BIOS dump for the ASUS S400CA laptop, board revision 2.1, packed in a 3.72 MB RAR. The OK tag in the name means it was reported as a working image. It is intended for reflashing the SPI chip with a programmer after corruption or a failed update, or when installing a blank replacement chip. Check that the motherboard is marked with revision 2.1, read and keep the original contents before writing, and note that serial or system details may need to be restored afterwards.
