Firmware archive named PX915P4C-PRO, 3.01 MB in rar format, with no brand or revision in the name. The label resembles a desktop motherboard model for an Intel 915P platform, but confirm the model printed on the board before use. Older desktop boards usually store the BIOS on a socketed or soldered SPI or FWH chip that can be rewritten with a programmer to fix a failed update. Read and keep the original chip contents first and check the chip type and capacity match the image.
