Allows
you
to
choose
how
the
SATA
controller
and
devices
are
accessed
by
the
operating
system.
There
are
three
supported
options:
IDE,
RAID,
and
AHCI
(default).
IDE
-
This
is
the
most
backwards-compatible
setting
of
the
three
options.
Operating
systems
usually
do
not
require
additional
driver
support
in
IDE
mode.
AHCI
(default
option)
-
Allows
operating
systems
with
AHCI
device
drivers
loaded
to
take
advantage
of
more
advanced
features
of
the
SATA
controller.
NOTE:
The
RAID/AHCI
device
driver
must
be
installed
prior
to
attempting
to
boot
from
a
RAID/
AHCI
volume.
If
you
attempt
to
boot
from
a
RAID/AHCI
volume
without
the
required
device
driver
installed,
the
system
will
crash
(blue
screen).
RAID
volumes
may
become
corrupted
if
they
are
booted
to
after
disabling
RAID.
NOTE:
RAID
is
not
available
on
USDT
systems.
Allows
you
to
execute
self-tests
on
ATA
hard
drives
capable
of
performing
the
Drive
Protection
System
(DPS)
self-tests.
NOTE:
This
selection
will
only
appear
when
at
least
one
drive
capable
of
performing
the
DPS
selftests
is
attached
to
the
system.
Allows
you
to:
●
Specify
the
order
in
which
EFI
boot
sources
(such
as
a
internal
hard
drive,
USB
hard
drive,
USB
optical
drive,
or
internal
optical
drive)
are
checked
for
a
bootable
operating
system
image.
Each
device
on
the
list
may
be
individually
excluded
from
or
included
for
consideration
as
a
bootable
operating
system
source.
EFI
boot
sources
always
have
precedence
over
legacy
boot
sources.
●
Specify
the
order
in
which
legacy
boot
sources
(such
as
a
network
interface
card,
internal
hard
drive,
USB
optical
drive,
or
internal
optical
drive)
are
checked
for
a
bootable
operating
system
image.
Each
device
on
the
list
may
be
individually
excluded
from
or
included
for
consideration
as
a
bootable
operating
system
source.
●
Specify
the
order
of
attached
hard
drives.
The
first
hard
drive
in
the
order
will
have
priority
in
the
boot
sequence
and
will
be
recognized
as
drive
C
(if
any
devices
are
attached).
NOTE:
You
can
use
F5
to
disable
individual
boot
items,
as
well
as
disable
EFI
boot
and/or
legacy
boot.
NOTE:
MS-DOS
drive
lettering
assignments
may
not
apply
after
a
non-MS-DOS
operating
system
has
started.
