BIOS and EC firmware for the Sony VAIO VPCEB23FM on the MBX-223 motherboard, with an M960 code in the name, packed in a 1.60 MB RAR. Sony labels its VAIO boards with MBX numbers on the PCB, so match it before flashing. Having the EC code included helps with power-on and charging faults caused by corrupted embedded controller firmware. Extract it, identify which image goes to which chip, and dump the originals before programming.
