BIOS firmware archive for a motherboard numbered 14291-1, with the name also carrying the marking PWB51VP4 and revision A00. The 14291-1 style of number follows the Wistron pattern, so the board was likely built by Wistron for another brand. The RAR is 5.14 MB and should be unpacked first to see which image files it holds. Compare the number and revision printed on the PCB before use, read and save the original SPI chip with a programmer, and confirm the image size matches the flash capacity.
