Using
IDE
Drives
Setup
In
addition
to
listing
the
different
IDE
devices,
there
are
options
for
configuring
the
serial
and
parallel
IDE
controllers.
Parallel
ATA
This
setting
allows
the
user
to
disable
one
or
both
of
the
parallel
IDE
controllers.
Serial
ATA
This
setting
allows
the
user
to
disable
the
serial
ATA
controllers.
Native
Mode
Operation
This
setting
is
only
available
when
the
serial
ATA
controller
is
enabled.
This
allows
the
user
to
specify
whether
the
parallel
and
serial
ATA
controllers
will
operate
in
″legacy″
or
″native″
mode.
By
default,
they
will
operate
in
native
mode
unless
both
parallel
ATA
controllers
are
populated
and
a
serial
ATA
drive
is
present.
Then
the
serial
ATA
drive
will
become
″native″
mode.
The
user
can
select
Automatic
or
the
serial
ATA
controller
to
run
in
″native″
mode.
However,
running
in
″native″
mode
might
not
work
with
older
operating
systems.
