Sony VAIO VPCEG series BIOS dump for the MBX-250 mainboard, using Sony's MBX board numbering. The name marks it as a Clear Me image, which generally means a cleaned dump with user settings or passwords removed, though the exact changes are not described. The 1.73 MB ZIP contains the binary for writing to the SPI flash with a programmer. Confirm the MBX number on the PCB, check that the image size matches the chip, and save the original read before writing.
