Compaq AlphaServer GS60 Operation Manual page 91

The SRM command show device is useful for locating the boot device for the
Loadable Firmware Utility, or the boot device for the operating system for OpenVMS
or DIGITAL UNIX systems. The show device command is also helpful in isolating
non-functioning I/O devices detected by a test command. Note that, for Windows NT
systems, the device mnemonics shown by show device are not the same as the device
mnemonics used by AlphaBIOS, which in turn are different from the mnemonics used
by the Windows NT operating system.
The show device command provides the following device information:
