BIOS archive for the PIG41R motherboard marked PM, 604 KB as RAR. The G41 token points to an Intel G41 chipset desktop board; the name gives no revision or vendor, and the meaning of PM is not stated. Technicians use these images to recover a board that fails to post after a bad update by flashing the SPI chip with a programmer. Confirm the PCB marking, save the original chip contents first, and compare the image size with the chip capacity so it fits exactly.
