Firmware dump for a board named LV315KB, Wistron number 17807-3 with part code 448.0DC04.0031, in a 4.82 MB RAR. The LV315KB name suggests a Lenovo 315 series design, but the file itself does not confirm the exact model. Wistron boards carry a five-digit number and a 448 part code on the silkscreen, which should be compared before flashing. Write the image to the SPI BIOS chip with a hardware programmer, keeping a backup of the original and checking that the size fits.
