BIOS archive for the Sony VAIO VPCEA23EN, regulatory model PCG-61212W, with an Intel Core i3 processor, sized 1.62 MB in RAR format. The name carries no MBX board number, so identify the mainboard code on the PCB to be sure it matches. Repair shops use such dumps to reflash the SPI chip with a CH341A or similar tool when the machine is dead after an update or has a corrupted BIOS. Read and store the existing chip first, and confirm the image size fits the flash capacity before writing.
