BIOS image for the Sony VAIO MBX-189 mainboard with the M762 board code, a 2.00 MB binary for a 16 Mbit flash. No revision or version is stated. Sony pairs MBX numbers with M-series codes on its laptop boards, and both should match the PCB before the file is used. Typical use is reflashing the SPI chip with a programmer when the laptop does not power on or POST because of firmware corruption; keep a backup of the original chip contents.
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.
