BIOS image for a desktop board identified as G31CHL3 AA, marked as working. G31 points to an Intel G31 chipset platform, although the manufacturer is not given in the name. The 695 KB RAR probably holds a dump for an 8 Mbit SPI or FWH chip. Use it to recover a board that powers on without display due to corrupted firmware. Read and keep the original chip contents first, verify that the image size equals the chip capacity, and match the board code printed on the PCB.
