Combined BIOS and EC firmware package for the Dell Studio 1558, built on Quanta board DA0FM9MB8D1 revision D. Having both images lets a technician restore the system BIOS and the embedded controller code, which matters when a board shows no power or charging faults caused by corrupted keyboard-controller firmware. Quanta marks its boards with the DA0 prefix and a revision letter, so compare the PCB label first. Dump the original chips with an SPI programmer before writing, and verify each image size matches its chip.
