BIOS and EC firmware for a Sony VAIO laptop with board reference V110 H and PCB number 1P-0121700-8011, in a 9.20 MB RAR archive. Sony boards use 1P- part numbering, so compare it with the label on your PCB. The EC image restores embedded controller functions such as power-on and charging, while the BIOS image goes onto the SPI flash. Read and save the existing chips with a programmer before writing, and make sure each file size matches its target chip.
