Raw 4 MB BIOS image for the Samsung R590, Bremen-M board revision 3.1, with 11JB in the name likely marking the firmware version, stored as a plain BIN file. A 4.00 MB image corresponds to a 32 Mbit SPI flash chip, so check the chip on the board matches before writing. Technicians program it with an external programmer to restore a dead or bricked laptop. Read and keep the original contents beforehand, and confirm the board marking shows Bremen-M revision 3.1, since images from other revisions may not work.
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 @efibios. Enginerys does not host this file.
