starts
a
console-selection
sequence
at
system
boot
time
if
any
of
the
following
is
true:
v
A
console
has
not
yet
been
selected.
v
A
previous
console-selection
sequence
timed-out.
v
A
change
in
the
system
configuration
affects
the
console
(keyboard
installed/removed,
mouse

The
console-selection
sequence
allows
you
to
select
(from
the
appropriate
input
device)
any
one
of
the
available
console
devices.
If
no

If
an
ASCII

is
any
interaction
with
this
terminal,
then:
v
After
OK

AND
v
Before
