First, you need to load the GM bank into the machine. You can do this a couple different ways. You can load them into Ram, or load them into ROM with the boot loader. You can then go into the global menu and page over with the > cursor button until you see the GM bank off/on page. Make sure the setting is set to On, then cursor tot he GM bank page and select auto.
