BIOS dump of 8 MB for the Dell Latitude 3340, board 13229-1 revision A00, reported as working. The 13229-1 number matches the Wistron board numbering scheme. The BIN file can be written directly to the SPI flash with a hardware programmer to recover a dead or bricked board. Read and save the existing chip before erasing it, check that the chip capacity is 8 MB, and compare the board label so you do not flash firmware meant for a different revision.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
