The show device command displays device information, including name and
type of connection to the system. In this example the Ethernet connection is
ewa0. See Section 4.3 for a description of the show device command and the
device naming convention.
The boot command specifies ewa0 as the boot device. See Section 4.5 for a
description of the boot command.
The boot command accepts the name of a boot device, a boot file name
through the -file option, and boot flags through the -flags option. The
environment variables bootdef_dev, boot_file, and boot_osflags can also be
used to specify the default boot device or device list, the default boot file, and
flag information. When an option and the corresponding environment variable
are both in a command string, the option overrides the environment variable.
The value of the environment variable, however, is not changed. See Section
4.18 for information about environment variables.
The operating system banner prints.
