BIOS image for a Sony VAIO board MBX-182, revision 1.0, built by Foxconn under the M722 project code given in the name. Sony labels its notebook boards with MBX numbers, while the ODM project code appears elsewhere on the PCB. The small archive should contain a dump for the SPI flash, written with a programmer when the laptop does not start after a bad update. Confirm the MBX number and revision on the board, and save the original chip contents before erasing.
