Samsung brand bundle numbered 09, a 594 MB RAR archive whose name lists no specific model or board. Its size suggests a broad collection of repair material, likely schematics, boardviews and firmware for Samsung laptops identified by BA41 board numbers, but the contents need checking after extraction. Match any file you use to the board number and revision on the PCB. For BIOS images, read the original chip with a programmer first and confirm the dump size equals the flash capacity.
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 @videocard_notebook_resistance. Enginerys does not host this file.
