BIOS firmware for the Samsung NT270B4E laptop, packed in a 4.58 MB RAR archive; NT prefixes are typically used for Samsung models sold in the Korean market. The name gives no board number or version, so identify the mainboard code printed on your PCB before use. The image is meant for restoring the SPI flash when a unit is bricked or fails POST. Read and store the original chip contents first, check the extracted file size against the chip capacity, and only then program it with an external flasher and verify the write.
