BIOS firmware for a Sony VAIO mainboard MBX-196, built by Quanta on its GD2 platform with PCB number DA0GD2MB8E0, revision E. Quanta boards follow the DA0 plus project code plus MB pattern, which helps match the right board. The 857 KB RAR likely contains an SPI image for recovery with an external programmer. Before flashing, save the original chip contents and confirm the Rev E marking, then compare file size with the chip capacity, since a mismatched image will not fit.
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.
