BIOS firmware package for the Dell Studio 1640, labelled for the version fitted with Nvidia discrete graphics. The RAR archive is 1.15 MB and the name gives no board number or revision, so confirm the motherboard and its GPU variant before use, because Studio 1640 boards came in different graphics configurations. Technicians typically write such a dump to the SPI BIOS chip with a programmer to recover a board that will not post. Read and save the original chip contents first, and check that the image size matches the flash capacity.
