Firmware archive for the Sony VAIO VGN-CS36H, which uses the MBX-196 motherboard made by Quanta with board number DA0GD2MB8E0. The name carries no revision, so look at the PCB silkscreen for the rev letter before use. At 857 KB the RAR probably holds a raw BIOS image for writing to the SPI flash with a programmer. Dump and keep the existing chip first, and ensure the image length matches the flash device, as an oversized or undersized file cannot be written correctly.
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.
