Booting the Operating System
The boot command is used to boot the operating system. The boot
command initializes the processor, loads a program image from
the specified boot device, and transfers control to that image.
Syntax: 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 Tru64 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
enet_protocol
Either mop (default) or bootp. This qualifier overrides
the 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.
