BIOS dump labelled for a Premium S2300 notebook built on the Clevo board 6-71-W3100-D03A, with images for chips U17 and U31, in a 2.64 MB RAR. Clevo numbers boards as 6-71-xxxxx followed by a version suffix, and many regional brands rebadge Clevo chassis. Two locations usually mean separate system BIOS and keyboard controller firmware. Flash each image to its own chip with a programmer, after saving the original contents, and confirm the board marking reads D03A.
