BIOS package covering the Samsung NP-R428 and R439 laptops, packed into a 1.08 MB RAR archive. The name gives no board number, revision or firmware version, so check the archive and compare against the mainboard markings before use. Samsung shared platforms across these models, but the flash chip and image must still agree in size. Typical use is reprogramming a corrupted SPI flash with a programmer, and the original contents should be saved first to keep serial and configuration data.</p>
