Sony VAIO BIOS image of 4 MB for model PCG-71211W, a Sony system model code rather than a motherboard number. A 4 MB dump fits a 32 Mbit SPI flash chip and is written with an external programmer when the laptop does not boot or after a failed update. Because one PCG code can cover several board versions, check the board number on the PCB before relying on this file. Read and save the original chip first, as VAIO dumps hold serial and configuration data.
