BIOS dump for a Sony VAIO with the model code PCG-71211W, provided as a 4.00 MB binary. The size corresponds to a 32 Mbit SPI flash chip. The name does not mention a motherboard number or revision, so compare the board markings before use. Sony images can include machine-specific data, so backing up the existing chip is essential. Program it with an external programmer when the laptop fails to start because of corrupted firmware, after checking that the chip capacity matches.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosbigarchives. Enginerys does not host this file.
