BIOS firmware archive for the HP CQ43 notebook, referencing the CHICAGO_CP_HPC MV board at MB V1, compressed as RAR. The name does not state the chip size or firmware version, so inspect the extracted files and compare the image size with the flash chip on the board. It can be programmed to the BIOS chip with an external programmer to recover a laptop with corrupted firmware. Read and back up the original chip before writing, and confirm the board labelling on the PCB matches before flashing.
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.
