BIOS firmware archive for the Toshiba Satellite C70-A, labelled B373J, built on Quanta board DA0BD6MB8D0 revision D. The 12.4 MB RAR holds the dump intended for the SPI flash on this mainboard. A typical use is restoring a board that will not POST after corrupted firmware, writing the image with a CH341A or similar programmer. Read and save the original chip contents first, check that the image size equals the flash capacity, and make sure the PCB carries the same DA0BD6MB8D0 number and revision D marking.
