Compaq AlphaServer DS10 Reference Manual page 45

Use the LFU list command to determine the revision of firmware in a
device and the most recent revision of that firmware available in the
selected file. In this example, the resident firmware for each console
(SRM and AlphaBIOS) is at an earlier revision than the firmware in
the update file.
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.
For each device, you are asked to confirm that you want to update the
firmware. The default is no. Once the update begins, do not abort the
operation. Doing so will corrupt the firmware on the module.
The exit command returns you to the console from which you entered
LFU (either SRM or AlphaBIOS).
