Samsung NP-R528 BIOS firmware for the Bremen-L3 board, version 1.2, Samsung part BA41-01227A, shipped as a 1.12 MB RAR. BA41 numbers are Samsung's in-house board codes, so this number should match the label on the PCB. Technicians write the dump to the SPI BIOS chip with a programmer to recover a laptop with no POST, no display or a corrupted update. Back up the current chip contents before writing, and check that the image size corresponds to the flash chip fitted on the board.
