Firmware archive for the AN-M2HD motherboard, a 373 KB zip with no version or chip information in its name. It sits beside a separate AN-M2 package, so take care not to confuse the two related models when picking an image. Typical use is restoring a board with damaged BIOS contents, flashing with a programmer when the system no longer posts. Read out and save the existing chip first, compare the board label with the file, and verify that image size and flash capacity agree before programming.
