Firmware archive for a Compaq-branded HP notebook on board 21NF3AR, with an Intel Core i3-6100U processor and the project marker K21_VC 1. The 22.3 MB RAR contains both the BIOS and EC firmware, so the embedded controller chip can be restored too when the laptop shows no power or charging faults. Identify each image and its target chip before programming. Confirm the board marking, check image sizes against chip capacities, and back up every original chip before writing.
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.
