Firmware dump for the PIG41R motherboard, Wistron number 08174-1, with the code 3AG01 in the name, packed as a 657 KB zip. The small size suggests a compact BIOS image intended for direct writing to the board's SPI flash. Wistron uses five-digit numbers with a dash revision such as 08174-1, printed on the PCB silkscreen, so confirm the match before flashing. Read and store the original chip first, check that the image size equals the chip capacity, and verify the write afterwards to avoid a board that stays dead.
