Combined BIOS and EC firmware package for boards labelled MU5DC and CH7DC, revision 2.0, in a 6.56 MB ZIP. The name gives no laptop brand or model, so identify the target from the PCB markings before use. With both images present, a technician can reflash the system BIOS chip and the embedded controller flash using a programmer, which helps with dead boards, charging faults or no power-on. Back up the original chips first and make sure each image matches its flash chip size.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
