As I know, this is on one hand dependend on the used chipset and on the
other haned dependend on the ATA driver. Those chipsets with NCQ AND
AHCI (mostly Intel ICH based chipsets) should be managed and addressed
by a suitable driver (as far as I know not yet available for FreeBSD 6.X).
As someone can read at the nVidia homepage, their nForce4-SLI chipsets
also supports NCQ, but it is proprietary thing, not commonly accessible
via AHCI. And due to the lack of information, like most of nVidias
goodies for computers, there is no access to this feature via the open
If I'm wrong someone should correct my statement.
