BIOS dump for the Sony VAIO VPCEL2S1R, model code PCG-71C12V, on the Sony-numbered MBX-252 mainboard in its AMD platform version. The compact 1 MB rar archive is used to reflash the SPI BIOS chip with a programmer when the laptop stays dark or loops after a bad update. Confirm the MBX-252 marking on the PCB, save the original chip contents before erasing anything, and check that the image size matches the capacity of the installed flash chip.
