Using the System Control Monitor
B-7
014–002091
BOOT
Starts the system from a specified device.
B
OOT
[device][file]
Description
The command first resets system hardware; it then loads a bootstrap program
from the device you specify in an optional argument [device] . Valid boot device
arguments vary according to your peripheral configuration. After the first-stage boot
completes, the SCM passes the second optional argument,
[file] , to the booted program
for further processing.
Typically, the booted program is the operating system second-stage bootstrap. With
disk and tape boots, you can use the second stage, or
file , argument to specify a
particular program or program parameter (such as run level) to bring up and properly
initialize your operating system.
In a LAN boot, the optional arguments specify the physical LAN connection and the
server system's Internet address. When you omit the second argument in a LAN boot,
the SCM probes the LAN for any server that recognizes your computer's Ethernet
address and then boots the default boot file.
When you use the command with neither optional argument, the SCM attempts
to boot from a default boot path. Refer to the section Changing the Default System
Boot Path" in Chapter 5 for information about using the Change Boot Parameters
menu to set or change this default boot path. If the default boot path is not set or not
valid, the SCM tries to find a bootstrap file on the first SCSI disk.
