BIOS firmware for the Sony VGN-BX series business notebooks, marked unlocked, which typically means a supervisor or power-on password has been cleared in the image. No board number or chip size is given, so confirm the model's MBX code and the flash chip part before writing. Program it with an external SPI or EEPROM programmer after saving a full backup of the original contents. An image whose size does not match the target chip will not fit, so verify file length against the chip datasheet first.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
