Boot Console Handler
Setting the Auto Boot and Auto Search Flags
Setting the Auto Boot and Auto Search Flags
The
auto boot
and
auto search
flags are variables stored in the system’s nonvolatile
memory. (Nonvolatile memory retains its contents even after power is turned off.) If you
reset these flags to new values, the change takes effect the next time you reboot the
workstation.
The
auto boot
flag boots the operating system whenever the workstation is turned on.
If
auto boot
is set to on, the system automatically attempts to boot the operating system
when turned on. If
auto boot
is set to off, the system enters the boot administration mode
of the Boot Console Handler’s user interface.
The state of the
auto search
flag determines how the system seeks a boot device during
auto boot. If
auto search
is set to on, the system will search for other boot devices if the
primary boot device is not available. If
auto search
is off, the system will default to the
boot administration mode if it can’t see the primary boot device.
To examine the state of the
auto boot
and
auto search
flags, type the following at the
prompt and press
Enter
:
Configuration Menu: Enter command> auto
To change the state of the auto boot or auto search flags, type the following at the prompt
and press Enter:
Configuration Menu: Enter command> auto boot
state
or
Configuration Menu: Enter command> auto search
state
where
state
is on or off.
The
auto search
command searches for devices in the following order:
Primary boot path (can be set by the user)
Alternate boot path (can be set by the user)
PCI 1 through PCI 4 (plug-in interface cards)
Low-voltage differential SCSI (built-in)
LAN (built-in)
IDE (built-in)
