Compaq DS20E - AlphaStation - 1 GB RAM User Manual page 102

The boot command initializes the processor, loads a program image from the specified
boot device, and transfers control to that image. The syntax is:
boot [-file filename] [-flags [value]] [-halt] [-protocols enet_protocol] [boot_dev]
-file filename The boot file.
-flags [value] Specifies additional information to the loaded image or
operating system. In DIGITAL UNIX, specifies boot flags. In
OpenVMS, specifies system root number and boot flags. This
qualifier overrides the setting of the boot_osflags environment
variable. See the boot_osflags environment variable for a list of
settings and their meanings.
-halt Forces the bootstrap operation to halt and invoke the console
program once the bootstrap image is loaded and page tables and
other data structures are set up. Console device drivers are not
shut down. Transfer control to the image by entering the
continue command.
-protocols Either mop (default) or bootp. This qualifier overrides the
enet_protocol setting of the ew*0_protocols environment variable.
boot_dev A device path or list of devices from which the console program
attempts to boot, or a saved boot specification in the form of an
environment variable. This qualifier overrides the setting of the
bootdef_dev environment variable. Use the bootdef_dev
environment variable to define the default boot device string.
