Sony VAIO BIOS dump archive covering two Sony board numbers, MBX-273 and MBX-276, packed together in a 3.56 MB RAR. The name does not say which image belongs to which board or give a version, so extract and identify each file before flashing. Sony prints the MBX code on the motherboard silkscreen, which lets you match it reliably. Always back up the existing SPI flash with a programmer first, and make sure the image size matches the chip capacity, otherwise the write will fail or the board will not post.
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 @biosarchive. Enginerys does not host this file.
