BIOS dump for the Sony VAIO VPCEB4L1R notebook, which uses the MBX-224 motherboard, packed as a 1.60 MB RAR archive. Sony labels its VAIO mainboards with MBX numbers, and the same MBX-224 board appears in several VPCEB-series models. Technicians use an image like this to restore a laptop that powers on with no display or fails to POST because the firmware is damaged. Before writing, compare the image size with the SPI chip capacity and keep a backup read of the original chip.
