Sony VAIO VPCF1 series BIOS dump for the Core i7 version on Sony board MBX-215, read from an MX25L320 flash chip. The MX25L3205 family is a 32 Mbit, 4 MB SPI part, consistent with the file size, and M930 in the name is likely the Foxconn board code for this design. Technicians reprogram this image with an SPI programmer to recover dead or bricked VPCF1 units. Check that the MBX number on the motherboard label matches, use the correct chip voltage and read the original before erasing.
