Samsung NP-R420 BIOS for the Intel version without discrete graphics, on motherboard BA41-01084A, delivered as a 1.08 MB ZIP. BA41 numbers are Samsung's in-house main board part codes and must match the PCB label. The dump is written with an external programmer to recover a laptop that stays dark after a failed update. Confirm that your board has no dedicated GPU, read and save the original chip contents, and make sure the image size matches the installed flash chip.
