Firmware for a board model PT880PRO-A-V revision 1.1, marked ASLI, which in Indonesian means original, so likely a stock dump. The rar is 682 KB. The PT880 label suggests a VIA PT880 chipset desktop board, but no brand is given, so verify the model printed on the PCB. Boards of that era used small parallel or LPC flash chips that are rewritten with a programmer when a failed flash leaves the board dead. Read the old chip first and confirm the chip size matches the image before writing.
