BIOS dump for a Sony VAIO VPC-EB series laptop on Sony board MBX-223, with M960 appearing in the name, likely the ODM project code. The 4.00 MB image fits a 32 Mbit SPI flash. Sony MBX numbers identify VAIO motherboards that are often built by Foxconn, so compare the number on the PCB and any project code before use. Read and save the original chip with a programmer first, then write and verify this file if the board matches.
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 @bios_laptop. Enginerys does not host this file.
