Firmware for the PT880PRO-A motherboard, revision 1.0, in a 341 KB RAR. The model name refers to the VIA PT880 Pro chipset found on socket 775 era desktop boards. Use it to restore a BIOS chip that no longer boots, programming it with a suitable programmer or reflashing through a hot-swap method. Check the revision printed on the PCB, because a separate 1.1 image exists and revisions are not always interchangeable. Make sure the image size matches the chip capacity and read the original chip before writing.
