Using
the
Setup
Utility
The

Utility
program
is
stored
in
the
electrically
erasable
programmable
read-only
memory
(EEPROM)
of
your
computer.
The
Setup
Utility
program
is
used
to
view
and
change
the
configuration
settings
of
your
computer,
regardless
of
which
operating
system
you
are
using.
However,
the
operating-system
settings
might
override
any
similar
settings
in
the
Setup
Utility
program.

the

Utility
program,

If
your
computer
is

start
this
procedure,

down
the
operating
system
and
turn
off
the
computer.
2.
Repeatedly
press
and
release
the
F1
key
while
turning
on
your
computer.
Note:
If
a

the

program
menu
is
not
displayed
until
you
type

might
start
automatically
when

that

you
must
use
the
keyboard.
The

By

Password
considerations
A
password
can
be
any
combination
of
up
to
twelve
characters
(a-z
and

and

reasons,
it

adhere
to
the
following
rules:

at
least
eight
characters
in

at
least
one
