Motherboard BIOS for the SG-80 model, held in a ZIP archive of 349 KB. The name carries only the model code, without brand, revision or firmware version, so confirm the identifier silkscreened on the board before use. A technician would reach for this image to recover a board with a corrupted BIOS, writing it via a DOS flash utility or an external EEPROM programmer. Check that the unpacked image matches the chip capacity and keep a dump of the original firmware first.
