Samsung NP-R418 notebook BIOS, model variant DA10TH, for main board BA41-01084A, packed in a 1.07 MB RAR. Samsung prints its BA41 part number on the PCB, so match it before use. The dump revives a board that will not boot after corrupted firmware by writing the SPI chip with a programmer such as a CH341A. Read and keep a copy of the original first, since it may contain serial data, and confirm the image size matches the flash chip to ensure a correct write.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
