BIOS firmware for a Dell small form factor desktop motherboard marked 14087-1 with code DF9DHSFA, 4.33 MB in RAR format. The name does not give the OptiPlex or Vostro model, so compare the board markings carefully. Such a dump is used to rewrite the SPI BIOS chip with a programmer when the PC does not boot or after a failed update. Save the original chip contents first, since they contain the service tag, and confirm the image size matches the flash chip.
