2.6.2 IDE DMA Transfer Access
Use this
field
to enable
or disable IDE
DMA transfer access.
2.6.3 On-Chip IDE Device
IDE Primary Master/Slave PIO/UDMA Mode
(Auto). The
channel has both
a
master and a
slave, making
four IDE devices possible.
Because two IDE devices
may have a different
Mode timing (0, 1,
2, 3, 4), it is necessary for
these
to be
independent. The default setting “Auto” will allow
auto detection to
ensure
optimal
performance.
2.6.4 On-Chip Serial
ATA
Choose the status
of serial ATA. The default setting is
“Auto”
which lets the system
arrange all
parallel and
serial ATA resources
automatically. The “Disabled” setting
disables
the SATA controller.
The
“Combined Mode” combines PATA
and
SATA, and
maximum
of 2 IDE drives in each channel.
The “Enhanced
Mode”
enables
both
SATA and PATA, and a maximum
of 6 IDE drives are supported. The “SATA
Only”
setting means
SATA is operating
in legacy
mode.
2.6.5 SATA PORT Speed Settings
This item allows you to select the SATA port. The choices are “Disabled”, “Fore GenI”
and “Fore GenII”.
2.6.6 PATA IDE
Mode
This
item allows you
to
select
the parallel ATA channel.
Setting options are
Primary and Secondary.
2.6.7 SATA Port
This feature allows
users to
view the SATA port as primary or
secondary channel. If
PATA IDE Mode
is set to “Primary”, it
will display “P1, P3
Secondary” which
means that
SATA1 and SATA3 are secondary. If PATA IDE
Mode
is set to “Secondary,” it will display “P0, P2
Secondary” which means that
SATA0
and SATA2 are secondary.
