PCWARE IPM31 motherboard firmware, revision 1.03, supplied as a 424 KB RAR. The IPM31 name points to an Intel G31-class desktop board, although the chipset is not spelled out in the name. Programming is done on the SPI flash chip with an external programmer when the BIOS is corrupted or the board stays silent at power-on. Confirm the board model and revision on the PCB, compare the image size with the chip capacity, and keep the original dump as a fallback.
