Sony VAIO BIOS dump for mainboard MBX-143, described as fully working, in a 512 KB RAR archive. Sony labels its VAIO laptop boards with MBX numbers, so the MBX-143 marking should appear on the PCB. The image fits a small SPI or firmware chip and can be written with an external programmer to recover a board with no POST. Despite the working tag, read and save the original chip first, confirm the chip capacity matches the extracted image, and verify the write afterwards.
