Firmware package for the Samsung NP-R439 laptop, model code DA07IN as stated in the name, held in a 1.58 MB RAR archive. The name does not specify a board number, revision or whether EC firmware is included, so inspect the archive contents first. A BIOS image like this is used to restore the flash chip with an external programmer when the laptop does not boot. Read and back up the existing chip before writing, and verify the image size against the chip capacity.</p>
