The update command updates the device specified or all devices. In this
example, the wildcard indicates that all devices supported by the selected
update file will be updated. Typically LFU requests confirmation before
updating each console's or device's firmware. The -all option eliminates the
update confirmation requests.
The exit command returns you to the console from which you entered LFU
(either SRM or AlphaBIOS).
