Dell Inspiron 7537 BIOS archive, 3.49 MB ZIP, referencing board 12311-2 and the code DOH50A13. The 12311 numbering follows Wistron, the ODM behind this board, and the -2 suffix should be checked against the PCB marking. Such a dump is written to the SPI BIOS chip with a programmer to recover a board that does not post or has corrupted firmware. Unpack it to see what images are included, dump and keep the original chip contents first, and confirm that the file size fits the chip.
