Sony VAIO PCG-71C11M BIOS for the VPCEL3S1E, an AMD based model on the Z50-BR motherboard, Sony code MBX-252, supplied as a 1003 KB ZIP. It is meant for reprogramming the flash chip with an external programmer when the laptop stays dead or shows no image. Verify the MBX-252 and Z50-BR markings on the PCB before writing. Read the existing chip and keep the backup, then confirm that the image size equals the flash capacity so the dump fits properly.
