Working BIOS and EC firmware set for the Samsung NP530U4B, S01TR model, main board BA41-01888A. The 2.36 MB archive includes both the system BIOS and the embedded controller firmware, useful when power, charging or keyboard faults trace back to a corrupted EC as well as the SPI flash. The BA41 part number is Samsung's own main board code, so confirm it on the PCB. Back up both chips before writing, and check each image size matches its target chip.
