Firmware archive for a Samsung laptop mainboard codenamed Lennon 2-L, revision 1.0, with part number BA41-01748A. BA41 is Samsung's own prefix for main PCB part numbers, which are printed on the board and should be checked before flashing. The RAR of about 1.2 MB likely contains a BIOS dump for the SPI chip. Back up the original flash with a programmer, confirm the image size matches the chip, and then write and verify to restore a failing board.
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.
