BIOS and EC firmware for a board identified as NDBT140x V1.1, packed in a 3.06 MB RAR. The name does not give the laptop brand or model, so match the board marking NDBT140x and version 1.1 printed on the PCB before use. The EC image controls power sequencing, battery charging and keyboard functions, while the BIOS image restores the system firmware. Flash both with an SPI programmer only after reading and saving the existing chip contents, and confirm each file's size equals its target chip capacity.
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.
