BIOS and EC firmware package for the Dell Studio 1558 on Quanta board DAFM9CMB8C0, revision C. Quanta uses the DA plus project code pattern, here FM9, for boards it builds for Dell. Having the embedded controller firmware alongside the system BIOS helps when a laptop does not power on or charge, as both chips may need reprogramming. Use a programmer to read and back up each chip, confirm the board number and revision on the PCB, and check that each image matches its chip size.
