5.11 Booting an Operating System
The boot command boots the Tru64 UNIX, Linux, or OpenVMS operat-
ing system. You can specify a boot device, operating system-specific
boot information (boot flags), and an Ethernet protocol for network
boots. You can also specify whether the boot program should halt and
remain in console mode.

The boot command initializes the processor, loads a program image from the
specified boot device, and transfers control to that image. If you do not specify a
boot device in the command line, the default boot device is used. The default
boot device is determined by the value of the bootdef_dev environment vari-
able, described in Chapter 4.
If you specify a list of boot devices, a bootstrap is attempted from each device in
order. Then control passes to the first successfully booted image. In a list, al-
ways enter network devices last, because network bootstraps terminate only if a
fatal error occurs or when an image is successfully loaded.
The syntax is:
