confirm the image size fits the flash chip.
