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.
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.
