BIOS firmware for the Samsung NP305E5A laptop on the Scala3 platform, board BA41-01820A, with 1517A also noted in the name. Samsung uses BA41 part numbers for its own motherboards. The 1.42 MB zip is intended for reflashing the SPI BIOS chip when the laptop no longer powers up or posts. Match the BA41 number printed on the PCB, dump the existing chip before writing with a programmer, and confirm the image size equals the flash capacity so it fits correctly.
