Sony VAIO firmware for the model coded VJF151C01N, built on a Quanta board DAHKDAMB6A0 at revision A, in a 3.40 MB RAR archive. Quanta, the ODM behind this board, uses DA-prefixed numbers that appear on the PCB silkscreen together with the revision letter. Check both match before writing anything. Expect a BIOS image for the SPI flash, which can be programmed with an external programmer. Read and keep the original chip contents first, and make sure the file size equals the chip capacity so the image fits.
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.
