Original BIOS dump labelled QX411, 4 MB, taken directly from a working chip. The QX411 designation matches Samsung's QX-series laptop naming, though the board number and revision are not given here. A 32 Mbit image like this is programmed with an external SPI programmer to revive a board after a corrupted update. Make sure the board on your bench matches, and save the existing contents before erasing. Device-specific serial and MAC data may need correcting afterwards.
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 @bios_laptop. Enginerys does not host this file.
