BIOS and EC firmware for the HP 430 laptop, for the board named CHICAGO CP HPC MV MB V2, where MV marks the mass-production version of the design. The ZIP is 3.86 MB and includes both the system BIOS and embedded controller firmware. The EC image matters on HP boards because a damaged EC can prevent power-on or charging. Program the files with an external flasher onto the correct chips, back up the originals first, and confirm the image sizes match each chip and the board name on the PCB matches.
