Samsung laptop BIOS archive labelled P11ABK, linked to Samsung boards BA41-02037A and BA41-02038A. The short name looks like a Samsung BIOS version code, but it does not state the model or the flash chip. Samsung uses the BA41 prefix for its own mainboard part numbers, so compare the sticker or silkscreen on your PCB with these numbers. Unpack the ZIP, check that the image size matches the SPI chip, and read a backup of the original contents with a programmer such as a CH341A before flashing.
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.
