Firmware package for the X441NC laptop board, revision 2.1, containing both a BIOS image and EC firmware in a 5.46 MB RAR archive. Having the embedded controller code alongside the main BIOS is useful when a machine shows no power, charging faults or keyboard issues tied to EC corruption. Each image is written to its own chip with an SPI programmer. Before flashing, back up the original contents, confirm the PCB really reads rev 2.1, and check that each file size matches its target flash chip.
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 @bioshub. Enginerys does not host this file.
