BIOS dump labelled as working for the Samsung NP300E5Z laptop, with the board names SCALA3-15 and PETRONAS-15 given in the name, the internal project codes Samsung used for this platform. Contained in a 2.10 MB ZIP. Reported working status makes it a candidate for recovering a board with corrupted firmware via an SPI programmer. Check that your motherboard silkscreen shows the same project name, back up the existing chip first, and confirm the image size fits the flash memory installed.
