Firmware image for the Samsung NP305E5Z-S02TH notebook built on mainboard BA41-01822A, intended for a 2MB SPI flash chip. It comes inside a RAR archive of roughly 1.46 MB. BA41 numbers are Samsung in-house board codes, so check the label on the PCB matches before flashing. Typical use is reprogramming the BIOS chip with an external programmer when the laptop powers on without display or the firmware is corrupted. Always back up the existing chip contents, and verify the image size equals the chip capacity, otherwise it will not fit.
