Zipped firmware for the AX78 motherboard, 401 KB in size. Beyond the model name nothing is given: no BIOS version, chipset or chip type appears, so inspect the archive for readme notes or flash tools. A technician can use the image to reprogram a damaged BIOS chip in a programmer, or to roll back after a faulty update. Make sure the PCB is really an AX78, read and store the current chip contents beforehand, and verify the written data against the file once programming is finished.
