Firmware dumps for the Sony VAIO VGN-NW350F, model code PGC-7192L, board MBX-218, with the name referring to chips U12 and U46, packed in a 911 KB RAR. MBX numbering is the Sony mainboard convention. The two dumps likely match the two flash chip locations named U12 and U46, so check each file against the matching chip before programming. Use an external programmer, read and store the original contents first, and confirm sizes match the chip capacity.
