BIOS dump for ASUS K56CB and K46CM laptops, revision 2.0 mainboard, described in the name as a working image and supplied in a 4.43 MB RAR archive. A dump like this is written straight to the SPI flash chip with a programmer such as a CH341A when a board will not start because of corrupted firmware. Always read and save the original chip contents before erasing, check the extracted image size against the flash capacity, and confirm the board revision on the PCB matches 2.0 so the image fits the hardware.
