BIOS firmware for a board named A785GM-AD3, version 1.0, in a ZIP of about 671 KB. The name points to an AMD 785G chipset desktop board, though the manufacturer is not stated. Such an image is written to the SPI or LPC flash chip with a programmer such as a CH341A when the board is bricked or the BIOS is corrupted. Read and save the original chip contents first, confirm the board model and revision on the PCB, and check that the image size matches the chip capacity before writing.
