BIOS firmware for ASUS P43E and A43E notebooks, which share the K43SD mainboard, here labelled revision 2.2. Packed as a 1.86 MB zip, it is meant for recovering a board with corrupted firmware by writing the image directly to the SPI flash using a programmer such as a CH341A. Extract the contents and confirm the dump size equals the chip capacity. Before flashing, save the original chip contents and make sure the board revision on the PCB reads 2.2, because K43 variants differ between revisions.
